Question

h2+o2 ---------->h2o balance the equation with the steps​

Answer 1

Answer:

Balancing equation = 2h2 + O2 = 2h20

Answer 2

Heya dear

Your answer ❤❤❤

Hydrogen and oxygen react to form water but you just cannot write the equation as 2H + 1O because hydrogen and oxygen do not exist as single atoms but rather as the molecules H2 and O2. The equation should show these molecules as the reactants on the left side of the reaction arrow.

H2 + O2 � H2O

In this reaction there are 2 hydrogen atoms on the left side of the reaction arrow and 2 hydrogen atoms on the right side of the reaction arrow so the reaction is balanced with respect to the hydrogen. However there are 2 oxygen atoms on the left and only one on the right. To correct this imbalance, place a 2 in front of the H2O. Now the oxygen atoms are balanced with 2 on the left and two on the right. The hydrogen atoms are no longer balanced because there are 4 hydrogen atoms on the right and only 2 on the left.

H2 + O2 � 2 H2O

The equation will finally be balanced when the one molecule of H2 on the left is changed to 2 molecules.

2 H2 + O2 � 2 H2O

This equation is now a balanced equation. It tells us that 2 molecules of hydrogen react with 1 molecule of oxygen to form 2 molecules of water.
