Make a characteristic of the substance, the formula of which is CO2, according to the plan: 1) qualitative composition; 2) quantitative composition; 3) the oxidation state of each element; 4) relative molecular and molar mass; 5) mass fraction of each element; 6) the ratio of the masses of the elements; 7) title.

1) qualitative composition – carbon, oxygen

2) quantitative composition – 1 carbon atom and 2 oxygen atoms

3) the oxidation state of each element is C (+4) O2 (-2)

4) relative molecular and molar mass – Mr (CO2) = 12 + 16 * 2 = 44

M (CO2) = 44 g / mol

5) mass fraction of each element –

w (C) = 12/44 = 0.27 or 27%

w (O) = 16 * 2/44 = 0.73 or 73%

6) the ratio of the masses of the elements

C = 12

O2 = 16 * 2 = 32

12: 32 = 6: 16

7) name Carbon monoxide 4
