How many grams of Mg must react with HCl in order to produce 80 mL of hydrogen gas at STP?
The key is to understand that Mg is limiting. Therefore, the final number of moles of H2 will equal the starting number of moles of Mg. Using gas law equations we can first find the moles of H2 and then find the moles of Mg. 1. PV = nRT --> n = PV/RT P = 760 mm Hg (pressure at STP) V = 80.0 mL (given) R = 62,400 mL-mm Hg/mol-K (constant) T = 273 K (temp. at STP) Now you have all the information you need to solve for the number of moles of Mg. Solve for moles and convert to grams.

Which metals react with acid to produce hydrogen?
I only know 3 metals that react with acids to produce hydrogen. They are Zinc, iron and magnesium. There are 3 acids which react with them: and It will produce hydrogen gas which is the lightest known gas and is flammable :)
If 4.0 g of hydrogen react with chlorine to produce 146 g of hydrogen chloride how many grams of chlorine reacted?
The balanced chemical equation for the reaction between hydrogen and chlorine is: H2 + Cl2 -> 2HCl. From the equation, we see that 1 molecule of Cl2 reacts with 1 molecule of H2 to produce 2 molecules of HCl. Thus, 4.0 g of hydrogen would react with 118.5 g of chlorine (146 g of hydrogen chloride - 27.5 g of hydrogen).
Nitrogen from the air can react with what element to make ammonia for fertilizer?
Hydrogen. Nitrogen from the air can react with hydrogen to produce ammonia for fertilizer in the Haber-Bosch process.
If you start with seventy grams of nitrogen and twenty grams of hydrogen how many grams of ammonia will be formed and how many grams of hydrogen are leftover?
To form ammonia (NH3) from nitrogen (N2) and hydrogen (H2), the balanced chemical equation is N2 + 3H2 → 2NH3. This means that for every mole of nitrogen, 3 moles of hydrogen are required. Given that nitrogen is limiting in this case, all 70 grams of nitrogen will react with 210 grams (3 times 70) of hydrogen to form 70 grams of ammonia. This reaction will consume all the hydrogen, leaving no grams of hydrogen leftover.
What is the total mass of water formed when 8 grams of hydrogen reacts completely with 64 grams of ovygen?
The balanced chemical equation for the reaction of hydrogen and oxygen to form water is 2H2 + O2 -> 2H2O. Based on the equation, for every 2 grams of hydrogen, 64 grams of oxygen are needed to form 36 grams of water. Thus, if 8 grams of hydrogen react completely with 64 grams of oxygen, the total mass of water formed would be 36 grams.
How many grams of water are produced when 2.5 mil oxygen reacts with hydrogen?
When 2.5 moles of oxygen react with hydrogen, they react in a 1:2 ratio to produce water. Therefore, 2.5 moles of oxygen will produce 5 moles of water. To convert moles to grams, you'll need to know the molar mass of water, which is approximately 18 grams/mol. So, 2.5 moles of oxygen will produce 90 grams (5 moles x 18 grams/mole) of water.
What do metals react with acids to produce?
Metals react with acids to produce a salt and hydrogen gas.
When acids react with active metals they always produce what?
When acids react with active metals, they always produce a salt and hydrogen gas.

What metals react most vigorously in order?
Potassium, sodium, and lithium are the three most reactive metals in order. They react vigorously with water to produce hydrogen gas and hydroxide ions.
Do acids make hydrogen when they react with some metals?
Yes, acids can react with certain metals to produce hydrogen gas. The acid will donate protons to the metal, causing it to lose electrons and form metal ions. The liberated electrons then reduce hydrogen ions in the acid to produce hydrogen gas.
Does copper react with water to produce hydrogen?
yes it does.
Is carbon dioxide react with acid to produce hydrogen gas?
No.
What substance can acids react to produce hydrogen gas?
Acids can react with metals (such as zinc or magnesium) to produce hydrogen gas. The acid reacts with the metal to form a salt and hydrogen gas is released as a byproduct of the reaction.
Do acids and metals react to make oxygen?
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.

Thus, 4.0 g of hydrogen would react with 118.5 g of chlorine (146 g of hydrogen chloride - 27.5 g of hydrogen).
What happens when metals react with bases?
When metals react with bases, they often produce hydrogen gas and a salt. The metal displaces hydrogen from the base to form the salt, while hydrogen gas is released as a byproduct. This type of reaction is known as a displacement reaction.
