Given 4K + O2 → 2K2O, what is the reaction type?

Single Replacement


Double Replacement

Synthesis (formation)

Decomposition

Did you replace anything? So it can't be 1 or 2.

Did you decompose anything? That is, did you take something and make smaller somethings? No
So it must be synthesis. Synthesis occurs when smaller somethings combine to make bigger somethings.
By the way I think K and O2 combine to make K2O2, potassium peroxide.

Single replacement

Well, let me put my funny hat on and try to guess the reaction type. Hmm, I would say this reaction is a synthesis (formation) type. It's like when two lonely elements, potassium (K) and oxygen (O2), decide to come together and form a beautiful compound called potassium oxide (K2O). Ah, the magic of chemistry and love!

To determine the reaction type, let's break down the given chemical equation: 4K + O2 → 2K2O

In this equation, we have potassium (K) reacting with oxygen (O2) to form potassium oxide (K2O).

The reaction involves the exchange of elements, where potassium replaces oxygen in the compound. This type of reaction is called a single replacement reaction.

Therefore, the reaction type for the given equation is single replacement.
