No, this would make 5 moles. This is because water is H2O. This means that for each oxygen molecule used, there will be 2 hydrogen molecules used. In the given equation Only 5 moles of oxygen could be used to pair with all 10 moles of hydrogen, therefore giving you an excess of 5 oxygen molecules.
3 moles of O, so that must be 6 moles of O2
We need 8 moles potassium chloride.
Hydrochloric acid is a mixture water: acid with different concentrations.For hydrogen chloride (HCl) you need 0,475 moles.
By dissolving 2 moles of the compound in 1 L of water
By dissolving 2 moles of the compound in 1 L of water
Write out the equation first: 10H2 + 10O2 --> xH2O Since there are 2 moles of Hydrogen for every mole of Oxygen and equal moles of both are given, the Hydrogen limits the reaction as the limiting reactant. 10 moles of Hydrogen can make 10 moles of H2O with 5 moles of Oxygen left over. Think of it logically: H2 is two hydrogen atoms and water needs two hydrogen atoms, so it is a one-to-one reaction.
3.2 moles of water (H2O)
3 moles of O, so that must be 6 moles of O2
8 moles
for each mole of anything there is 6.022x10^23 molecules. Therefore for 5 moles of water there is 5 x 6.022x10^23 = 3.011x10^24 molecules of water
8 moles of KCl are needed.
We need 8 moles potassium chloride.
4 moles of oxygen atoms are present in 4 moles of H2O
The synthesis reaction is 2 H2 + O2 = 2 H2O. Every two moles of hydrogen reacts with one mole of oxygen to make two moles of water. Then 30.0 grams of water is 1.67 moles, and 1.67 moles of H2 has a mass of 3.37 grams. 25.0 grams of O2 is .781 moles, so 1.562 moles of H2 are needed, or 3.15 grams.
Hydrochloric acid is a mixture water: acid with different concentrations.For hydrogen chloride (HCl) you need 0,475 moles.
Na +H2O -> NaOH +(1/2)H2 Every mole of Sodium requires one mole of water to make one mole of Sodium Hydroxide. So two moles of Sodium will produce two moles of Sodium Hydroxide. If there are three moles of water in the initial reaction then there will be one mole of water left over after reacting with two moles of Sodium. This reaction will produce half a mole of hydrogen gas.
Moles don't really make sound but they might make kinda a little sound.
