What is the mass number for Mg?
Magnesium is a metal element. Mass number of it is 24.
Can magnesium's mass be 24 after rounding it off?
Yes
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?
16.12-9.72=6.40g
Magnesium oxide decomposes into magnesium and oxygen If 4.03 of magnesium oxide decomposes to form 2.43 of magnesium what mass of oxygen gas is also released in the reaction?
4.03g - 2.43g = 1.60g
When magnesium burns in pure nitrogen gas magnesium nitride is formes what mass of magnesium must be provided in order to produce 1.19 grams of magnesium nitride?
3Mg + N2 --> Mg3N2 molar mass of Mg3N2: 100.9494 g/molmolar mass of Mg: 24.305 1.19g Mg3N2 * 1mol/100.9494g * 3mol Mg/1mol Mg3N2 * 24.305g/1mol = 0.860g
What is the chemical name for Mg3N3?
The chemical name for Mg3N2 is magnesium nitride.Mg = MagnesiumN = NitrogenIts molar mass is 100.9494 g/mol.
What is the molar mass of magnesium nitride (Mg3N2) if the molar mass of magnesium is 24.31g and nitrogen is 14.01g?
Need formula of magnesium nitride, an ionic compound. Mg2+ and N3- together make Mg3N2 -------------- so 3 * 24.31 g = 72.93 grams 2 * 14.01 g = 28.02 grams ------------------------------------------add = 100 .95 grams/mole --------------------------------molar mass magnesium nitride
HOW TO GET percent of magnesium by mass?
You take the mass and divide it by the total mass of the element. Magnesium by itself is 100%.
When magnesium is burned in air is the product formed heavier lighter or the same mass as the magnesium that you started with?
Both products MgO (magnesium oxide) and some Mg3N2 (magnesium nitride)are both much heavier than the originating Mg strip before it was set to fire.Mg = 12 g/molMgO = (12+16) = 28 g/mol(1/3)Mg3N2 = (1/3)*(3*12 + 2*14) = 0.33*64 = 21 g/mol
What happens to the temperature when the mass is increased in a chemical reaction involving magnesium and hydrochloric acid?
The temperature will increase the higher the mass of magnesium you add. It will increase the rate of the reaction.
What is the percent composition of magnesium (mg) on MgO?
60%
If the surface of the Mg ribbon you used were covered with thin oxide coating prior to the reaction would your mass percent calculation of magnesium be too high or too low explain?
higher..
What 4 elements make up 95 percent of the earth's mass?
Iron, Oxygen, Silicon, and Magnesium
What is the percent of adults in Libya have a higher education?
