Uhhh, that looks like a game. I don't know how to tell u the answers for that thing -_-
Answer:

Explanation:
First reaction gives you the number of moles or the mass from Carbon and hydrogen
for carbon:


Analogously for hydrogen:
0.0310g
have 0.0034gH or 0.0034mol of H
In the second reaction you can obtain the amount of nitrogen as a percentage and find the mass of N in the first sample.

now

this is equivalet to 0.002mol of N
with this information you can find the mass of oxygen by matter conservation.

this is equivalent to 0.004molO
finally you divide all moles obtained between the smaller number of mole (this is mol of H)

and you can multiply by 5 to obtain: 
Produces heat, putting off air or bubbles and changes the smell or odor it changes the state that’s how you know it is a chemical reaction

thank you so much!!!!!!!!!!!!
