Question

Part A If a diamond is burned in an oxygen containing atmosphere the carbon in the camond is converted to CO, How much CO, will be produced ita 04 (2 carat diamond is burned? Express your answer in grams to one significant figure

Answer 1

0.9 g of CO will be produced.

Step-by-step explanation:

A diamond is formed of C atoms. When it is burned, it undergoes a combustion reaction. If the product is CO the combustion is incomplete. The reaction is:

C(s) + 0.5 O₂(g) ⇄ CO(g)

A carat is a unit of weight for diamonds where 1 ct = 200 mg. So, we have 2 ct = 400 mg = 0.4 g of carbon.

In the balanced equation we can see that when 12 grams of C are burned, 28 grams of CO are formed. This is the stoichiometric relationship that we will use to find out the amount of CO formed when 0.4 g of carbon are burned:

`0.4gC.(28gCO)/(12gC) =0.9gCO`
