How many moles of `CO_(2)` will be formed when a mixture containing 10 moles each of `Li_(2)CO_(3)` and `Na_(2)CO_(3)` are heated ?

Verified by Experts

On heating, `Li_(2)CO_(3)` decomposes to give `Li_(2)` and `CO_(2)` whereas `K_(2)CO_(3)` do not decompose.
`Li_(2)CO_(3)overset(Delta)rarr Li_(2)O+CO_(2)`
Since one mole of `Li_(2)CO_(3)` decomposes to give one mole of `CO_(2)`, 10 moles of `CO_(2)` will be formed on heating a mixture containing 10 moles each of `Li_(2)CO_(3)` and `Na_(2)CO_(3)`.

On heating a mixture containing 1 mole each of Li_(2) CO_(3) and K_(2)CO_(3) ……..is / are formed .

2 moles of `CO_2`

1 moles of `CO_2`

1.5 moles of `CO_2`

No carbon dioxide

On heating a mixture containing 1 mol each of Na_2CO_3 and Li_2CO_3,

2 mol of `CO_2` are formed

1 mol of `CO_2` is formed

1.5 mol of `CO_2` are formed

no`CO_2` is formed

One mole of CO_(2) contains

`6.02xx10^(23)" atoms of C"`

`6.02xx10^(23)" atoms of O"`

`18.1xx10^(23)" molecules of CO"_(2)`

`"3 g atoms of CO"_(2)`
