How do you calculate what mass of magnesium chloride is formed when 54.75g of HCl is reacted with sufficient magnesium?
By starting with a balanced equation. Mg + 2HCl -> MgCl2 + H2 when they say sufficient magnesium they imply that magnesium is in excess and HCl limits and drives the reaction, or that both are equal in molarity/mass 54.75 g HCl (1 mole HCl/36.458 g)(1 mole MgCl2/2 mole HCl)(95.21 g/1 mole MgCl2) = 71.49 grams magnesium chloride produced -----------------------------------------------------------
How do you separate magnesium chloride MgCl2 from AgCl?
Since magnesium chloride is highly soluble in water, and Silver Chloride has low solubility in water, try diluting with excess water, and filter out the AgCl.
In the reaction of silver nitrate with sodium chloride how many grams of silver chloride will be produced from 100 g of silver nitrate when it is mixed with an excess of sodium chloride?
58.9g
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 ) --------------------------------------------------
In the reaction MgCI2 plus 2KOH Mg(OH)2 plus 2KCI if 3 moles MgCI2 are added to 4 moles KOH what determines how much Mg(OH)2 is made?
The potassium hydroxide is what we call the limiting reactant. 4 moles of potassium hydroxide react with 2 moles of magnesium chloride. The third mole of magnesium chloride is in excess and has no effect.
Excess hydrochoric acid in your stomach can be neutralized by magnesium hydroxide which forms magnesium and what?
The products are magnesium chloride and water.

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.

When 4 moles of aluminum are allowed to react with an excess of chlorine gas Cl2 how many moles of aluminum chloride are produced?
4 moles
What is the theory yield of magnesium chloride when 5.6 grams of magnesium is reacted with elemental chlorine there is an excess of elemental chlorine the 5.60g magnesium is the limiting reactant?
magnesium + chlorine --> magnesium chloride Mg (s) + Cl2 (g) --> MgCl2 (s) 5.60 g Mg x 1 mol Mg x 1 mol MgCl2 x 95.21 g MgCl2 = 21.9 g MgCl2 ..................24.31 g Mg. 1 mol Mg........ 1 mol MgCl2
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.
What happens when chloride is taken in excess?
vomitting
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
What is the equation of magnesium nitrate with an excess of sodium phosphate to make sodium nitrate and magnesium phosphate.?
no reaction
