Into a 10 dm capacity vessel was introduced 2 dm of hydrogen at a pressure of 1.01 x 109 Nm?; 3 dm' of hydrogen sulphide at a
pressure of 2.02 x 10% Nm? and 5 dm of chlorine at a pressure of
3.03 x 10 Nm? What is the total pressure of the vessel?

How many atoms are there in 5.70 mol of mg

Define the kinetic molecular theory

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
