That comes from the adding oxide. 2 Mg + O2 = 2 MgO. Burning is oxidation.

When a substance is heated, it gains thermal energy. This increased energy causes the substance's particles to move faster and its temperature to rise.
When magnesium is burned, it combines with oxygen from the air to form magnesium oxide. This reaction increases the overall weight of the magnesium because the newly formed magnesium oxide has a greater mass than the original magnesium metal due to the added oxygen atoms.
The first electron affinity of magnesium is exothermic. This means that energy is released when a neutral magnesium atom gains an electron to form a magnesium ion.
Matter gains energy when it is heated due to a thermal transfer. It does not always evaporate when heated as this varies based on the specific material being heated.
The valency of magnesium in magnesium sulfate is +2, as magnesium typically forms ions with a charge of +2. Sulfate (SO4) has a valency of -2 because it usually gains two electrons to achieve a stable octet.
It gains an extra "r" in the noun form, as "referrals".
The chemical formula for magnesium oxide is MgO. Magnesium has valency +2 and oxygen has -2. So, magnesium donates two electrons and oxygen gains two electrons to form ionic bond.The chemical formula for strontium oxide is SrO. Strontium has valency +2 and oxygen has -2. So, strontium donates two electrons and oxygen gains two electrons to form ionic bond.
Extra ordinary gains is shown in income statement of the company and it is not shown in the balance sheet of the company.
