Answers

Answer 1

When attractive forces between molecules are strong in a liquid, the liquid can be described as solid.

How are attraction forces in solid, liquid, and gas?A solid's internal kinetic energy produces a force that is weaker than the attraction forces between its molecules. The molecules in a solid are kept in close proximity to one another by attraction forces as the attractive forces between molecules are strong.In a liquid, there is more kinetic energy than there is in a solid. In a solid, the stiff attraction between molecules can be broken by kinetic energy. The molecular attraction between them is still strong enough to keep the liquid's molecular structure intact.In comparison to kinetic energy in molecules, kinetic energy in a gas is substantially strong. In a gas, the attraction between the molecules is significantly weaker than the kinetic energy. In this situation, there is no longer any molecular attraction.

how do you balance a element year9 chemistry ?

Answers

Answer:

Balancing a chemical equation involves a certain amount of trial and error. In general, however, you should follow these steps:

Count each type of atom in reactants and products. Does the same number of each atom appear on both sides of the arrow? If not, the equation is not balanced, and you need to go to step 2.

Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances. Use the smallest coefficients possible. Warning! Never change the subscripts in chemical formulas. Changing subscripts changes the substances involved in the reaction. Change only the coefficients.

Repeat steps 1 and 2 until the equation is balanced.

Answers

By using the no. of moles, the mass of AgCl formed is determined to be 23.50g.

The mass of a material that includes the substance's particles is referred to as a mole.

The number of moles of a material equals to the ratio of its given mass to the mass of one mole of that substance in a chemical reaction. A mole / the no. of moles of any substance is equal to Avogadro's number, which is 6.023 x [tex]10^{23}[/tex]. Additionally, no. of moles is employed to represent concentration measurements like mole per liter and molecular weight.

[tex]2AgNO_3 (aq) + CaCl_2 (aq) \rightarrow 2AgCl (s) + Ca(NO_3)_2 (aq)[/tex]

Since [tex]AgNO_3[/tex] is in excess, the amount of product formed will be decided by the quantity of [tex]CaCl_2[/tex], which is the limiting reagent.

1 mole of [tex]CaCl_2[/tex] produces 2 moles of AgCl

No. of moles of [tex]CaCl_2[/tex] = mass of [tex]CaCl_2[/tex] / molar mass of [tex]CaCl_2[/tex]

No. of moles of [tex]CaCl_2[/tex] = 9.11 / 110.98 = 0.0820 moles

No. of moles of AgCl formed = 2 x 0.0820 = 0.164 moles

Mass of AgCl formed = No. of moles x molar mass

Mass of AgCl formed = 0.164 x 143.3 = 23.5012g

Answers

vaporization's enthalpy is 40.88 kJ/mol.

What exactly is vaporization enthalpy?

The amount of energy (enthalpy) required to turn a portion of a liquid into a gas is known as the enthalpy of vaporization (symbol Hvap), also known as the (latent) heat of vaporization or heat of evaporation.

Enthalpy of vaporization  ∆Hvap

T1 = 25 + 273 = 298 K

T2 = 100 + 273 = 373 K

Cp(1) = 0.07529 kJ/K.mol

Cp(2) = 0.03358 kJ/K.mol

So dHvap at 100 oC would be,

dHvap = dHvap at 25 oC + (Cp(2) - Cp(1)(T2-T1)

= 44.01 + (0.03358 - 0.07529)(373-298)

ryan is a chemistry student that enjoys hot tea. he wants to determine how much ice is needed to cool 250.0 ml of tea to an optimal drinking temperature of 57.8 c. macmillan learning the method ryan uses to prepare his tea results in an initial temperature of 79.1 c. the average mass of an ice cube from the ice tray ryan uses is 18.8 g and has a starting temperature of - 8.33 deg * c assume that the heat capacity of tea is the same as pure water, and assume no heat is lost to the surroundings what mass of ice is needed to reach the optimal temperature of 57.8^ c^ prime ?

Answers

Ryan calculates that he requires 4 ice cubes for 250mL of hot tea to reach the optimal drinking temperature by using the specific heat capacity of tea.

