consider the balanced equation below.\nn₂h₄ + 2h₂o₂ → n₂ + 4h₂o\nwhat are the mole ratios of hydrazine (n₂h₄) to hydrogen peroxide (h₂o₂) and hydrazine to water?\no 1:2 and 1:4\no 1:3 and 1:4\no 1:2 and 3:5\no 1:3 and 3:5
Answer
Explanation:
Step1: Identify coefficients in equation
The balanced equation is $N_2H_4 + 2H_2O_2\rightarrow N_2+4H_2O$. The coefficient of $N_2H_4$ is 1, of $H_2O_2$ is 2 and of $H_2O$ is 4.
Step2: Calculate mole - ratios
The mole - ratio of $N_2H_4$ to $H_2O_2$ is $\frac{\text{coefficient of }N_2H_4}{\text{coefficient of }H_2O_2}=\frac{1}{2}=1:2$. The mole - ratio of $N_2H_4$ to $H_2O$ is $\frac{\text{coefficient of }N_2H_4}{\text{coefficient of }H_2O}=\frac{1}{4}=1:4$.
Answer:
A. 1:2 and 1:4
