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
In the equation 2 H2 plus O2 --- 2 H2O what substances are the reactants?
H2 and O2.
How do you balance the chemical equation O2 plus H2?
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
How many moles of H2O are product from reaction of 355 g of O2?
Balanced equation. 2H2 + O2 -> 2H2O 355 grams O2/32 grams = 11.1 moles O2 check for limiting reactant 11.1 moles O2 (2 mole H2/1 mole O2) = 22.2 mole H2 and H2 has no where near that many moles, so limits and drives reaction so, as they are one to one...... 22.2 moles of H2O are produced
How many moles O2 must react with excess H2 to form 7.89 mol H2O?
Oxygen limits the reaction, so......Balanced equation. 2H2 + O2 -> 2H2O 7.89 mole H2O (1 mole O2/2 mole H2O) = 3.95 mole oxygen gas needed ------------------------------------------
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 mistake in H2 plus O2 equals H20?
It is not balanced. There should be a 2 in front of H2 and H2O
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
Write a balanced equation for the ignition reaction of hydrogen in air?
2 H2 + O2 = 2 H2O
Balance the equation1.H2+ O2=H2O?
= H2+O2 =2H2+O2=2H2O
What is the percent yield of h2o if 58g h2o are produced by combining 60g o2 and 7g h2?
Balanced equation. 2H2 + O2 >> 2H2O ( now find limiting reactant ) 7 grams H2 (1 mole H2/2.016 grams) = 3.472 moles H2 60 grams O2 (1 mole O2/32 grams) = 1.875 moles O2 1.875 moles O2 (2 mole H2/1 mole O2) = 3.75 mole H2 ( checked O2, but I know H2 limits because you do not have 3.75 moles H2, so H2 drives reaction) 3.472 moles H2 (2 mole H2O/2 mole H2)(18.016 grams/1 mole H2O) = 62.552 grams H2O produced, so; 58 grams/62.552 times 100 = 92.7% yield of H2O, call it 93%
Why is this chemical equation not balanced H2 O2 H2O?
Because there are 2 oxygen atoms on the reactants side and only one on the products side. You can either add a coefficient of 1/2 on the O2 or you can add a coefficient of 2 on H2 and H2O.
Balanced reaction for the decomposition of water?
Water decomposes into Oxygen and Hydrogen gases, each of which is a 2 atom molecule: H20 -> H2 + O2 BUT that's not balanced - there's Oxygen 'appearing' from nowhere on the right side so to balance it (2) H2O -> H2 + O2 But now we have 4 Hydrogens on left and only two on right (2) H2O -> (2)H2 + O2 4 hydrogens and 2 oxygen - > 4 hydrogens and 2 Oxygens Balanced!
In the equation 2 H2 plus O2 --- 2 H2O what substances are the reactants?
H2 and O2.
Why does h2 explode?
H2 (Hydrogen) reacts with O2 (Oxygen) to form water. 2 H2 + O2 --> 2 H2O
How do you balance this equation SnO2 plus H2 --- Sn plus H2O?
Balanced equation: 2 H2 + O2 --> 2 H2O
What is h20 h2 o2 balanced?
2h2o -> 2h2 + o2
