Question

K + HOH ⇒ CrCl₂ + KOH ⇒

Answer 1

The chemical equation you provided is:

K + HOH ⇒ CrCl₂ + KOH

This equation represents a chemical reaction between potassium (K), water (HOH), chromium chloride (CrCl₂), and potassium hydroxide (KOH). Let's break down the reaction and discuss it in more detail.

Reactants:

- Potassium (K): Potassium is an alkali metal with the atomic number 19. It is highly reactive and is commonly found in nature as a salt. - Water (HOH): Water is a compound made up of two hydrogen atoms and one oxygen atom. It is a polar molecule and is often referred to as the universal solvent.

Products:

- Chromium chloride (CrCl₂): Chromium chloride is a compound composed of chromium and chlorine. It is commonly used in industrial processes and as a catalyst in organic chemistry. - Potassium hydroxide (KOH): Potassium hydroxide is an inorganic compound that is commonly used in the production of soaps, detergents, and other chemical products.

Reaction:

The reaction you provided can be interpreted as a double displacement reaction, also known as a metathesis reaction. In this type of reaction, the cations and anions of two different compounds switch places to form two new compounds.

In this case, potassium (K) from the first reactant combines with the hydroxide ion (OH-) from water (HOH) to form potassium hydroxide (KOH). The chromium ion (Cr²⁺) from chromium chloride (CrCl₂) combines with the chloride ion (Cl-) from water (HOH) to form chromium chloride (CrCl₂).

The balanced chemical equation for this reaction is:

2K + 2HOH ⇒ CrCl₂ + 2KOH

Please note that the equation you provided does not specify the stoichiometric coefficients, so I have assumed them to balance the equation.

I hope this explanation helps! Let me know if you have any further questions.
