Consider the balanced equation: N₂H₄ + 2 H₂O₂ → N₂ + 4 H₂O What are the mole ratios of hydrazine (N₂H₄) to hydrogen peroxide (H₂O₂) and hydrazine (N₂H₄) to water (H₂O)?

A. 1:2 and 1:4
B. 1:3 and 1:4
C. 1:2 and 3:5
D. 1:3 and 3:5

The answer is A, 1:2 and 1:4

Explanation:

This can be derived from looking at the balanced chemical equation. Notice the coefficients in front of each reactant and product. These show the mole ratios of each compound necessary to form the balanced equation.

N₂H₄ does not have a coefficient, which automatically becomes 1. H₂O₂ has a coefficient of 2, making the ratio between the two 1:2. H₂O has a coefficient of 4 making the ratio between hydrazine and water 1:4. Hope this helps!

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
