Respuesta :

The whole Balanced Reactions Quick Check for Honors Chemistry A is

1) A. The reactants and products have the same number and type of atoms, but the atoms may be recombined.

2) B. It shows how many molecules there are of a particular substance.

3) D. NaOH + HCl → NaCl + H2O

4) A. Atoms always remain intact during chemical reactions.

5) D. 4, 4

The balanced chemical equation is:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

The numbers that balanced the equation are: 4, 4

To know the number that balanced the equation, we shall simply balance the equation.

CH₄ + Cl₂ —> CCl₄ + HCl

There are 4 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 4 before HCl as shown below:

CH₄ + Cl₂ —> CCl₄ + 4HCl

There are 2 atoms of Cl on the left side and a total of 8 atoms on the right side. It can be balance by writing 4 before Cl₂ as shown below:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

Now, the equation is balanced

The numbers that balanced the equation are 4,4
