To determine the mole ratios of the substances, we need to know the balanced chemical reaction of the system. The reaction between hydrazine and hydrogen peroxide yields to nitrogen and water. The balanced chemical reaction is:
N2H4 + 2H2O2 --> N2 + 4H2O
Therefore, the mole ratio between hydrazine and hydrogen peroxide is 1:2 and the mole ratio between hydrazine and water is 1:4.
The answer is caves.. i think
Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.
The answer is 14.22 mg / (mm^2)
All of the above. If you are going to narrow it down, it would be high voltage and radioactivity.
