A. You've got to be kidding. I and others will be glad to try to explain some sticky point of chemistry, but I don't do your homework for you. If there is something you don't understand, like what a synthesis reaction is, then I'll be glad to explain that it is where two or more reactants combine to form a single product. But we won't do all of these for you. Check out page 6 on the North Carolina references tables. It contains some guidelines on equation writing. If this is standing in the way of you passing chemistry, then maybe you don't need to pass. Re-taking the course, might be your best option.

A. The names of your reactants have two words. Switch the first word in each name to get the name of the two new products. If you have to identify which of the new substances formed the precipitate, look for a compound that does not contain sodium or potassium (I don't see anything in your third equation that would form a precipitate). When a new substance forms that is "insoluble" in water, that means it "falls" out of solution as a precipitate and the solution looks cloudy. That's how you recognize the formation of a precipitate - the solution turns cloudy. I'll do the first reaction for you: Mercury(II)chloride plus sodium carbonate form sodium chloride and mercury(II) carbonate (the precipitate). If you need the equation using… [cont.]
