In a endothermic and exothermic experiment, why would the specific heat be the same for all...
Homework Answers
1 ) since specific heat is heat required to raise temperature of unit mass substance through one degree.
It is an intensive property ( non - additive ) so it has always constant value.
2 ) reason for different value of enthalpy
( a ) molecules having resonance.
( b ) molecules having more than one bond of similar types so average bond energy differ from actual value.

Experiment 5: Last week, you set up and observed an endothermic and two exothermic reactions in aqueous solution. These reactions yielded solid, aqueous, or gaseous products. This week, you will conduct two different gas-producing reactions and use the corresponding flammable products in a combustion reaction to propel a mini-rocket. In all chemical reactions, it is important to first write a balanced chemical equation to predict the relative reactant amounts needed to make the amount of desired product and achieve the...

In an experiment to measure the specific heat capacity of aluminium, identical size copper and aluminium blocks were alternately placed in an insulated calorimeter and heated by an electrical heater. The electrical heater supplied an identical energy E to the metal blocks. It was assumed that the heat loss (h) from both calorimeter measurements was identical. The measured masses were 530 g for the aluminium block and 1700 g for the copper block. The temperature rises were 15.3oC for the...
