Give the correct balanced equation for the single replacement reaction of magnesium with aluminum oxide

A)

Mg + AIO - MgO + Al

B)

Mg + Alz0z - M90 + AL

3Mg + Al2O3 – 3MgO + 2A

D)

Mg + A1,0- Mgo

Al

Al2O3 + 3Mg ===》 3MgO + 2Al

Explanation:

Reaction of aluminium oxide with magnesium metal would form magnesium oxide and aluminium metal.

Balancing the stoichiometric equation, the number of atoms at the reactant must be equal to the number of atoms at the product so that law of conservation of matter must hold.

Al203 + 3Mg 》 3MgO + 2Al

2 aluminium at reactant = 2 aluminium at product

3 oxygen at reactant = 3 oxygen at product

3 magnesium at reactant = 3 magnesium at product.

yup its correct its: c) b b

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
