Right balanced chemical equations, complete ionic equations, and net ionic equations for the reactants below. Include a description of what you did while going through your solving. 1. HgI2+PbSO4

2. Sodium carbonate and calcium react in a single replacement, one of the resulting products immediately decomposes. (you should end up with one balanced equation - 3 product)

3. CaS + Al

Write a net ionic equation to show that hydrofluoric acid, behaves as an acid in water.

The reaction q+r2=r2q is found to be first order in r2 and

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
