Question

enthalpy Of combustion of Carbon to CO2 is -393.5kJ/mole.Calculate the heat released upon the formation of 35.2g of Co2 from carbon and dioxygen gas
​

Answer 1

Answer:

-315kjmol^-1

Explanation:

We know that,

C(s)+o2(g)=CO2 (g)

∆H=-393.5kJmol^-1

Heat released on formation of 44g or 1 mole CO2=-393.5KJmol^-1

Heat released on formation of 35.2g of CO2 is =-393.5×35.2/44

On solving we get=-315kJmol^-1
