Question

if I start with 2 moles of sodium bicarbonate, decomposition will produce 1 mole of sodium carbonate, 1 mole of water, and one mole of carbon dioxide. How many moles of water will be produced if you start with 4 mol of sodium bicarbonate

Answer 1

2 moles of water (H2O)

Step-by-step explanation:

First, we'll begin by writing a balanced equation for the decomposition of sodium bicarbonate. This is illustrated below:

2NaHCO3 —> Na2CO3 + H2O + CO2

We can obtain the number of moles of water (H2O) produced by decomposing 4 moles of NaHCO3 as follow:

From the balanced equation above,

2 moles of NaHCO3 produced 1 mole of H2O.

Therefore, 4 moles of NaHCO3 will produce = 4/2 = 2 moles of H2O.

From the calculations made above, we can see clearly that 4 moles of sodium bicarbonate (NaHCO3) will produce 2 moles of water (H2O)
