Ethanol contains the elements carbon, hydrogen, and oxygen. when ethanol burns, it chemically reacts with oxygen gas.

c2h6o + o2
ethanol oxygen gas

what elements will be present in the substances that are created when ethanol burns?
a.
nitrogen, sulfur, and sodium only
b.
carbon, hydrogen, and oxygen only
c.
the elements cannot be determined
d.
carbon and hydrogen only
correct answer is b i answered my own question! lol

The correct answer is Option B.

Explanation:

Every balanced chemical equation follows law of conservation of mass. This law states that mass can neither be created nor be destroyed but it ca only be transformed from one form to another form.

In a chemical reaction, total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

During a chemical reaction, the atoms on the reactant side must also be present on the product side.

For the given reactants, the chemical equation will follows:

As, the reactant side contained carbon, hydrogen and oxygen atoms only. So, the product will also contain the same atoms.

Hence, the correct answer is Option B.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

m=9
