Answer 1

Answer:

Question: The equation for water is H2 +O2 → H2O. To balance the equation, which coefficient should be placed in front of H2 and H2O?

Answer: B.)2

Explanation:

The coefficient that would need to be placed in front of the H2, to balance the equation would be 2. After doing this all of the atoms for their respective elements will be balanced.

Answer 2

To balance the equation, coefficient 2 should be placed in front of H2 and H2O.

BALANCING EQUATION:

• A chemical equation is said to be balanced if the number of atoms of each element on both sides of the equation are the same.

• According to this question, an equation that combines hydrogen and oxygen gases to form water was given as follows:

• H2 + O2 → H2O

• To balance the above equation, we make use of coefficient 2 to ensure that the number of atoms (4) of hydrogen are the same on both sides. The balanced equation is as follows:

• 2H2 + O2 → 2H2O
