Second one. Roman "newspapers" were basically stone slabs, or metal. Chinese were paper. or some material like it.
I have 5 years experience in the food industry. Two of those years were in management. I’ve learned how to be a good listener when dealing with customers. Most problems can be solved with a sympathetic tone. Being in a fast paced environment helps you to be on your toes, and keeps you focused on doing your job in a fast and efficient way.
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.
Lying.
I believe that's what you're looking for ? If not you might need to explain what the directions want. (:

<span>One thing to
keep in mind as you write is that your readers may not have experienced what
you are writing about in the same capacity (if at all) as you have. As such, it is important to keep in mind that
in order to provide the best possible image for readers, you should try to
include descriptions that include as many sensory perceptions as possible. What that means is that you should include
details that include descriptions of sight, smell, sound, taste, and
touch. </span>
