hydrogen peroxide
The reactants in this equation are hydrogen gas (H2) and oxygen gas (O2).
This simple equation is: 2H2 + O2 = 2H2O
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
The balanced chemical equation is 2HBr + H2 + Br2 + N2O → N2 + O2 + HBr + H2 + Br2. The equation provided in your question doesn't appear to balance correctly, so I attempted to balance it based on the chemical species presented. It's essential to ensure that the number of atoms of each element is the same on both sides of the equation.
H is the atomic symbol for hydrogen, the 2 subscript means it is diatomic.
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
In order to have a balanced equation, adding the reactant H2 And O2 (H2+O2) have to come out equal on the product side and the reactant side. This would look like H2+O2 = H2O2
2h2 + o2 -> 2h2o All letters capitalized!!
The product is water:2 H2 + O2 = 2 H2O
First off, you decide the product (becomes easier after a while of doing chemistry). The product is H2O (water). O2+H2=>H2O, but this is not stochiometrically balanced, so you have to change the amount of H2O's on the right side of equation and then to balance the amount of hydrogens. If you add a 2 in front of both, you get O2 + 2H2 => 2H2O
The balanced chemical equation shows that 1 mole of oxygen reacts with 2 moles of hydrogen to form water. Therefore, if you have 1.42 moles of hydrogen, you would need 0.71 moles of oxygen to react with it in this reaction.
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
