A. +571.6 kJ
B. -571.6 kJ
C. -285.8 kJ
D. +285.8 kJ
Correct Answer:
Option C = -285.8 kJ
If the heat of combustion of hydrogen is -285.8kJ; What is the heat of formation of water?
![Ice of mass 10g at 5ºC was completely converted to water at 0ºC, calculate the quantity of heat used. [specific heat capacity of ice = 2.1 Jg-1K-1, specific latent heat of fusion of ice = 336 Jg‾¹]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png "Ice of mass 10g at 5ºC was completely converted to water at 0ºC, calculate the quantity of heat used.