A substance's potential to hold heat is indicated by its specific heat capacity. This substance size reflects the amount of heat required to raise a certain volume of a material's temperature by one Kelvin. Specific heat capacity is a distinguishing feature of every substance and is useful for material identification.

Given:

Final temperature of system is 57.8℃

dT1 = 79.1 - 57.8 = 21.3℃

dT2 = 0 - (-8.33) = 8.33℃

dT3 = 57.8 - 0 = 57.8℃

Mass of tea, m1 = 250.0mL = 250.0g = 0.250kg

Specific heat capacity of tea, C1 = 4186 J/kg℃ = Specific heat capacity of water

Specific heat capacity of ice, Ci = 2090 J/kg℃

Mass of each ice cubes, m of i = 18.8g

Latent heat of fusion of ice, Lf = 334 kJ/kg

To find:

No. of ice cubes required = ?

Calculations:

Suppose equilibrium temperature is T, then

Heat released by Tea = Heat gained by Ice

Q1 = Q2

m1x C1x dT1 = mi x Ci x dT2 + mi x Lf + mi x Cw x dT3

0.250x 4186 x 21.3 = mi x (2090 x 8.33 + 3.34 x [tex]10^4[/tex] + 4186 x 57.8)

mi = 0.250 x 4186 x 21.3 / (2090 x 8.33 + 3.34 x [tex]10^4[/tex] + 4186 x 57.8)

mi = 0.0761kg = 76.1g

Mass of ice required = 76.1g

Number of ice cube required will be:

n = Total mass of ice/mass of each ice cube

n = 76.1/18.8

n = 4.04 ice cubes = 4.0 ice cubes

Result:

Ryan requires 4 ice cubes to bring 250mL of hot tea to the optimal drinking temperature.

pure benzene freezes at 5.53°c and boils at 80.10 oc. a solution of a certain solute in benzene freezes at 1.00 oc. what is the boiling point of this solution? for benzene, kf

Answers

Based on the cryoscopic constant and the ebullioscopic constant of benzene, we can calculate that the boiling point of this solution will be 82.33 °C.

For this calculation, we require both the cryoscopic constant (Cf = 5.12 °Ckg/mol) and the ebullioscopic constant (Cb = 2.52 °Ckg/mol) for benzene. These describe the shifts in benzene's freezing and boiling points based on the molality of the solution (with benzene as the solvent).

Because we know that the change in benzene's freezing point is 5.53 °C - 1.00 °C = 4.53 °C, we can now calculate the molality of the solution and use it to calculate the boiling point of the same solution.

Δt(freezing) = m * Cf ⇒ m = Δt / Cf = 4.53 °C / 5.12 °Ckg/mol = 0.885 mol/kg

Δt(boiling) = m * Cb = 0.885 mol/kg * 2.52 °Ckg/mol = 2.23 °C

t (boiling) = 80.10 °C + 2.23 °C = 82.33 °C

The amine will remain in the upper organic (ethyl acetate) layer, while the phenol and the carboxylic acid will be in the lower aqueous layer. Effectively, a separation of amine will be achieved using basic extraction technique.

Sodium hydroxide (NaOH) makes a basic solution when dissolved in water. It will react with the acidic components of the analyzed mixture during extraction. Amine is also basic, so it will not interact with sodium hydroxide and will remain in the organic layer. Carboxylic acid is, as the name implies, acidic, and thus will be neutralized by sodium hydroxide, forming a water-soluble sodium carboxylate salt, which means that it will be removed from the organic layer. Phenol is also acidic enough to be neutralized by sodium hydroxide, so it will also form a water-soluble salt (sodium phenoxide) and be removed from the organic layer.

Explanation: When an element X is written in the form of X-N, N will the atomic mass of that element. So we have copper with a mass of 63 and 65. We are given percentages of each one. 69.17/100 of the copper atoms will be of weight 63 while 30.83/100 will be of weight 65. Keep in mind that amu does not actually mean weight but I'm just using it as a tool to help explain the general concept. Assume you have 100 copper atoms, and you need to find the average atomic mass for them, if you do this you will solve the problem. Due to the fractions, 69.17 of them will be 63 amu and the rest will be 65. So do 69.17*63+65*30.83 and divide by one hundred. By doing this you will get 63.6166.

the alkoxide group on chymotrypsin that attacks the carbonyl oxygen of the peptide bond of the substrate arises from which active-site amino acid side chain?

