Answer:3O2 + 4NH3 ---> 2N2 + 6H2O.
Explanation:
Let me give you (c) as an example: If you start out with 4.5 mol O2, assuming you want to completely react all the oxygen you'd need to add how much ammonia? The ratio of moles of O2 versus moles of NH3 is
(moles NH3) / (moles O2) = 4/3, or in other words,
moles NH3 = (4/3) x moles O2.
Therefore you need to add (4/3) x (4.5 moles) = 6 moles NH3.
The question says it want you to calculate the numbers of moles of all products and reactants for each case. So, that makes
(c) 4.5 moles [O2] + 6 moles [NH3] -------> 3 moles [N2] + 9 moles [H2O].
You need to do the same for (a) and (b)
===================================
2) The balanced net reaction is:
Mg + 2HCl -------> MgCl2 + H2
According to this reaction, 2 moles of HCl are consumed for every mole of Mg added.

Answer:
Past progressive and Simple past tense
Explanation:
The Past progressive tense shows ongoing activity, something that was occurring at a point in past. In the sentence, "While my mom and i were setting up the tent, my father stared the campfire." , "setting up the tent" shows past progressive tense.
Simple past tense indicates the action that has been completed in the past. In the given sentence, :my father started the campfire" is an example of simple past tense.
