Magnesium and oxygen combine in the ratio of 3: 2 by mass to form magnesium oxide.

What type of reaction is 2Mg O2 → 2MgO?

The given reactions is an example of an oxidation reaction.

What type or class does the following reaction fall into MgO → MgO?

Answer: Exothermic reaction. Explanation: Exothermic reaction : Those reactions in which heat energy is evolved are known as exothermic reactions while the reactions in which heat energy is absorbed is known as endothermic reactions.

What is MgO?

Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2− ions held together by ionic bonding.

What kind of reaction takes place in the formation of MgO exothermic or endothermic explain?

We can conclude that it is an exothermic process by taking account of following point. The product formed that is magnesium oxide is very stable when it is lower in energy than the reactant.It is a combustion reaction which is always an exothermic reaction.

What is the balanced equation for the reaction of magnesium and oxygen?

The equation is: Magnesium + oxygen → magnesium oxide. 2Mg + O2 → 2MgO.

What is the product of the combination reaction that occurs when magnesium metal reacts with oxygen gas?

When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide. This specific combination reaction produces the bright flame generated by flares.
