Answer:What happens to the temperature of a substance during a phase change? Why does this happen?
Explanation:During a phase change the temperature remains constant. This is because the heat supplied to change the state of matter is used in breaking the intermolecular forces and other attractive forces. Therefore, the temperature remains constant as no heat is absorbed or released.
Atomic mass? I'm not shre
The moles of water that are produced from 373 moles of ammonia present in any chemical reaction is 746 moles.
<h3>What is the stoichiometry?</h3>
Stoichiometry of the reaction gives idea about the amount of entities present in any chemical reaction before and after the reaction.
Given chemical reaction is:
3Al + 3NH₄ClO₄ → Al₂O₃ + AlCl₃ + 3NO + 6H₂O
From the stoichiometry of the reaction it is clear that:
3 moles of Al = produces 6 moles of H₂O
373 moles of Al = produces 6/3×373 = 746 moles of H₂O
Hence required moles of water is 746 moles.
