Question

Which of the following correctly represents the synthesis of potassium oxide?

Answer 1

Answer:

$4K+O_2\operatorname{\rightarrow}2K_2O$

Explanations:

Synthesis reaction occur when two or more different molecule combine to form a difference molecule.

For synthesis of potassium oxide, we need to find the equation such that if two elements combine, they will form potassium oxide.

Potassium = K

Oxygen = O2

The synthesis reaction will be:

$4K+O_2\rightarrow2K_2O$
