The reaction is between Mg and O2.
2Mg+O2->2MgO
+2 for Mg -2 for O
Double bond Mg=O
well Mg is an element ( I Magnesium) and O is oxygen hence MgO is definitely a molecule not an atom ...
the final formula of magnesium oxide is MgO.
Mg grams -> (use Mg's molar mass) -> Mg moles -> (use ratio of moles - use balanced equation) -> MgO moles -> (use MgO's molar mass) -> grams MgO set up the equation: Mg + O2 --> MgO (we know the product is MgO and not MgO2 because magnesium has a charge of 2+ while oxygen has a charge or 2-) balance the equation: 2Mg + O2 --> 2MgO Molar mass of Mg: 24.31 g/mol Molar mass of MgO: 44.30 g/mol (add the molar mass of Magnesium - 24.31g/mol and the molar mass of Oxygen - 15.99g/mol together) (use periodic table to find these) 7.0 grams of Mg To find the moles of Magnesium you use the molar mass of Mg. (7.0 g Mg)*(1 mol Mg / 24.31 g Mg) =0.2879 moles Mg notice how the grams cancel to leave you with moles - remember dividing by a fraction is the same as multiplying by the reciprocal Now use the balanced equation's coefficients and the moles of Mg to determine the number of moles of MgO present. 2Mg + O2 --> 2MgO 2 moles Mg : 2 moles MgO -> divide both sides by 2 and it obviously becomes a 'one to one' ratio. This means that the number of moles of Mg is equal to the number of moles of MgO. This means that there are 0.2879 moles of MgO. Now that we know MgO's molar mass and the number of moles of MgO we have, the grams of MgO produced can be determined. (0.2879 moles MgO)*(44.30 g MgO / 1 mol MgO) = 12.75 grams MgO
2! Mg and O
+2 for Mg -2 for O
No, magnesium oxide is a compound made of the elements magnesium (Mg) and oxygen (O).
Double bond Mg=O
They are NOT, Mg (metal) and O2 (bi-atomic gas) are elements and not compounds,BUTMagnesium oxide ( Mg=O ) is an ionic compound
"MgO" is magnesium oxide and "H" is hydrogen, as in "Mg + H(2)O => MgO + H(2)" MgO + H2 ---> H2O + Mg
Mg + O ----> MgO
No. MgO is a compound called magnesium oxide. It is composed of two elements: magnesium and oxygen.Hint: if the chemical formula contains more than one capital latter than the substance is not an element.
well Mg is an element ( I Magnesium) and O is oxygen hence MgO is definitely a molecule not an atom ...
The cation,Mg 2+andthe anion,O 2-combine to form,MgO------------------magnesium oxide
+2 for Mg and -2 for O
the Lewis formula for MgO is Mg2+[O]2- Which mean Mg loses 2 electrons and O gains 2 electrons to be stable.
