Which compounds represent the product(s) in the equation?
C3H8 + 5O2 ==> 4H2O + 3CO2

1.C3H8
2.502
3.Only 4H20
4.Both 4H20 and 3C02

Both

compounds in left hand side of the equation is called reactants.

compounds in right hand side of the equation is called products.

so ans is both water and carbon di oxide

Explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
