2H2 + O2 ---> 2H20 is balanced when total numbers of atoms of EACH element seperately are equal on both sides ('Reactant' and 'Product' side):
Left (2x H2=) 4 H atoms and (1x2 O=) 2 O atoms
Right (2x H2=) 4 H's and (2x1 O=) 2 O's
The balanced equation is: 4H₂ + 4NO → 4H₂O + 2N₂.
The balanced chemical equation for the reaction is: 2H2(g) + O2(g) → 2H2O(g). This equation indicates that when 2 moles of hydrogen gas react with 1 mole of oxygen gas, they produce 2 moles of water vapor.
Water (H2O) is made of 2 molecules of hydrogen and one oxygen. When you separate water into a gaseous state by electrolysing the water, you have separated the oxygen and hydrogen molecules. If you were to bubble that gas (Brown's gas) through water, the water absorbs the extra 2 molecules of hydrogen and one molecule of oxygen. 2H2O + 2H2 + O2 = 2[H3O]+ + 2[OH]-
The balanced equation for this reaction is: 4 H2 + 4 NO -> 4 H2O + 2 N2.
One molecule of Oxygen Gas (O2) combines with two molecules of Hydrogen Gas (2H2) to form two molecules of water 2H2O. O2+2H2=> 2H2O There are the same numbers of H's and O's either side of the = meaning the equation is balanced, in respect of the fact that Oxygen and Hydrogen Gas have diatomic molecules (2 atoms stick together)
The balanced equation for the reaction of C + 2H2 → CH4 is: C + 2H2 → CH4. This equation is already balanced. Each side has 1 carbon atom and 4 hydrogen atoms.
Co + 2h2 -> ch3oh All letters capitals!
C+ 2H2--> CH4 is the balanced equation.
2h2 + o2 -> 2h2o All letters capitalized!!
The balanced chemical equation for the reaction C2H2 + H2 → C2H6 is: C2H2 + 2H2 → C2H6
2H2O2 ==> 2H2O + O2 the equation is balanced
The balanced chemical equation for the synthesis of methanol from carbon monoxide and hydrogen gas is: CO + 2H2 -> CH3OH
The balanced symbol equation for water is 2H2 + O2 -> 2H2O.
The formula 2H2 + O2 is unbalanced. It represents the reaction of hydrogen gas with oxygen gas to form water (H2O). To balance the equation, it should be written as 2H2 + O2 → 2H2O.
2h2 + o2 2h2o
2H2 + O2 --> 2H2O
This is not an equation at all. An example of a correct (and balanced) equation would be: 2H2 + O2 --> 2 H2O
