Balance the following ec luation: underline ( )H_(2)+underline ( )O_(2)arrow underline ( )H_(2)O 1,1,3 2,2,2 2,1,2

To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.Given equation: Step 1: Count the number of atoms of each element on both sides of the equation.On the left side:- Hydrogen (H): 2 atoms- Oxygen (O): 2 atomsOn the right side:- Hydrogen (H): 2 atoms- Oxygen (O): 1 atomStep 2: Balance the oxygen atoms by placing a coefficient of 2 in front of on the right side. Step 3: Count the number of atoms of each element again.On the left side:- Hydrogen (H): 2 atoms- Oxygen (O): 2 atomsOn the right side:- Hydrogen (H): 4 atoms- Oxygen (O): 2 atomsStep 4: Balance the hydrogen atoms by placing a coefficient of 2 in front of on the left side. Step 5: Verify that the number of atoms of each element is the same on both sides of the equation.On the left side:- Hydrogen (H): 4 atoms- Oxygen (O): 2 atomsOn the right side:- Hydrogen (H): 4 atoms- Oxygen (O): 2 atomsThe balanced equation is: Therefore, the correct answer is:
