What mass of hydrogen is produced when 24g of magnesium react with an excess of sulfuric acid?
Balanced equation.
Mg + H2SO4 -> MgSO4 + H2
------------------------------------- ( sufuric acid in excess---magnesium limits, drives reaction )
24 grams magnesium (1 mole Mg/24.31 g)(1 mole H2/1 mole Mg)(2.016 g/1 mole H2)
= 1.9 grams of hydrogen gas produced ( can call it 2.0 grams )

What else can I help you with?
An excess of Mg is reacted with 1 mole of HCl dissolved in water- determine the mass of hydrogen produced?
The reaction between magnesium and hydrochloric acid produces hydrogen gas according to the equation: Mg + 2HCl -> MgCl2 + H2. For every 1 mole of magnesium reacted, 1 mole of hydrogen gas is produced. Using the molar mass of hydrogen (1 g/mol), the mass of hydrogen produced would be 1 gram when 1 mole of magnesium is reacted.
How will excess magnesium be removed from sulphuric acid during experiment'?
Excess magnesium in sulfuric acid can be removed by adding a dilute acid, such as hydrochloric acid, to convert the magnesium to soluble magnesium chloride, which can be filtered out. Alternatively, the solution can be allowed to stand so that any unreacted magnesium settles to the bottom, and the supernatant can be decanted.
How can you tell when as excess of hydrochloric acid has been added to the evaporating dish with the magnesium?
When excess hydrochloric acid has been added to an evaporating dish with magnesium, you will observe bubbling and fizzing as the magnesium reacts with the acid. Once all the magnesium has been consumed in the reaction, no more bubbles will be produced, indicating that excess acid is present.
If 250.3 L of hydrogen gas (d 0.0899gL ) reacts with an excess of nitrogen gas what mass of ammonia would be produced?
To determine the mass of ammonia produced, you first need to calculate the moles of hydrogen gas present. Then, you can use the stoichiometry of the balanced chemical equation for the reaction between hydrogen and nitrogen to find the moles of ammonia produced. Finally, using the molar mass of ammonia, you can convert moles to grams to find the mass of ammonia produced.
How do you form oleum from sulfuric acid?
Oleum is formed by dissolving sulfur trioxide gas in concentrated sulfuric acid. Sulfur trioxide can be introduced into concentrated sulfuric acid slowly and under controlled conditions to prevent excessive heat generation and to ensure proper mixing. This process results in the formation of oleum, which is a solution of sulfuric acid containing excess sulfur trioxide.
How can you get crystals from the reaction of magnesium and sulphuric acid?
To obtain crystals from the reaction of magnesium and sulfuric acid, you can follow these steps: 1) Mix magnesium ribbon with diluted sulfuric acid in a beaker. 2) Allow the reaction to occur, which will produce hydrogen gas and magnesium sulfate. 3) Filter the mixture to remove any excess magnesium or impurities. 4) Evaporate the filtered solution to allow the magnesium sulfate to crystallize and form crystals.
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.
What gives off aicds react with metals?
A gas, often hydrogen. For example.H2SO4 + Mg > MgSO4 + H2Sulphuric Acid + Magnesium > Magnesium Sulphate + HydrogenThe Hydrogen is the excess gas

Is more or less hydrogen produced when reacted with zinc insted of magnesium?
No, both magnesium and zinc produce the same amount of hydrogen when the same amounts react with excess of strong acid (on molecular base), though the second reaction is slower. The reaction equations can tell you more about why this is.Mg + 2H+ --> Mg2+ + H2Zn + 2H+ --> Zn2+ + H2
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.
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.
Excess hydrochoric acid in your stomach can be neutralized by magnesium hydroxide which forms magnesium and what?
The products are magnesium chloride and water.
What happen to the original magnesium after it has been burned?
If completely burnt (in excess of oxygen), all the magnesium will be converted to magnesium oxide.
