When 90cm^3 of methane is burned, the heat produced is used to raise the temperature of 100 cm^3 of water from 20.0°C to 50.0C. Calculate the enthalpy change for the reaction.(adsbygoogle = window.adsbygoogle || []).push({});

I'm not getting the same answer as the textbook....Please tell me whether my method is correct

All you do here is use the formula mass x specific heat capacity x change in temp. So,

the enthalpy change would be -(100/1000) x (4.18) x (30) = -12.54 KJ ?
