A. MeONa

Explanation:

One of the methods to prepare alkenes are eliminations.

The E2 reaction (for elimination, bimolecular) occurs when an alkyl halide  is treated with a strong base, such as hydroxide ion or alkoxide ion (RO⁻).

It is the most common mechanism that occurs for an elimination.

The methoxide ion is a strong base that will attack the neighboring hydrogen of the halide ion and will start removing H⁺ at the same time that the double bond of the alkene begins to form and the group X begins to leave.

Then, the neutral alkene is produced  when the  C – H link and X group has left  with the electron pair of the bond  C – X (mechanism in attachment).

Therefore, MeONa would be an appropiate reagent.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

they are both synthetic elements
