Question

how many grams of CO2 can be obtained by heating 1 mole sodium carbonate​

Answer 1

Answer:

because oxygen was burning and carbon is released

Answer 2

Given:

Heating of sodium carbonate.

To find:

We have to find the grams of carbon dioxide obtained.

Solution:

On heating, sodium carbonate produces sodium oxide along with carbon dioxide gas.

The balanced chemical equation is as follows-

$Na_2CO_3\rightarrow Na_2O+CO_2$

Thus one mole of sodium carbonate evolves one mole of carbon dioxide gas on heating.

The atomic weight of C is 12 and oxygen is 16 grams.

So, the molecular weight of carbon dioxide is 12+16×2=44 grams.

1 mole of carbon dioxide has 44 grams.

So, 44 grams of carbon dioxide is obtained.
