How many grams of O2 are required to completely react with 2g of H2?
The balanced chemical equation for the reaction of H2 with O2 to form H2O is: 2H2 + O2 -> 2H2O From the equation, it can be seen that 1 mole of O2 reacts with 2 moles of H2. Since the molar mass of H2 is 2 g/mol and the mass given is 2g, there is 1 mole of H2. Therefore, 1 mole of O2 is needed, which is 32g.
What is the minimum number of moles of O2 required to produce one mole of CO2?
One mole of CO2 requires one mole of O2 to produce during combustion of carbon-containing compounds.
How many particles are there in a mole of O2?
6.02214076×1023
If 0.440 mole of HgO reacts how many moles of O2 will be produced?
1 mole of HgO produces 1 mole of O2 according to the balanced chemical equation for the reaction. Therefore, 0.440 moles of HgO will produce 0.440 moles of O2.
What is mass of one mole of oxygen molecule?
The molar mass of oxygen is approximately 16 grams per mole. This means that one mole of oxygen molecules (O2) would have a mass of 32 grams, since each molecule of O2 consists of 2 oxygen atoms.
What is the difference between the mass of a mole of oxygen and a mole of O2 molecules?
A mole of oxygen atoms has a mass of approximately 16 grams. A mole of O2 has a mass of approximately 32 grams. A mole is 6.02 x 1023 particles and as such a mole of oxygen atoms has only half the mass of a mole of oxygen molecules.
What is the total number of moles of NO produced when 1.0 mole of O2 is completely consumed?
When 1.0 mole of O2 is completely consumed in the reaction to form NO, 1.0 mole of NO is produced since the balanced equation for the reaction is 2 O2 + 2 N2 -> 2 NO. This means that the mole ratio between O2 and NO is 1:1.
How many moles of H2O are product from reaction of 355 g of O2?
To find the moles of H2O produced, first calculate the moles of O2 present in 355 g using its molar mass. Then, use the mole ratio from the balanced chemical equation of the reaction to determine the moles of H2O produced.
How many atoms of oxygen are there in 82.5g of molecular oxygen?
82.5 grams O2 (1 mole O2/32 grams)(6.022 X 10^23/1 mole O2) = 1.55 X 10^24 atoms of O2
Is Sr O2 --- 2SrO balanced?
Yes, the equation is balanced. Two moles of Sr react with one mole of O2 to produce two moles of SrO.
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 ------------------------------------------
How many moles of P2 O5 are produced from 8.00 mole of O2?
The balanced equation for the reaction must be given to determine the molar ratio between O2 and P2O5. Without that information, it is not possible to determine the exact number of moles of P2O5 produced from 8.00 moles of O2.
