An environmental chemist sampling industrial exhaust gases from a coal-burning plant collects a CO2-SO2-H2O mixture in a 21-L steel tank until the pressure reaches 850 torr at 45oC.
a) How many moles of gas are collected?
b) If the SO2 concentration in the mixture is 7.95 x 103 parts per million by volume (ppvm), what is its partial pressure?
The activation energy of a reaction is the difference between the energy states of reactants and the products
Calculate the amount of heat [kcal] released when 50.0 g of steam at 100 °C hits the skin, condenses, and cools to a body temperature of 37 °C.
