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

Answer:
x=5
Step-by-step explanation:
2x+2-7=5
2x-5=5
2x=10
x=5
Temperature = 4 - 5 = -1°C
<span>h = 0 when it hits the ground, therefore:
-16t^2 + 48t = 0
--------------------------------------...
Factor out -16t
-16t(t + 3) = 0
:
Two solutions
t = 0, when it begins it's upward journey
and
t = 3 sec, when it returns to earth
