How many moles of MgO are produced from 11.2 L O2?
The answer is o,5 moles MgO.
Empirical formula of a compound containing 60.3 percent magnesium and 39.7 percent oxygen?
MgO
What is the chemical equation for Magnesium Oxide with Hydrogen?
"MgO" is magnesium oxide and "H" is hydrogen, as in "Mg + H(2)O => MgO + H(2)" MgO + H2 ---> H2O + Mg
What are the oxidation numbers of the elements found in MgO?
+2 for Mg and -2 for O
Is mgo ionic or covalent bonding?
Ionic. because a metal(Mg) + a non-metal (O).
If some magnesium oxide had escaped from The Crucible would the percentage composition calculation of magnesium be too high or too low?
The percent of Mg calculated will be too high. Let's say that you reacted 1.00 g of Mg and made some MgO, but so much MgO escaped as smoke that only 1.00 g of MgO was left. You would then conclude from the numbers that the mass of O in the MgO was zero! This would lead you to conclude that the percent of Mg in the MgO was 100 %, which is silly and clearly in error. Although this is an extreme example, it illustrates that the loss of MgO as smoke from the crucible leads to a percent of Mg (calculated) that is above the expected 60.3 %.
What is the percent composition in magnesium in MgO?
60%
How many moles of MgO are produced from 11.2 L O2?
The answer is o,5 moles MgO.
Mg-O bond in MgO?
Double bond Mg=O
What is Lewis formula for MgO?
the Lewis formula for MgO is Mg2+[O]2- Which mean Mg loses 2 electrons and O gains 2 electrons to be stable.
What is the percent composition of magnesium Mg in MgO?
60%
Is MgO a atom or molecule?
well Mg is an element ( I Magnesium) and O is oxygen hence MgO is definitely a molecule not an atom ...
Why is it important to add water to a heated crucible when obtaining the mass of MgO?
Pure MgO will absorbe water from the air causing an error in the experiment if that extra mass is not accounted for. By adding water in the very beginning you eliminate this error.
What is the chemical formula for Magnesium Oxide?
the final formula of magnesium oxide is MgO.
Empirical formula of a compound containing 60.3 percent magnesium and 39.7 percent oxygen?
MgO
What is the chemical equation for Magnesium Oxide with Hydrogen?
"MgO" is magnesium oxide and "H" is hydrogen, as in "Mg + H(2)O => MgO + H(2)" MgO + H2 ---> H2O + Mg
Symbol equation for magnesium oxide?
Mg + O ----> MgO
