Is it possible to have more atoms on the product side of a chemical reaction than there are on the reactant side? Explain why or why not.

No, you cannot.

Explanation:

Due to the Law of Conservation of Energy all chemical equations have to be balcned. The Law of Conservation of energy states that matter cannot be neither created nor destroyed. By having more atoms on either side, you are breaking this law.  

its first and third is your answer i did the qustion the fourth isnt right

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
