Question

How many grams of carbon dixoide will be produced if 135 grams of ZnO is completley reacted

Answer 1

We know that carbon will react with zinc oxide to produce zinc and carbon dioxide. So, first we must write the balanced equation:

`C+2ZnO\to CO_2+2Zn`

Now, knowing that 135 grams of ZnO reacted and using that:

- 1 mol of ZnO: 81.41 grams of ZnO

- 1 mol of CO2: 2 mol of ZnO

- 1 mol of CO2: 44.01 grams of CO2

Writing it as a table,

Answer:

36.5 g of CO2 will be produced
