Helen [10]3 years ago
4 0

Answer:

When magnesium burns, it combines with oxygen (O2) from the air to form magnesium oxide (MgO) according to the following equation: 2Mg(s) + O2(g) → 2MgO(s) ... Thus, a reduction half reaction can be written for the O2 as it gains 4 electrons: O2(g) + 4e− → 2O.

Mkey [24]

mass = 12.2 kg

Explanation:

To find the mass we use the following formula (Newton's Second Law of Motion):

force = mass × acceleration

mass = force / acceleration

mass = 2.32 N / 0.19 m/s²

mass = 12.2 kg
