Given:
hydrazine (N2H4) to hydrogen peroxide (H2O2)
Find: mole ratio
Solution
the molar mass of hydrazine, N2H4 = 32 g/mol
the molar mass of hydrogen peroxide, H2O2 = 34 g/mol
mole ratio of hydrazine to hydrogen peroxide = 32g/mol / 34 g/mol = 16/17

I am pretty sure it is D.
All the other ones don't affect the second activity...
Hope I helped...

Answer:
(-6,2)
Step-by-step explanation:
<u>Substitution</u>
Substitute x = -6 from the first equation in the second equation.
Normally, we have to substitute either x-term or y-term in one of the equation to get another term. For this situation, we already know the value of x so It is not necessary to substitute the y-value.
<u>Answer</u><u> </u><u>Check</u>
We have to check the answer to make sure that we have got the right answer.
We can check the answer by substituting both x-value and y-value in the equation.
Substitute x = -6 and y = 2 in the equation.
The equation is true. Therefore, our answer is (-6,2)
