Which equation has water as a product in the chemical reaction?
a. na + cl nacl
b. h2o h2 + o2
c. naoh + h2 na + h2o
d. co2 + o2 + energy c6h12o6 + o2

The right answer is c. NaOH + H2 ==> Na + H2O.

During a chemical reaction, a reaction product is a compound that results from the interaction of the reagents and is detectable at the end of the reaction.

let us take another example, during the combustion of an organic compound such as glucose (a sugar of formula C6H12O6), according to the reaction:

6CO2 + 6H2O ==> C6H12O6 + 6O2

Water (H2O) as well as carbon dioxide are reagents; while glucose and oxygen are products in this case.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic
