when heated, sodium bicarbonate, NaHCO3, decomposes into sodium carbonate, Na2CO3, water, and carbon dioxide. If 5.00 g of NaHCO3 decomposes what is the mass of the carbon dioxide produced?

not to big of a help

1.3g

1.456 g CO2

To find the mass of carbon dioxide produced when 5.00 g of NaHCO3 decomposes, you need to determine the stoichiometry of the reaction between NaHCO3 and carbon dioxide.

The balanced chemical equation for the decomposition of sodium bicarbonate is:

2 NaHCO3(s) → Na2CO3(s) + H2O(g) + CO2(g)

From the balanced equation, we can see that for every 2 moles of NaHCO3, 1 mole of CO2 is produced.

To calculate the mass of CO2 produced, you can follow these steps:

1. Convert the given mass of NaHCO3 to moles using its molar mass. The molar mass of NaHCO3 is calculated as follows:
(1 Na atomic mass) + (1 H atomic mass) + (3 O atomic mass) + (12 C atomic mass) + (16 O atomic mass) = 23 + 1 + 48 + 12 + 16 = 100 g/mol.

Moles of NaHCO3 = Mass of NaHCO3 (g) / Molar mass of NaHCO3 (g/mol).
Moles of NaHCO3 = 5.00 g / 100 g/mol = 0.05 mol.

2. Use the mole ratio from the balanced equation to determine the number of moles of CO2 produced. From the balanced equation, we know that for every 2 moles of NaHCO3, 1 mole of CO2 is produced.
Moles of CO2 = Moles of NaHCO3 / 2 = 0.05 mol / 2 = 0.025 mol.

3. Finally, calculate the mass of CO2 produced by multiplying the number of moles of CO2 by its molar mass. The molar mass of CO2 is calculated as follows:
(1 C atomic mass) + (2 O atomic mass) = 12 + 32 = 44 g/mol.

Mass of CO2 = Moles of CO2 (mol) * Molar mass of CO2 (g/mol) = 0.025 mol * 44 g/mol = 1.1 g.

Therefore, when 5.00 g of NaHCO3 decomposes, the mass of carbon dioxide produced is 1.1 g.

Write and balance the equation.

2NaHCO3 ==> Na2CO3 + 2CO2 + H2O
Check my balancing.

Convert 5.00 g NaHCO3 to moles. moles = grams/molar mass.

Using the coefficients in the balanced equation, convert moles NaHCO3 to moles CO2.

Now convert moles CO2 to grams. g = moles x molar mass
