<h3>What are decomposition reactions?</h3>
- Decomposition reactions are type of reactions in which a compound is broken down into two or more products.
- When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
- When this happens the soluble compound such as ionic compounds ionizes to form ions.
- This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
- For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.
Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

<u>Answer:</u>
It is the expression of Charles' Law.
<u>Explanation:</u>
The given expression V1T2 = V2T1 is the formula for the Charles' Law.
A special case of an ideal gas is named as the Charles' Law. This law applies to ideal gases only which are at constant pressure.
According to this law, the volume of a fixed mass of a gas is directly proportional to its temperature and is given by:
V1T2 = V2T1
Answer:
1.3 × 10³ cm³
Explanation:
The gas occupies a volume of V₁ = 310 cm³ under standard temperature and pressure (STP), that is, T₁ = 273.15 K and P₁ = 1.0 atm. In order to find the volume V₂ under different conditions we can use the combined gas law formula.
