There are 3 grams of magnesium and 2 grams of oxygen if 4 grams of magnesium oxide is produced and all of the magnesium was used up how many grams of oxygen are left?
i dont know help :C
How many grams of oxygen gas is consumed in burning magnesium?
A balanced equation for the reaction is 3 Mg + 3/2 O2 = 3 MgO. the atomic mass of mass of magnesium is about 24.3 and that of oxygen is about 16.0; therefore the mass of magnesium oxide produced is 3 (24.3 + 16.0) = 120.9 grams. (If the specification of "3 moles" of magnesium is considered to have only one significant digit, this answer should be written instead as 1 X 102 grams.)
1.25 g of magnesium hydroxide are added to a 5.00 M solution of hydrochloric acid in a neutralization reaction that produces water and magnesium chloride How many grams of magnesium chloride are prod?
2.04 g
What would be the total mass of the products of a reaction in which 10 grams of water decomposes into the elements hydrogen and oxygen?
Also 10 grams.
How many moles of water H2O are produced from the reaction of 16 grams methane CH4 with an unlimited supply of oxygen O2. How many grams of H2O is this?
Two moles of water are produced.
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 ) --------------------------------------------------
There are 6 grams of magnesium and 4 grams of oxygen if 8 grams of magnesium oxide is produced?
2
In the reaction between magnesium and oxygen the mass of magnesium and oxygen was 2.5 grams how much magnesium oxide was formed?

18.00 grams of lithium oxide is added to 10.56g of water. when the reaction ended0.0250 grams of hydrogen gas was produced?
Answer= 4 mol H3PO4 - White Plains Public Schools
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
If an excess of nitrogen is reacted with 3.41 grams of hydrogen how many grams of ammonia can be produced?
Balanced equation first. N2 + 3H2 >> 2NH3 (hydrogen is limiting and drives the reaction ) 3.41 grams H2 (1mol/2.016g )(2mol NH3/3mol H2 )(17.034g NH3/1mol NH3 ) = 19.2 grams of ammonia produced ( this is called the Born-Haber process )
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.
How many grams of oxygen gas is consumed in burning magnesium?
