Question:
In a class experiment 5.0 of ethanol (CH3CH2OH) was completely burnt and all the heat evolved was used to heat 500cm3 of water from 200C to 800C. Given that the specific heat capacity of water is 4.2j/g/k and the density of water is 1g/cm3.
(i) Write the equation to show the reaction that takes place when ethanol is burnt ( 1 mk)
(ii) Calculate the heat energy observed by water ( 2 mks)
(iii) Find the molar heat of combustion of ethanol ( 1 mk)
C= 12 (H= 1) (O= 16)
