Please review this model chemical reaction: A + 2B ---> C + 4D

Which of the above represents the reactants? Select ALL correct responses, below.

a
C
b
A
c
C + 4D
d
2B

The correct responses for the reactants in the given chemical reaction are:

A
2B

The reactants in the given chemical reaction are:

- A
- 2B

So the correct responses are:

a) A
d) 2B

To identify the reactants in the chemical reaction A + 2B ---> C + 4D, we need to understand the basic structure of a chemical reaction.

In a chemical reaction, reactants are the substances that undergo a chemical change to form new substances called products. Reactants are usually written on the left side of the arrow (-->), whereas products are written on the right side.

Looking at the given equation, we can see that there are four substances mentioned:

A, 2B, C, and 4D

To determine which of these substances are reactants, we need to consider the left side of the arrow. In this case, the reactants are A and 2B. So, the correct responses are:

a - A
b - 2B
