When sodium and oxygen react they will produce sodium oxide. write and balance the complete chemical equation that describes this reaction.

 The  balanced chemical  equation  when sodium and  oxygen react is  as below

4 Na + O₂  → 2 Na₂O

  Explanation

From equation above 4  moles of  sodium (Na) react  with 1  mole   of oxygen (O₂)  to produce sodium oxide ( Na₂O)

Since there  is equal  number  number of atoms   in  side  of reactants  and    in the side  of product  the  equation  is balanced.

For  example there is 4 atoms of Na in side of reactant and 4  in side  of product.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
