Answer:Heat is a type of ENERGY. When absorbed by a substance, heat causes inter-particle bonds to weaken and break which leads to a change of state (solid to liquid for example). Heat causing a phase change is NOT sufficient to cause an increase in temperature.
Explanation:
One mole of CS₂ and two moles of H₂S are formed as products and 3 moles of CH₄ are leftover.
<h3>What is the limiting reagent?</h3>
A limiting reagent is a reactant that is fully exhausted from the reaction mixture at the completion of a reaction. The limiting reactant will decide the maximum amount of product.
Given, a balanced chemical equation of the reaction between methane and sulphur is:

Given, the number of moles of the sulphur = 4
The number of moles of methane = 4
From the chemical reaction, one mole of methane reacts with four moles of sulphur. Therefore, four moles of sulphur fully react with one mole of methane and three moles of methane leftover.
