Answer:
0.333 mol NH₃
Explanation:
N₂ + 3 H₂ ⇆ 2 NH₃
This is the reaction that produces NH₃. Use the mole ratios to solve. For every 3 moles of H₂ that are consumed, 2 moles of NH₃ are produced.
(0.500 mol H₂) × (2 mol NH₃/3 mol H₂) = 0.333 mol NH₃
You will produce 0.333 moles of NH₃.
It might calculate the volume, but you need the length as well, depending on the object.
Liquid molecules forming a gas and gas molecule forming a liquid are equal in number.
First, we need to assume acetylene to adapt an ideal gas behavior. So, we can use the Ideal Gas Law:
PV = nRT
Given:
V = 42 L
T = 305 K
P = 780 torr = 1.026 atm
R = gas constant, 0.0821 L atm/ mol K
n = amount of gas in the canister
1.026 atm * 42 L = n * 0.0821 L atm/mol K * 305 K
n = 1.72 moles of gas
Yes, she is right. 1: when she took them out of the freezer heat was added. 2: when she toasted them in the oven heat was added and a chemical change occurred because the baking soda/powder reacted, causing the muffins to rise.
