How hydrogen peroxide can decompose to oxygen and water
Hydrogen peroxide can decompose to oxygen and water by the following reaction:
2 H2O(l) ------> 2 H2O(l)+ O2(g) ΔH= -196kJ
Determine the value of q(heat) when the 5.00 g of H2O2(l) decomposes at constant pressure.

Assume that the specific heat of the rocks is 0.082 J/ g-K Large beds of rocks are used in some solar heated homes to store heat.
Determine the percentage ionization of 0.0075M butanoic acid.(Ka=0.000015) and also determine the percentage ionization of 0.0075 M butanoic acid which is also 0.050 M in sodium butanoate.
Current crime reports indicate that 4.3 motor vehicle thefts take place each minute in the United States. Assume that the distribution of thefts per minute can be approximated by the Poisson probability distribution.
