How many moles of magnesium oxide are formed when 4 moles of magnesium react with oxygen Here is the formula 2 Mg plus O 2 is equal to 2 Mg O?
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.

What is the binary formula for magnesium nitride?
MgO. Magnesium typically has a 2+ charge, and oxygen typically has a 2- charge. Since the charges are opposite, magnesium and oxygen join in equal numbers to form magnesium oxide, as suggested by the chemical formula above. And since it cannot be reduced, it is also the empirical formula.
When methane burns carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
How much magnesium sulphide can be made from 1.0gram of magnesium and 1.0gram of sulphur?
The formula of magnesium sulphide is MgS, showing that a formula unit has one atom of each element. The gram atomic mass of magnesium is 24.305 and that of sulphur is 32.06. Therefore, when magnesium and sulphur are present in equal amounts by mass, sulphur is the limiting reactant. 1.0/32.06 or 0.031 moles of sulphur atoms are present. Therefore, the maximum amount of MgS that can result from reaction is 0.031 formula units of MgS. The gram formula mass of MgS is 56.365, so that 0.031 formula units of MgS will have a mass of 1.7 grams, to the justified number of significant digits.

What does magnesium plus chlorine equal?
Magnesium plus chlorine react to form magnesium chloride, a white crystalline compound with the chemical formula MgCl2. This compound is commonly used as a supplement to provide magnesium to the body or as a de-icer for roads and sidewalks.
Magnesium oxide decomposes into magnesium and oxygen If 16.12 of magnesium oxide decomposes to form 9.72 of magnesium what mass of oxygen gas is also released in the reaction?
To find the mass of oxygen gas released, we can first find the mass of magnesium in 16.12 g of magnesium oxide (molar mass of MgO = 40.31 g/mol) and then subtract it from 9.72 g to find the mass of oxygen. Find the moles of magnesium in 16.12 g of MgO: 16.12 g / 40.31 g/mol = 0.4 mol Mg Mg and O are in a 1:1 molar ratio in MgO, so 0.4 mol of Mg is equal to 0.4 mol of O Calculate the mass of oxygen: 0.4 mol x 16 g/mol = 6.4 g Therefore, 6.4 g of oxygen gas is also released in the reaction.
When methane burns carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?

How many formula units make up 21.2g of magnesium chloride Mg Cl 2?
To calculate the number of formula units in 21.2g of magnesium chloride (MgCl2), first calculate the molar mass of MgCl2 which is 95.21 g/mol. Then, divide the given mass by the molar mass to get the number of moles (0.223 mol). As there is one mole of MgCl2 in 1 formula unit, 0.223 mol is equal to 0.223 formula units.
