Hi there, we are told that this is a single displacement reaction.
00:06
In a single displacement reaction, we have a compound reacting with an element.
00:14
And what happens is the element replaces one of the elements in the compound.
00:19
So if x is a metal, it's going to replace the cation, which is also a metal, in the ionic compound.
00:25
So that would give us xb plus a.
00:30
Okay, so this is the general pattern for a single displacement.
00:34
Let's go ahead and look at our specific example here.
00:39
We have silver nitrate, heno3.
00:45
It is reacting with aluminum.
00:50
So aluminum is going to replace the silver.
00:54
So we need to write aluminum with nitrate.
00:57
But aluminum is from group 3 on the periodic table...
