Answer 1

Answer:

1. 0000000000000000000000000000000000000

Answer 2

Answer:

Given,

Weight of Mg = 480 gms

Molecular weight of Magnesium (Mg) = 24 u and Oxigen (O)=16 u

Magnesium (Mg) reacts with oxygen to form magnesium oxide (MgO)

The reaction is

As per the equation 48 gm Magnesium(Mg) and 32 gm Oxygen(O) produced 80 gm of MgO.

In other words, 48 gm magnesium required 32 gm of Oxygen for combustion.

therefore, to combustion of 480 gm magnesium required  of oxygen.

Mass of MgO formed in this reaction =
