how is silver chloride is an insoluble compound when silver is insoluble, but chloride is soluble? does just one element have to be insoluble for the whole compound to be insoluble??!?

THANKS IN ADVANCE!

I tried doing this problem but I guess I don't understand the concept.
Using the starting chemicals F, F2, CH4 or CH3 make up a free radical.

Initiation step:
propagation step:
Termination step;
You can use two of the radicals given then go through the steps. And please explain. Thanks for helping!

1) sodium nitrate decomposes upon heating to form sodium nitrate and oxygen gas. this reaction is sometimes used to produce small quantities of oxygen in the lab. how many grams of sodium nitrate must be heated to produce 128g of oxygen?

2) calculate the mass of silver chloride, AgCl, and dihydrogen monosulfide, H2S, formed when 85.6g of silver sulfide, Ag2S, reacts with excess hydrochloric acid, HCl

if you can explain how you got your answers, that would be great. thanks so much

I put one gallon of muric acid in my swiming pool 24x12x5 say 35 cubic yards. It was to assist in the removal of the calcium that had precipitated to the walls and floor of the pool. I now need to reduce the acidity. Hence the question about washing soda, if this can be used what sort of quantities would be needed.

I am working in the jewelry industry and was wondering how this reaction is working. We frequently clean tarnished silver with a bowl of water lined with aluminum foil, hot water, baking soda, a pinch of salt and a little dishwashing liquid. I have a little chemistry in my background and figure it is an oxidation/reduction reaction. I am curious to exactly what happens and how it is working. Also, are there any other effective methods for cleaning tarnished silver jewelry?
