Hi there.
00:04
In this question, we are reacting an acid with a variety of compounds here, and we want to know which one will not form carbon dioxide and water.
00:13
Well, an acid has the general form h .a, where h is the hydrogen ion, and a represents the anion.
00:23
When this is reacted with a metal carbonate, so i'm just going to use m to represent any metal, and co3 is carbonate, one of the products that are formed, is going to be hydrogen carbonate, or h2, co3.
00:43
And once h2 -c -o -3 is formed, it decomposes.
00:52
It immediately decomposes into h -2 and co2, carbon dioxide and water, in other words.
01:05
So the key here is we are looking for a compound that contains carbonates.
01:13
Because when they contain carbonates and an acid reacts with them, they will produce water and carbon dioxide, just like when we put baking soda and vinegar together.
01:24
All right, so let's look at our answer choices here...
