How many water molecules are produced when 5.2 g O2are reacted? 5.2 g O2* 1 mol O2* 2 mol H2O* 6.02 *1023molecules H2O= 1.96 * 1023molecules H2O32 g O21 mol O21 mol H2O 32.

Here, we have to calculate the number of molecules in each sample. Therefore, 3.5 g of of H2O contains 1.169 x 1023 molecules of H2O.

['2H2 + O2 -> 2H2O. This means that for every 2 molecules of Hydrogen gas, one molecule of Oxygen is needed to make 2 molecules of water. ... ', 'Enthalpy of reaction = (Enthalpy of products) - (Enthalpy of reactants) ... ', 'Enthalpy= -285.83-(0+0)', 'This means Enthalpy of formation of water=-285.83kJ/mol.']

The process uses oxygen and glucose and results in carbon dioxide (CO2), water (H2O), and usable energy. Oxygen and glucose are the reactants.

Answer and Explanation: 0.133 mole of oxygen gas is required to react to form 0.100 mole of water.

How much of this, plus how much of that gives how much of something else? The balanced chemical equation tells us that two molecules of water in the liquid state react to form two molecules of H2 in the gas state and one molecule of O2 in the gas state.

For 1 mole of H2O2, it will yield to 0.5 moles of O2. Adding those up, 5 moles of H2O2 will yield to 2.5 moles of O2.

The second conversion factor reflects the number of atoms contained within each molecule. Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms.

The number of molecules in 16 gm of oxygen are 0.5 (= 16/32 moles). Thus the number of molecules in 16 gm or 0.5 mole of oxygen gas are 0.5 x 6.023 x 10^(23) = 3.012 x 10^(23) molecules.

Equation 2 shows that two molecules of hydrogen react with one molecule of oxygen to produce two molecules of water. The two molecules of hydrogen each contain two hydrogen atoms and so do the two molecules of water. Therefore, there are now four hydrogen atoms in both reactants and products.

Since we have 4 moles of oxygen, we can put that directly into the equation. Assuming that oxygen is our limiting reactant (because it is not otherwise specified), we can find that per one mole of oxygen, we get two moles of water. This means that per four moles of oxygen, we get eight moles of water.

How many molecules of H2O are present in 0.500 mol of water? 1 mol of water contains 6.022 × 1023 H2O molecules Therefore 0.500 mol contains 0.500 × (6.022 × 1023) = 3.01 × 1023 H2O molecules.

A single mole of O2 has 6.02 * 10^23 oxygen molecules. Each oxygen has 2 atoms of oxygen. Therefore, 2(6.02 * 10^23) = 1.2 * 10^24.

6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation. For each molecule of glucose produced: 6 water water molecules are oxidized, and become the source of electrons for carbon dioxide reduction.

If we want to make 5 molecules of water, we need 10 hydrogen atoms and 5 oxygen atoms. The ratio of atoms we will need to make any number of water molecules is the same: 2 hydrogen atoms to 1 oxygen atom.

There are 6 of these molecules. H2O is a molecule made of H for hydrogen and O for oxygen. There are 12 of these molecules. The smaller number is the number of atoms of the element to the left of it.
