Answer:

<h2>13.64 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

From the question we have

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{25 \times 30}{55}  =  \frac{750}{55}  \\  = 13.636363...

We have the final answer as

<h3>13.64 L</h3>

Hope this helps you

The product side of a chemical reaction is shown.
Inga [223]

The number that represents the coefficient on the product side of the chemical reaction, -- > 7Ti_2(SO_4)_3 is 7.

<h3>Coefficients of chemical equations</h3>

In equations representing chemical reactions, the coefficient of each reactant or product of a reaction is the number that comes on the left-hand side just before the chemical formula.

The coefficient of each species in a chemical reaction is obtainable when the equation of the reaction is balanced.

For example, in the following equation: 2A + B = 3C + D

The coefficients of A, B, C, and D are 2, 1, 3, and 1 respectively.

Applying this to the product side of a chemical reaction;  -- > 7Ti_2(SO_4)_3

It means that the coefficient of the product is 7.

Allisa [31]
<h3>Answer:</h3>
  • They show the elements of make up a compound
  • They show the types of atoms that make up a molecule
  • They show the number of each type of atom in a molecule
<h3>Explanation:</h3>

To answer this question we need to know what is a compound.

  • A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
  • A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
  • Additionally, the chemical formula shows the number of each type of atom in a molecule.
  • In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.
