1.0 g of magnesium is burnt with 0.56 g `O_(2)` in a closed vessel. Which reactant is left in excess and how much?

A

Mg, 0.44 g

B

`O_(2), 0.28g `

C

`Mg,0.16 g`

D

`O_(2),0.16g`

Text Solution

Verified by Experts

The correct Answer is:
C
24 g Mg requires 16 g oxygen
`therefore` 0.56g oxygen requires 0.84 g Mg
`therefore ` Mg left = 0.16 g
