In Experiment 1 you will be mixing two solutions from a number of ionic solutions. You will be required to carefully observe the changes that occur and record the appearance of any precipitates that form on mixing. Later you will be required to write the equations that correspond with the formation of any solid. This will require you to balance equations, an essential skill for chemists. Which of the following alternatives shows the correct stoichiometric coefficients indicated by the pronumerals, w,x,y,z, for the following precipitation reaction:
