Potassium chlorate on heating decomposes as follows: 2KClO3(s) → 2KCl(s) + 3O2(g)

Assuming 100% yield, calculate the mass of oxygen formed when 3.28 g of potassium chlorate is heated.

Select one:
A. 0.856 g
B. 2.57 g
C. 1.93 g
D. 1.28 g

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.
