mg + O2 -> Mgo what type of reaction is it
Answers
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.
The reaction of magnesium with oxygen is an exothermic reaction . Magnesium upon reaction with oxygen forms a white powder of magnesium oxide and heat energy is evolved. Magnesium oxide is represented by the formula MgO. Magnesium is very reactive in nature.
The reaction involved is :
2 Mg + O2 ---> 2MgO
Answer:
This equation is an exothermic reaction
Explanation:
2Mg + O₂ = 2MgO
In this equation, Mg is magnesium, O is oxygen, and the result is MgO, known as magnesium oxide.
This type of reaction is called a combination reaction or a synthesis reaction. Since A + B = AB, this is a combination reaction. When we see in the periodic table that magnesium is a metal and oxygen is a nonmetal, they form an ionic bond.
First, we add the number of atoms on both sides of the equation. On the product side, there is one magnesium atom, two oxygen atoms, and one magnesium atom and one oxygen atom. If nothing is written on the coefficient, we assume it is 1. This equation is not balanced. To make the oxygen equal, we need to balance the equation. To make the oxygen equal, we can put a factor of 2 in front of the MgO. We have one times two, and the oxygen in the equation is balanced. We have one magnesium in the reactant; when we balance the oxygen, we double the one magnesium, giving us two magnesium atoms. After that we add the reactant Mg to a factor of 2. Now the equation is balanced and the final equation is like this
2Mg + O₂ = 2MgO
This equation is an exothermic reaction; when you have magnesium and it ignites, it combines with oxygen and produces a bright light. And it is dangerous to the eyes if we are very close to it. In the periodic table, Mg has an ionic charge of 2+ and oxygen an ionic charge of -2; therefore, the result has a net payout of 0 since the 2+ and 2- cancel. In this reaction, solid magnesium reacts with oxygen in the air to form magnesium oxide, releasing heat.
