Consider the following reaction: Mg  + Cu2+ –>  Mg2+ + Cu The species that lost electrons is:

Given the following reaction at equilibrium,  A + 3B  ↔  2C + 2D    ΔH = 20.91 kJ/mol The amount of C in the system can be increased by:

A 0.2 M solution of formic acid has a pH of 5.0.  What is its Ka value?

Butane burns in oxygen according to the following balanced equation: C4H10 + 13/2 O2  ↔  4CO2 + 5H2O If the butane is consumed at the rate of 1.50 L/s, the oxygen is consumed at the rate of:

C2H6 –> C2H2 + 2H2    ΔH = 319.92 kJ/mol. An alternate way to write this equation is:

11.4 mL of 0.7 M NaOH was used to titrate 5.0 mL hydrochloric acid.  What is the molarity of the acid?

In an endothermic reaction:

At a fixed temperature, H2(g), Cl2(g) and HCl(g) exist in equilibrium according to the equation: 2HCl(g) ↔ H2(g) + Cl2(g)         Ke = 0.040 In order to have 0.020 mol of Cl2(g) at equilibrium, how many moles of HCl(g) should be initially placed in an empty 1.0 L flask?
