Question

2Mg + O2 = 2MgO where is 2 of o gone???​ if it in balanced then plz explain me how...​ and if it is added to form 2MgO then it should be 2+2 4​

Answer 1

Answer:

It is a balanced equation.

Explanation:

Here, we will apply same rule which we used to apply in mathematics -"The rule of taking common".On the product side of equation 2 is taken as common with respect to Mg and O both. Hence, It is Balanced Equation.

Hope , it helps you.

Answer 2

Explanation:

Bro it didn't go anywhere the O in the reactant side is for the oxygen molecule,which exists in nature as O2 it cannot exist in nature as O only because it will not be stable,while the reaction is being done they react to form magnesium oxide,Now it is written 2 magnesium oxide because no of atkms on lhs = no of atoms on rhs

the main point is that oxygen always exists as 02 in nature but while reacting it splits into 2 different atoms and when reaction is done Mg reacts first with 1 oxygen atom,now the second atom of oxygen is also utilized in the reaction so it is shown in balancing that 2 magnesium and 2 oxygen atoms are present.

after the reaction the oxygen doesn't remain o2 molecule but becomes ions so there is no 02 molecule
