When an element reacts with a compound to produce another element and new compound, the reaction is called?

Single Replacement Reaction~

The type of reaction you are referring to is called a single displacement reaction, also known as a replacement reaction. In this type of reaction, an element reacts with a compound, displacing another element in the compound and forming a new compound.

To determine the type of reaction, you can follow these steps:

1. Write down the reactants and products involved in the reaction.
2. Identify the elements in each compound.
3. Determine if an element in the reactant compound is being replaced or displaced by another element from the element reactant.

In a single displacement reaction, the equation usually takes the form of:

A + BC → B + AC

Where A is an element, BC is a compound, B is another element, and AC is the new compound formed.

For example, let's consider the reaction between zinc (Zn) and hydrochloric acid (HCl):

Zn + 2HCl → ZnCl2 + H2

In this reaction, zinc (Zn) is displacing the hydrogen (H) in the hydrochloric acid (HCl) compound, resulting in the formation of zinc chloride (ZnCl2) and hydrogen gas (H2).

Therefore, the reaction between an element and a compound to produce another element and a new compound is called a single displacement reaction.
