The reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms. In order to follow the conservation of matter, the products of the chemical equation will have

Answers

Answer:

The same amount of atoms (3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms).

Explanation:

According to the law of conservation of mass, when a chemical reaction takes place there is no synthesis or degradation of matter, that is, matter can be neither created nor destroyed. It can only be transformed.

Therefore, in a chemical reaction the atoms are conserved. That means that the elements that in definite proportions are forming a compound, will reorganize to form new compounds, and the amount and type of atoms of the products will be the same as the reactants.

In summary, if the reactants in a chemical equation have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms, the products of the chemical equation will have 3 carbon atoms, 6 oxygen atoms, and 4 hydrogen atoms as well.

0.04 atm
O
400 atm
25 atm
52 atm​

Answers

Answer:

The answer is 25 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{2 \times 99.9}{8} = \frac{199.8}{8} \\ = 24.975[/tex]

We have the final answer as

25 atm

a sample of carbon dioxide gas occupies a volume of 20 L at standard temperature and pressure (STP). what will be the volume of a sample of argon gas that has the same number of moles and but tripled the absolute temperature?​

Answers

Volume of Argon = 59.972 L

Further explanation

In general, the gas equation can be written  

[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

At STP(0 C, 1 atm), 1 mol gas= 22.4 L

so for 20 L

[tex]\tt \dfrac{20}{22.4}=0.893[/tex]

For Argon

P = 1 atm

T = 273 K x 3 =819 K (tripled)

n = 0.893 (the same number of moles)

R = 0.082 L/atm.mol K

[tex]\tt V=\dfrac{nRT}{P}=\dfrac{0.893\times 0.082\times 819}{1}=59.972~L[/tex]

Two sphericle objects have masses of 8000 KG and 1500 KG their centers are separated by a distance of 1.5 M find the gravitational attraction between them

Answers

if I am correct I think its I'm am not 100 percent sure but I think this should be the answer

The gravitational force of attraction between them is 3.56 * 10⁻⁴ N

Using the formula of gravitational attraction

F = G*M1M2/d²

where G = 6.67 * 10⁻¹¹ Nm²Kg⁻²

M1 = 8000Kg

M2 = 1500 Kg

F =  6.67 * 10⁻¹¹ * 8000 * 1500 / (1.5)²

F = 3.56 * 10⁻⁴ N

If I place a balloon in my fridge that initially has a pressure of 1.02 atm and a
temperature of 11.2 °C, what will be the pressure (in atm) of the balloon when it is
fully cooled to 4.00°C by my refrigerator?

Answers

Answer:

P₂ = 0.99 atm

Explanation:

Given data:

Initial pressure = 1.02 atm

Initial temperature = 11.2°C

Final pressure = ?

Final temperature = 4.00°C

Solution:

Initial temperature = 11.2°C (11.2+273 = 284.2 K)

Final temperature = 4.00°C (4.00+273 = 277 K)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.02 atm / 284.2 K = P₂/277 K

P₂ = 1.02 atm × 277 K / 284.2 K

P₂ = 282.54 atm. K /293 K

P₂ = 0.99 atm

If a compound begins with a metal, it most likely is a _______ compound

metallic

molecular

covalent

ionic

Answers

Answer:

A

Explanation:

If a compound begins with metal, it is most likely to be a metallic compound. Thus, option A is correct.

The metallic compound has been formed when the metal has been bonded with a metal or more than 1 metal by the ionic or covalent interaction.

The ionic interactions result in between the metal and non-metal or between two metals, and the covalent interactions have been found in the nonmetals.

The molecular compound has been the one that has been formed a molecule. All the compounds are molecular compounds.

Thus, if it starts with metal, it has been most likely to form a metallic compound. Thus, option A is correct.

How many moles of cesium carbonate will be produced when 5.34 moles of cesium reacts with iron (III) carbonate? (You must write and balance the formula equation!)

Answers

Answer:

2.67 moles of cesium carbonate (Cs2CO3).

Explanation:

We'll begin by writing the equation for the reaction. This is illustrated below:

Cs + Fe2(CO3)3 —> Cs2CO3 + Fe

The above equation can be balance as follow:

There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by putting 2 in front of Fe as shown below:

Cs + Fe2(CO3)3 —> Cs2CO3 + 2Fe

There are 3 atoms of C on the left side and 1 atom on the right side. It can be balance by 3 in front of Cs2CO3 as shown below:

Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe

There are 6 atoms of Cs on the right side and 1 atom on the left. It can be balance by putting 6 in front of Cs as shown below:

6Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe

Thus, the equation is balanced.

From the balanced equation above,

6 moles of Cs reacted with 1 mole of Fe2(CO3)3 to produce 3 moles of Cs2CO3.

Finally, we shall determine the moles of cesium carbonate (Cs2CO3) produced by the reaction of 5.34 moles of cesium (Cs). This can be obtained as follow:

From the balanced equation above,

6 moles of Cs reacted to produce 3 moles of Cs2CO3.

Therefore,

5.34 moles of Cs will react to produce = (5.34 × 3)/6 = 2.67 moles of Cs2CO3.

Thus, 2.67 moles of cesium carbonate (Cs2CO3) were produced from the reaction.

a cube has a length of 1.02 cm and a mass of .001012 kg what is its density ​

Answers

Answer:

d = 9.5× 10⁻⁴ Kg/cm³

Explanation:

Given data:

Length of cube = 1.02 cm

Mass of cube = 0.001012 Kg

Density of cube = ?

Solution:

The length , height and width of cube is always same. Thus the volume of cube is,

Volume = length × height× width

Volume = 1.02 cm × 1.02 cm × 1.02 cm

Volume = 1.06 cm³

Density of cube:

d = 0.001012 Kg /1.06 cm³

d = 9.5× 10⁻⁴ Kg/cm³
