Question

Balance this equation _ Mg + O2 = MgO ​

Answer 1

$\small{\underline{\sf{\blue{Answer-}}}}$

Given equation _

$\green{\sf{\longmapsto Mg+ O_{2}\longrightarrow MgO}}$

The balanced chemical equation for the reaction is __

$\green{\sf{\longmapsto 2Mg+ O_{2}\longrightarrow 2MgO}}$

We can be sure that this reaction is balanced.

Since,

• 2- Magnesium on both sides

• 2- Oxygen on both sides

Steps of balancing a chemical equation :-

1.At first, identify each element found in the equation.

2. Then identify the net charge on each side of the equation.

3. Try to start with an element found in one compound on each side of the equation,if it’s possible. Change the coefficients (the numbers in front of the compound or molecule).

4. After balancing one element, you need to do the same thing with another element.

5. At last, check your work to make certain the charge on both sides of the equation is also balanced.

Note-1:-

The number of atoms of each type of atom must be the same on each side of the equation once it has been balanced.

Note-2 :-

You need to change the coefficients, not the subscripts in the formulas.

Note-3:-

The net charge must be the same on each side of the equation once it has been balanced.
