The equation ( \text{H}_2 + \text{O}_2 \rightarrow 2\text{H}_2\text{O} ) is balanced. On the left side, there are 2 hydrogen atoms and 2 oxygen atoms, while on the right side, there are 4 hydrogen atoms and 2 oxygen atoms. Therefore, the equation is unbalanced as the number of hydrogen atoms is not equal on both sides. To balance it, the correct equation should be ( 2\text{H}_2 + \text{O}_2 \rightarrow 2\text{H}_2\text{O} ).

H2 plus O2 equals H2O If you have 1.42 moles of hydrogen how many moles of oxygen will react with it?
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.

Is methane balanced or unbalanced?
Methane is a molecule with the formula of CH4 .!!! It is only unbalanced if it is involved in a chemical reaction (combustion). e.g. CH4 + O2 = 2H2O + C Here it is unbalanced(too much CH4) because CO2( Carbon Dioxide ) is the other product, which is NOT produced in this reaction. The equation CH4 + 2O2 = 2H2O + CO2 Methane is now balanced, just the correct quantity for the reaction to complete. NB For all compounds, they are neither balanced nor unbalanced. It is the quantities that are reacted that make the reaction (un)/balanced.

If a sample of pure hydrogen gas is ignited very carefully the hydrogen burns gently combining with the oxygen gas of the air to form water vapor write the unbalanced chemical equation for this react?
H2(g) + O2(g) --> H2O(l) unbalanced. 2H2(g) + O2(g) ==> 2H2O(l) balanced.
What is h20 h2 o2 balanced?
The chemical equation given “H2 + O2 -> H2O” is not balanced. To balance it, you need to modify the coefficients in front of the molecules. The balanced equation should be: "2H2 + O2 -> 2H2O" where you have two molecules of hydrogen gas reacting with one molecule of oxygen gas to produce two molecules of water.
What is the balanced symbol equation of water?
The balanced symbol equation for water is 2H2 + O2 -> 2H2O.
Balance the equation1.H2+ O2=H2O?
= H2+O2 =2H2+O2=2H2O
Is this chemical equation balanced or unbalanced H2 plus O2 equals H2O?
NO, it is unbalanced because you're putting in2 Oxygen (O) atoms and only getting one out in the product. What you are doing is burning pure Hydrogen (H) gas in air and, it's reacting with the Oxygen in the air to form Water. The balanced equation is: 2(H2) + O2—> 2H2O (+ you're going to get some Thermal Energy/ Heat generated.)

Is the formula 2h2 plus o2 balanced or unbalanced?
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.
Which set of coefficients balance the following chemical equation H2 02 H20?
The balanced chemical equation is 2H2 + O2 → 2H2O. This means that the coefficients are 2, 1, and 2, respectively.
Is 2H2 O2---2H20 balanced?
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

How do you easily balance a chemical equation PLEASE Help I am having so much trouble and have 41 questions for homework due tomorrow?
Do not change any formulas. The only thing you can change is the coefficient in front of a formula. If no number is written, the coefficient is understood to be one. The number of atoms of each element is the coefficient times the subscript. No subscript is understood to be one. For example, 6CO2 has a coefficient of 6, and it means that there are 6 atoms of C, and 12 atoms of O. 3H2O means that there are 6 atoms of H and 3 atoms of O. The number of atoms of each element has to be the same on both sides. This makes the equation balanced and conforms to the law of conservation of matter. You add coefficients in order to balance an equation. For example, H2 + O2 --> H2O is unbalanced. The number of oxygen atoms is not the same on both sides. So, add a 2 in front of H2O to get 2 oxygen atoms on both sides. H2 + O2 --> 2H2O. That balances the H2O, but now the H is not balanced. So, add a 2 in front of the H2 in order to get 4 H on both sides. 2H2 + O2 --> 2H2O. The equation is now balanced because there are the same number of atoms of each element on both sides of the equation. To review the steps: H2 + O2 --> H2O (unbalanced) H2 + O2 --> 2H2O (still unbalanced) 2H2 + O2 --> 2H2O (balanced)
