The Haber Process converts hydrogen and nitrogen into ammonia in the following exothermic reaction: 3H2+N2=2NH3. Explain the effect of increasing the pressure and why.

According to Le Chatlier's Principle, an increase in pressure favours the side with the least moles, which in this case is the forward reaction. Hence, increasing the pressure would result in an increase in ...

16.4 g of Ca(OH)2 was reacted with HCl in a reaction. What was the expected mass of CaCl2, given the mass of the reactant Ca(OH)2 was 12.6 g? What is the percentage yield of the reaction? ( Give all answers to 3 significant figures)

Ca(OH) 2 :Mass = 12.6 g Molar mass= 40.1 + (16 x 2) + (1 x 2) = 74.1 g/molMoles = Mass / Molar mass = 12.6 g / 74.1 g/mol = 0.17 molThe molar ratio is 1:1 of Ca(OH) 2 : CaCl 2 . ( 1 molecule of Ca(OH) 2 reac...
