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 grams of calcium are required to react with 7.75 grams of water to produce calcium hydroxide and hydrogen gas?
8.62
What has more atoms 17.031 grams of ammonia or 72.922 grams of hydrogen chloride?
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
How many grams of hydrogen is produced when 167.12 g of hydrochloric acid is reacted with copper?
Cu + 2 HCl --> CuCl2 + H2 167.12 g HCl * (1 mol HCl/36.46 g HCl) * (1 mol H2/2 mol HCl) * (2.02 g/1 mol H2) = 4.629 g H2 4.63 grams of hydrogen gas is produced when 167.12 grams of hydrochloric acid reacts with copper.
What is the total volume of hydrogen gas produced with 5.00 grams of zinc react with HCl?
The reaction is:Zn + HCl = ZnCl2 + H2The volume of hydrogen ia 1,7 L.
What is the volume of a sample with 96.2 grams?
It depends entirely on what substance you're working with. For example, the volume of 96.2 grams of hydrogen is a lot more than the volume of 96.2 grams of lead.
What is atomic no of hydrochloric acid?
hydrochloric acid does not have an atomic number. Only elements have atomic numbers and hydrochloric acid is a compound composed of two non-metal elements: hydrogen and chlorine, as you might have guessed by the name. However: Hydrogen's atomic number is 1 and Chlorine's atomic number is 17
How many grams of hydrogen must be added to 800 grams of oxygen to produce 900 grams of water?
i think that you have to add 100 gramd to produce the amount of 900 grams

What is the volume of a mass of 68 grams?
The answer to that depends on the density of the substance in question.For instance the volume of 68 grams of Lead would be smaller than the volume of an equivalent mass of gaseous hydrogen.

How many moles of hydrogen gas H2 is produced if 20.0 mol of Zn are added to hydrochloric acid HCl according to the equation Zn plus 2HCl --- ZnCl2 plus H2?
20,1588 grams of hydrogen
What is amount of hydrogen in one liter of petrol?
Petrol contains about 84% carbon and 16% hydrogen by weight so a litre weighing 700 grams contains 588 grams of carbon and 112 grams of hydrogen. In the engine it would burn with 2464 grams of oxygen to produce 2156 grams of CO2 and 1008 grams of water (steam), which is normally invisible but can be seen in the exhaust gases from a cold engine.
