Question

How many kg of carbon dioxide are used per year to produce their arm and hammer baking soda?

Answer 1

The complete question would be as follows:

700,000 tons of baking soda are produced per year. How many kilograms of carbon dioxide are used per year to produce baking soda?

We calculate as follows:

CO2(g) + NH3(aq) + NaCl(aq) + H2O -----> NaHCO3(s) + NH4Cl(aq)

700000 tons NaHCO3 ( 907.185 kg / 1 ton ) (1 kmole NaHCO3 / 84.0 kg NaHCO3) x (1 kmole CO2 / 1 kmole NaHCO3) x (44.0 kg CO2 / 1 kmole) = 3x10^8 kg CO2

Hope this answers the question. Have a nice day.
