All right, well, chemistry requires precision.

00:23

So to be a good chemist, we can't just take

00:26

a handful of this and a pinch of that and expect to get the result we want.

00:30

And the same thing goes for science lingo.

00:33

The words scientists use have precise meanings.

00:37

So with that, we can immediately rule out option A - supply

00:40

because it lacks that precision. Like, it could be anything.

00:43

The word "supply" isn't specific to materials involved in a chemical reaction.

00:47

We can also get rid of option C because the word "resultant"

00:50

isn't really a word used in chemistry.

00:53

But even so, we can tell that it wouldn't be right because

00:56

the question is about starting materials, not the result.

00:59

All right? All right. Well, D's out, too.

01:01

The product is what the chemical reaction produces.

01:05

It's what we end up with. The answer we're looking for is B - reactant.

01:09

Reactants are the starting materials of a chemical reaction.

01:13

Think of bread. Ingredients:

01:15

the water, the yeast, the flour, the salt.

01:18

Those are the reactants.

01:20

And when you put them together and add heat for a while,

01:22

the product is just a big fat loaf of yumminess. Yum. Bread.

01:28

All right, we just need to be careful not to eat all of our science

01:30

in one sitting. Otherwise, well, there could be a bad chemical reaction.

01:33

Yeah. Stomach ache. You don't wanna go there.
