Calculate the amount of `CO_(2(g))` produced by combustion of 32 g of oxygen.

Options

A. 22 g
B. 240 g
C. 21g
D. 32 g

Answer

A

Explanation

The balanced equation is :
` CH_(4 (g)) + 2O_(2(g)) to CO_(2(g)) + H_(2) O_((g))`
`implies ` 2 moles or 64 g of `O_2` gives 44 g of `CO_2`
` therefore ` 32 g `O_2` will produce 22 g of `CO_2`.
