Answer:
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. ... Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

A gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C. Details about temperature can be found below.
<h3>How to calculate temperature?</h3>
The temperature of a gas can be calculated using the following formula:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- R = gas law constant
- T = temperature
0.755 × 4.31 = 1 × 0.0821 × T
3.25 = 0.0821T
T = 3.25 ÷ 0.0821
T = 39.58°C
Therefore, a gas that occupies 4.31 litres at a pressure of 0.755 atm will have a temperature of 39.58°C.

Answer:
No
Explanation:
The equation does not obey the law of conservation of mass by not accounting to the total number of Chlorine in the products.
Law of conservation of mass states that in ordinary chemical reactions, matter can neither be created nor destroyed but can be converted from one form to another.
The equation presented was
CuCl₂ + Na₂S → CuS + NaCl
1. The total number of copper in the reactant is equal to number of Cu in product
2. Numbe of Chlorine in the reactant is 2 while in the product is just 1. Not accounted for.
3. Number of sodium on the reactant is not equal to number of sodium on the product I.e 2 on the reactant and just 1 on the product.
4. Number of sulfur on the reactant is equal to number of sodium on the product.
Correct chemical equation
CuCl₂ + Na₂S → CuS + 2NaCl
Lions walk on 4 legs, humans walk on 2. female lions live in groups but are taken over by groups of male lions from time to time, human adults tend to live alone or in pairs with their offspring. Humans can talk and lions cannot. lions have manes around the face.
The formula is:
Zn + Hcl —> H2 +Zncl2
Hence, the 2 products formed are:
Hydrogen gas and salt
