Zn + 2HCl >> ZnCl2 + H2
13.05 grams Zn (1mol Zn/65.41g Zn)(1mol H2/1mol Zn)(6.022 X 1023/1mol H2)
= 1.201 X 1023 molecules of H2 produced.

How many molecules are produced when 2.5g of zinc react with an excess of hydrochloric acid?
molecules of what?
How many water molecules (H2O) can be produced from 6 molecules of hydrogen gas (purple) reacting with 6 molecules of oxygen gas (turquoise)?
6H2 + 6O2 ---> 6H2O + 3O2 This reaction leave excess unreacted oxygen behind.
What is the mass of hydrogen gas released from 2.70 g of aluminum metal and hydrochloric acid in grams?
I assume you mean excess hydrochloric acid. Balanced equation. 2Al + 6HCl = 2AlCl3 + 3H2 2.70 grams Al (1 mole Al/26.98 grams)(3 mole H2/2 mole Al)(2.016 grams/1 mole H2) = 0.303 grams hydrogen gas produced --------------------------------------------------
When 1.187 grams of metallic oxide is reduced with excess hydrogen 1.054 grams of the metal is produced What is the metallic oxide?
This oxide may be CdO.
What is the color of the indicator when an excess of hydrochloric acid has been added?
Red
How many molecules are produced when 2.5g of zinc react with an excess of hydrochloric acid?
molecules of what?
What positive ions is produced in excess when acids are dissolved in water?
Hydronium(H3O+) ions, which are formed when Hydrogen(H+) ions combine with water molecules.
When acids in water what positive ion is produced in excess?
When acids in water hydrogen positive ion is produced in excess. It is this hydrogen positive ion that gives acidity of a solution.
How many water molecules (H2O) can be produced from 6 molecules of hydrogen gas (purple) reacting with 6 molecules of oxygen gas (turquoise)?
6H2 + 6O2 ---> 6H2O + 3O2 This reaction leave excess unreacted oxygen behind.
What molecules are produced from excess fat breakdown?
Mostly free fatty acids and triglycerides.
How many mol of water will be produced from combining 4.85 mol of oxygen with excess hydrogen?
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
What volume of hydrogen measured at 0.95 ATM and 27c can be prepared by the reaction of 0.500 mole zinc with an excess of hydrochloric acid?
12.9 L
What is the mass of hydrogen gas released from 2.70 g of aluminum metal and hydrochloric acid in grams?
I assume you mean excess hydrochloric acid. Balanced equation. 2Al + 6HCl = 2AlCl3 + 3H2 2.70 grams Al (1 mole Al/26.98 grams)(3 mole H2/2 mole Al)(2.016 grams/1 mole H2) = 0.303 grams hydrogen gas produced --------------------------------------------------
How many moles of tungsten can be produced from 2405moles of hydrogen and excess WO3?
The reaction is:WO3 + 3 H2 = W + 3 H2OThree moles of hydrogen for one mole of wolfram.
List the ways the body handles the excess hydrogen ions always being produced?
HCO3(-) Bicarbonate ion. That is one buffer.
When 1.187 grams of metallic oxide is reduced with excess hydrogen 1.054 grams of the metal is produced What is the metallic oxide?
This oxide may be CdO.
Is acid matter?
Acidity is produced by an excess of hydrogen ions (actually to be completely correct an excess of pi-hydronium ions) in a water solution. So, yes.
