HCl —> H+ + Cl-
One of the products of dissociation is H+, making the solution Acidic.

Which set of coefficients will balance this chemical equation?

Montano1993 [528]

Answer:

Option B is correct = 1,3

Explanation:

Chemical equation:

C₂H₄ + O₂ → CO₂ + H₂O

Balanced chemical equation:

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

Step 1:

Left side Right side

C = 2 C = 1

H = 4 O = 3

O = 2 H = 2

Step 2:

C₂H₄ + O₂ → 2CO₂ + H₂O

Left side Right side

C = 2 C = 2

H = 4 O = 5

O = 2 H = 2

Step 3:

C₂H₄ + O₂ → 2CO₂ + 2H₂O

Left side Right side

C = 2 C = 2

H = 4 O = 6

O = 2 H = 4

Step 4:

C₂H₄ + 3O₂ → 2CO₂ + 2H₂O

Left side Right side

C = 2 C = 2

H = 4 O = 6

O = 6 H = 4

When the temperature increases, the molecules of the gas gain energy. Therefore, they move faster.

This causes the molecules to hit the walls of the container more frequently and with greater force. Hence the pressure inside the container increases.
