Given a gas whose temperature is 687 Kelvin, at a pressure of 40.0 kPa with a volume of 220 L. What is the pressure of the gas if its Temperature changes to 897 Kelvin and its Volume increases to 320 L?

How many miles of water are produced if 5.43 mol pbo2 are consumed

The rate constant for the reaction below is 6.2 x 10−5 mol l−1 s −1. if the initial concentration of a is 0.0500 m, what is its concentration after 115 s?

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.
