So in this question says to define oxidation and reduction.
00:03
So oxidation first starts is loss of electron.
00:15
2.
00:17
Increase an oxidation number.
00:21
Oxidation number.
00:24
3 is loss of hydrogen is gain of oxygen.
00:38
Okay.
00:39
Reduction is going to be opposite oxidation.
00:54
So you refer to how this the opposite of others.
01:00
So the follow -up question, this is number 1.
01:05
Number 1, a.
01:06
B says, write the overall balanced chemical equation for the reaction of zinc, which is going to be solid, plus hydrochloric acid, which would be acchus.
01:20
So that will produce zinc chloride plus hydrogen gas, and this is acous.
01:27
So this is going to be two...
