H2 plus O2 equals H2O If you have 1.42 moles of hydrogen how many moles of oxygen will react with it?
Balanced equation first. 2H2 + O2 >> 2H2O 1.42 mol H2 ( 1mol O2/2mol H2 ) = 0.71mol O2 to react with H2
What is the balanced equation for the reaction between 02 and H2?
2h2 + o2 -> 2h2o All letters capitalized!!
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.
What does oxygen plus hydrogen?
The product is water:2 H2 + O2 = 2 H2O
In the reaction 2H2o-----2H2 o2 What are the products?
Products are at the right side --> hydrogen H2 and oxygen O2
What is h20 h2 o2 balanced?
2h2o -> 2h2 + o2

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.)
What is the coefficient for H20 when the following equation is balanced K plus H20 plus KOH plus H2?
2K + 2H2O --> 2KOH + H2 The balanced equation shows that there is a 2 in front of water.
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.
How do you balance 2H2 O2 2H2O O2?
2H2O2 ==> 2H2O + O2 the equation is balanced
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)
Is H2O-H2 plus O2 a balanced chemical equation?
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
What is the Balanced equation for the combustion reaction of pure oxygen and pure hydrogen to produce water?
O2(g)+2H2(g) -> 2H2O(g) (Remmeber heat/energy must also go into the reaction.) 2H2 + O2 ---> 2H2O
What is the balanced equation for methane burns oxygen to form water and carbon diooxide?
Unbalanced CH4 + O2 = H2O + CO2 Balanced CH4 + 2O2 = 2H20 + CO2
