Hi there, in this question, what we essentially have is a double replacement reaction.
00:09
Or you might know them as a double displacement reaction.
00:17
In a double replacement reaction, we have two ionic compounds, ab plus x, y, and the ions are going to exchange.
00:28
So the positive ion from the first goes with the negative ion from the second, and the positive ion from the second goes with the negative ion from the first.
00:36
So our first compound in this is actually hcl.
00:42
I'm going to put the two ions together.
00:47
And the other compound is the calcium carbonate.
00:56
So these are going to exchange ions.
00:58
The hydrogen is going to go with the carbonate.
01:03
Hydrogen has a one plus charge, whereas carbonate has a two negative charge...
