So i'm going to call my alkali metal m.
00:05
I'll write a general reaction of it reacting with the halogen.
00:09
Let's just take cl2.
00:13
So alkali metals like to have a plus one charge.
00:17
Halogens like to have a minus one charge.
00:19
So it's going to form mcl, right, plus one minus one neutral complex overall.
00:26
And now we just have to go about balancing this.
00:28
So we have two cl over here.
00:30
We need to make sure we have two over here as well.
00:33
We now have two metal, so we need a second metal here.
00:38
For water, it looks pretty similar, except we need to know what we're forming...
