Help please ;( really don’t understand Chemistry would really appreciate it if can explain to me thank you!
Tanya [424]

Answer:

b)   O₂

d)   CH₄

Explanation:

In a chemical equation, the <u>reactants</u> are the substances that are written on the <u>left side</u>. The reactants react to produce the products. On the right side, the products are written.

The arrow => is used to separate the reactants from the products.

To the left of the arrow, you can see this written:

CH₄ + 2O₂

The plus sign + is used to separate each reactant.

In 2O₂ you can ignore the big 2 because it is a coefficient, which is written to balance the equation.

The reactants are CH₄ and O₂

What volume of water is required to prepare 0.1 M H3PO4 from 100 ml of 0.5 M solution?
ExtremeBDS [4]

Answer: A volume of 500 mL water is required to prepare 0.1 M H_{3}PO_{4} from 100 ml of 0.5 M solution.

Explanation:

Given: M_{1} = 0.1 M,    V_{1} = ?

M_{2} = 0.5 M,       V_{2} = 100 mL

Formula used to calculate the volume of water is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\0.1 M \times V_{1} = 0.5 M \times 100 mL\\V_{1} = 500 mL

Thus, we can conclude that a volume of 500 mL water is required to prepare 0.1 M H_{3}PO_{4} from 100 ml of 0.5 M solution.