Answers

The alkoxide group responsible for the nucleophilic attack on the carbonyl group (more precisely the carbon atom) during peptide bond cleavage in chymotrypsin belongs to the serine 195 side-chain.

Because only serine and threonine of all the amino acids contain hydroxy-groups, only they qualify as possible answers. When we look at the structure of the chymotrypsin, we can see that there is a serine 195, so it must be it. Indeed, during peptide bond cleavage, histidine 57 side-chain deprotonates the serine 195 side chain, turning into a nucleophilic hydroxy-group, which can then attack the carbonyl group, held in place by the glycine 193's residue.

Stearic acid, palmitic acid, myristic acid, and lauric acid are examples of typical dietary saturated fatty acids.

Each carbon molecule in saturated fat is bonded to hydrogen, or "saturated," as a result of which the molecules are stable when the fat is cooked. As a result, heat won't cause them to oxidize or go rancid. The finest fats to use while cooking at temperatures above 180°C are saturated fats.

Unsaturated fats, which are liquid at room temperature, are regarded as healthy fats because they have a range of positive effects on health, including lower blood cholesterol levels, less inflammation, stable cardiac rhythms, and more.

The more polyunsaturated a fat is, the quicker it will oxidize since unsaturated fats are more prone to oxidation than saturated fats. Due to the more brittle double bonds, which permit more oxygen to react at those sites, this has occurred.

The products of the chemical reaction are sodium hydroxide and acetone. This is because acetone undergoes aldol condensation. Synthetic reactions occur when two or more reactants combine to form a single product.

Sodium hydroxide is completely ionic and contains sodium and hydroxide ions. The hydroxide ion makes sodium hydroxide a strong base and reacts with acids to form the corresponding salts with water. The chemical formula for acetone is CH32CO. Also known as propanone or dimethyl ketone, it is the smallest and simplest ketone. It forms an iodoform when it reacts with iodine in the presence of NaOH. Thus it can be seen that iodoform is formed in the presence of NaOH.

Answers

The molar mass of the triprotic acid used is 186.4 g/mol.

To calculate the amount of triprotic acid, we must first calculate the number of moles (n) of sodium hydroxide (NaOH) expended during the titration. To do this, we can use its molarity (c = 0.1063 M) and volume (V = 19.74 mL = 0.01974 L):

c = n/V ⇒ n = c*V

n(NaOH) = 0.1063 M * 0.01974 L

n(NaOH) = 0.0021 mol

Because 1 mol of a triprotic acid requires 3 moles of sodium hydroxide to be neutralized, the amount of the acid in the 20.00 mL sample will be:

n(acid) = n(NaOH) / 3

n(acid) = 0.0021 mol / 3

n(acid) = 0.0007 mol

Now we use a proportion to calculate the amount of acid present in a 250.0 mL sample:

0.0007 mol : 20.00 mL = X : 250 mL

X = 0.0007 mol * 250.0 mL / 20.00 mL

X = 0.00875 mol

Finally, we use the mass (m) and the number of moles to calculate the molar mass (M):

n = m/M ⇒ M = m/n

M = 1.631 g / 0.00875 mol

M = 186.4 g/mol

Moon, how would the gravitational force between Earth and the
astronaut change? How would the gravitational force between the Moon
and the astronaut change?

Answers

Gravitational force between the moon and the astronaut change are decrease

The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them

We can visualize the effect mathematically via the equation for newton's law of gravitation

Fgrav = Gm₁m₂/r₂

Fgrav is the magnitude of the gravitational force, in N between two objects G is the  gravitational constant means equal to 6.674×10⁻¹¹ N×m²/kg²m₁ and m ₂ are the masses, in kg of the two objects r is the distance in m between the two objects

From this relationship, we can see that force Fgrav and square of the distance rare inversely proportional as one increases the other decreases

Therefore, as the distance between the astronaut and earth increases, the magnitude of the gravitational force will decrease
