Endothermic reaction equilibrium:

Question

BiCl3(aq) + H2O(g) = BiOCl(s) +2HCL(aq) + 2 HCl at a point at which the sollution is colorless and a small minute amoount of BiOCl(s) is observed.
for the folowing questions 1to 5:
a. state which way the reaction shift in terms of LeChateliers explain why
b. state what would be observed
stress imposed on the system
1. water vapor is added
2. a few drops of concentrated HCl is added to the system from part a my answer is it will shift to the right
3. a few drops of concentrated NaOH is added to the system in part b my answer is it will shift to the right
4. heat is added to the original reaction my answer is since heat is added to the reactants the equilibrium will shift to the product.
5. more BiOCl is added to the reaction my answer is it will shift to reactant side
pls correct my answers only i really don't know what to observe based on that reaction. this is a prelab question before we have the experiment thanks for any help you can give
