The weight of `CO_(2)` obtained by heating 2 g calcium carbonate will be

Options

A. `0.88 g `
B. `1.88 g`
C. `2.0 g`
D. `1.5 g `

Answer

B

Explanation

`underset(100) ( Ca CO _(3)) overset("Heat") to underset(44) (CaO ) + CO _(2)`
100 g `CaCO _(3)` liberated `CO_(2) = 44 g`
`2 g Ca CO_(3) ` liberated `CO _(2) = ( 44 xx 2)/(100) `
`= (88)/(100) = 0.88 g `
