in each equation.
part a
balance the following equation, and then find the number of moles of nahco₃ that will generate 0.8 moles of co₂
nahco₃ - na₂co₃ + h₂o + co₂

Explanation:

Step1: Balance the chemical equation

$$2\text{NaHCO}_3 ightarrow\text{Na}_2\text{CO}_3+\text{H}_2\text{O}+\text{CO}_2$$

Step2: Determine the mole ratio

From the balanced equation, the mole ratio of $\text{NaHCO}_3$ to $\text{CO}_2$ is $2:1$.

Step3: Calculate the moles of $\text{NaHCO}_3$

Let $n$ be the moles of $\text{NaHCO}_3$. Using the mole ratio $\frac{n(\text{NaHCO}_3)}{n(\text{CO}_2)}=\frac{2}{1}$. Given $n(\text{CO}_2) = 0.8$ mol. Then $n(\text{NaHCO}_3)=2\times n(\text{CO}_2)$.

Answer:

$1.6$ moles
