That is choice A.

The products are different from the reactants.

This may be easy to see - for example when one of the products is precipitated, like when you add BaCL2 to Na2SO4.  The BaSO4 formed is insoluble in water and appears as a white precipitate.

When elemental boron, B, is burned in oxygen gas, the product is diboron trioxide. If the diboron trioxide is then reacted with
zalisa [80]

<u>Answer:</u> The chemical equation is written below.

<u>Explanation:</u>

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.  

The chemical equation for the reaction of elemental boron and oxygen gas follows:

4B+3O_2\rightarrow 2B_2O_3

By Stoichiometry of the reaction:

4 moles of elemental boron reacts with 3 moles of oxygen gas to produce 2 moles of diboron trioxide.

The chemical equation for the reaction of diboron trioxide and water follows:

B_2O_3+3H_2O\rightarrow 2H_3BO_3

By Stoichiometry of the reaction:

1 mole of diboron trixoide reacts with 3 moles of water to produce 2 moles of boric acid.

Hence, the chemical equations are written above.
