Answer: 6 moles
Take a look at the balanced chemical equation for this synthesis reaction
N 2(g] + 3 H 2(g] → 2 NH 3(g]
Notice that you have a 1:3 mole ratio between nitrogen gas and hydrogen gas. This means that, regardless of how many moles of nitrogen gas you have, the reaction will always consume twice as many moles of hydrogen gas.
So, if you have 2 moles of nitrogen taking part in the reaction, you will need
2 moles N 2 ⋅ 3 moles H 2 /1 mole N 2 = 6 moles H 2
Answer: Mixtures do not have the same composition, properties, and appearance throughout.
Explanation: It does not vary from sample to sample.
Answer:
because he would've not known properly about it!
The answer is lower. when there’s a lower temperature the molecules will be moving at a lower speed. a lower speed means less thermal energy.
Answer is: BaCO₃ (barium carbonate).
barium carbonate is white powder with low solubility in water, but good solubility in acids (<span>with the exception of sulfuric acid), because it forms solunle salts and carbonic acid (decomposes on carbon(IV) oxide and water).
For example if we add hydrochloric acid in barium carbonate:
BaCO</span>₃(s) + 2HCl(aq) → BaCl₂(aq) + H₂CO₃(aq).
