B.Several chemical changes occurred. I conclude that a chemical reaction took place
Explanation:
From the observation, Jason can conclude that several chemical changes occurred and a chemical reaction has taken place. In a chemical change, often times, new products are usually formed.
- A chemical change is one in which new kind of matter is formed.
- Chemical changes are products of chemical reactions.
- The rearrangement of atoms in reacting species and the formation of bonds leads to chemical reactions.
- Chemical changes are irreversible, no change in mass(mass is conserved) and they require considerable amount of energy.

Answer:
The phosphorus ylide reacts with the aldehyde or ketone to make an oxaphosphetane.
Explanation:
The Wittig reaction is a reaction that occurs between a phosphorus ylide and an aldehyde or ketone. The final products are an alkene and triphenyl phosphine oxide.
The first step in the reaction is the attack of the phosphorus ylide on the aldehyde or ketone. This is followed by attack of oxygen on phosphorus to form a [2+2] cycloaddition product (oxaphosphetane) which decomposes to form the alkene and triphenylphosphine oxide.
Carbon Dioxide, water vapor, Argon, and I think neon.
