According to Balance chemical equation,
N₂ + 3 H₂ → 2 NH₃
1 mole of Nitrogen reacts with 3 moles of Hydrogen to produce 2 mole of Ammonia.
It is known that i mole of any gas at standard temperature and pressure occupies 22.4 L of Volume. So, we can also say,
22.4 L (1 × 22.4) of Nitrogen gas (in question it is taken in excess) reacts with 67.2 L (22.4 × 3) of Hydrogen gas to produce 44.8 L (22.4 × 2) of Ammonia.
Result:
44.8 L is the correct answer.
What do you need help on which problem
Answer:
i think it is b and a
Explanation:
because it gathers to gather but mass might change just because it it is dissolving. and phase change because it may not do anything
When delta H is negative, it means the products in the reaction have lower energy compared to the reactants, so the reaction has lost energy and released it as heat, making it exothermic.
