Enthalpy of combustion of carbon to CO(2...

Enthalpy of combustion of carbon to `CO_(2)` is `-393.5 kJ mol^(-1).` Calculate the heat released upon formation of 35.2 g of `CO_(2)` from carbon and dioxygen gas.

Text Solution

Verified by Experts

`C_((s))+O_(2(g)) to CO_(2(g)) " "triangleH="-393.5kJ/mole"`
44 gms of `CO_2 to -393.5kJ`
35.2 gms of `CO_2 to ?`
`(35.2 xx 393.5)/(44)=-314.8kJ`
