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 )

A chemist reacts 30.0 mL of 5.6 M HCl with an excess of Mg(OH)2. How many grams of magnesium chloride will be produced?
8 g of magnesium chloride is obtained.
How do you form oleum from sulfuric acid?
Dissolve excess Sulfur trioxide in concentrated Sulfuric acid
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.
Affects of magnesium carbonate?
Magnesium carbonate acts as an antacid. Therefore,it neutralises excess of hydrochloric acid in stomach.
In the reaction Mg (s) plus 2HCl (aq) H2 (g) plus MgCl2 (aq) how many grams of hydrogen gas will be produced from 125.0 milliliters of a 6.0 M HCl in an excess of Mg?
0,75 grams hydrogen
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
How tp prepare magnesium acetate?
when a piece of Magnesium is added to acetic acid bubbles of H2 gas are produced and solution becomes milky now evaporate the excess acid and water by heating and get solid Magnesium acetate.

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.

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.
