Question

can someone plz explain me the chemical reactions like- 4Na + O= 2Na2O​

Answer 1

Answer:

here are all cemical formulas

hope it helps you

the answer is 4Na + O2 → 2Na2O. Sodium (Na) gains oxygen and gets oxidised to sodium oxide (Na2O).

Answer 2

4Na+o2=2Na2o

4 atoms of Na does not change into 2

As reactant you have 4Na = 4 atoms Na

As a product you have 2Na2 = 4 atoms Na.

The substances sodium (Na), oxygen (O2), and sodium oxide (Na2O) participate in this chemical reaction: 4Na + O2 → 2Na2O.

"Mass can be neither created nor destroyed", therefore you can't have more mass on one side than another.

When sodium is heated in excess of oxygen or air, sodium peroxide (Na2O2) is the product.

2Na + O2 = 2Na2O2.

When the reaction is carried out with a limited supply of oxygen or air, the major product will be sodium oxide.

4Na + O2 = 2Na2O.
