Zinc metal displaces oxygen from zinc(ii)oxide however it is unable to displace oxygen from magnesium oxide.Explain

d=m/V=8/2=4(g/ml)=4(g/cm3)

17g

a) Yes electrolysis of Nickel chloride can produce Nickel metal. b) No, Since the magnesium metal has displaced the magnesium ions (magnesium in solution) from the solution, this is a...

Grams of magnesium oxide=6.05g

In the reaction of magnesium oxide with oxygen in addition to a small amount of nitride: 2Mg + O2 = 2MgO 3Mg + N2 = Mg3N2 To obtain the target...

Given Moles of Mgo is 0.15 moles . Mg react with O2 and form MgO .2 mole of Mg gives 2 mole of Mgo .So 0.15 moles of Mg Gives...

Solution:The balanced chemical equation:2Mg + O2 → 2MgOAccording to the chemical equation: n(Mg)/2 = n(O2) = n(MgO)/2Molar mass of Mg is 24 g/mol.Moles of Mg = 10.8 g × (1...

Mass of magnesium oxide is:14.70-8.90=5.80

In order to solve this task, the mass of newly formed oxide is required.

Solution: 2Mg(s) + O 2 (g)  2MgO(s)
