What do you think is happening to the soda and air in the can?

Answers

Answer 1

The soda and air will bubble, increasing the chances of an explosion.

Carbonation in soda is made up of carbon dioxide or CO2 bubbles. Carbonated beverages are injected with this colorless and odorless gas under high pressure during manufacture until the liquid is supersaturated with gas. Individuals determined, at the discretion of the Federal Aviation Surgeon, to have a static or non-progressive disqualifying condition.

In soda ash, the dispersed phase is a gas and the dispersion medium is a liquid. Soda ash is an example of a gas that dissolves in a liquid. Shaking the can introduces many small air bubbles into the liquid, so the dissolved gas is more likely to combine with existing air bubbles and evaporate rather than form new air bubbles. By avoiding the difficult step of shaking and frothing the soda, the gas can escape faster creating more fizz.

Answers

Answer: 63.6166 amu (atomic mass units)

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.

Example: The products of a chemical reaction are Sodium Hydroxide and Acetone.
Without knowing the reactants, how do you know that this is not a synthesis reaction?

Answers

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.

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

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

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

Answers

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.

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.
