Why is the chemical equation 2H2 O2 balanced?
2H2 + O2 ---->2H2O is balanced for the following reasons. Hydrogen and oxygen exist as H2 and O2 and not H and O. The product is water with a formula of H2O. To get balance the number of atoms of reactants and the number of atoms of products must be equal. They are in the balanced equation above. For these reasons the equation is balanced.
What is the balanced symbol equation of water?
O + h2 = h2o
What is the balanced equation for lithium and oxygen?
2Li + O --> Li2O
A chemical equation that shows the same number of each kind of atoms on both sides of the equation is what?
Remember the Law of Conservation of Mass. This means that the given number of atoms and elements on both sides of the reaction eq'n MUST be the same. It is also known as a BALANCED EQUATION. e.g. 2KOH + H2SO4 = K2SO4 + 2H2O In this case the prefix '2' of KOH, indicates that there are 2 x K , 2 x O & 2 x H. The suffix '2' in H2SO4 indicates 2 X H , only 1 x S & 4 x O. So overall on the reaction side we have 2 x K 6 x O 4 X H 1 x S . You MUST end up with this same numbers on the product side. Hence we have in K2SO4 , 2 x K, 1 x S , & 4 x O. The prefix '2' of H2O indicates that there are 2 x 2 = 4 H & 2 x 1 =2 O Hence, overall we have on the product side 2 x K 4 + 2 = 6 x O 4 x H 1 x S This agrees with the reactant numbers and elements, so the chemical reaction equation is balanced. Hope that helps!!!!
Is H2O2--H2O plus O2 a balanced equation?
No. There are two O's on the right side and three on the left. The balanced form is 2 H202 -> 2 H20 + 02. All of the O's are the letter 0 in this equation. All numbers are subscripts except the two 2's in front of the H's that have a space after them. I've taken college-level chemistry, so I remember how to do this.

What is balanced equation for C2H6 plus O2 equals H2O plus CO?
The anwer is 2 (C2H6) + 7(O2) =4 (CO2) + 6 ( H2O) left side : C=4 , H= 12, O=14 right side : C=4 , H= 12, O=14 so they are balanced.
