Explanation:
The Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines. Traditionally, the reaction uses potassium phthalimide. ... The alkylation of ammonia is often an unselective and inefficient route to amines. In the Gabriel method, phthalimide anion is employed as a surrogate of H2N−.
Answer:
Burning wood
Explanation:
the fire releases heat into the air from the burning wood
Electrons fill the electron orbitals (s, p, d, or f) starting from the lowest energy level going to the highest energy level.

ANSWER

EXPLANATION
Given that;
The two reactants are KBr and CaO
Double replacement reaction is a type of chemical reaction that occur when two reactants exchange cations and anions to yield new products.

Therefore, the resulting products of the given data are K2O + CaBr2
The correct answer is option B
