Classify the reaction between zinc and acetic acid and explain, in general terms,
Nitella [24]

Answer:

The reaction between zinc and acetic acid is a single-replacement reaction. During this type of reaction basically one element replaces one compound.

The balanced equation for the reaction between zinc and acetic acid is

Zn(OH)_2 +2CH_3 COOH ----> Zn(CH_3COO)_2+2H 2O

Or this might help too!

Balanced Chemical Equation

A balanced chemical equation is defined as the chemical equation which has an equal number of atoms on both sides of the reaction arrow. A balanced chemical equation is based on the law of conservation of mass.

Answer and Explanation:

Below is the reaction between acetic acid and Zinc:  

Z n  +  2 H C 2 H 3 O 2  →  Z n ( C H 3 C O O ) 2  +  H 2

This reaction is an example of a reaction between an acid and a metal. When an acid reacts with a metal, salt, and Hydrogen gas forms. The Hydrogen gas formed here can be tested as it burns with a POP sound.

Which of the following best describes how an ionic compound dissolves in water?
Nadusha1986 [10]

The statement that best describes how an ionic compound dissolves in water is as follows: it separates into individual molecules and is an electrolyte, which is option C.

<h3>What is an ionic compound?</h3>

Ionic compound is any compound is a chemical compound composed of ions (charged atoms) held together by electrostatic forces termed ionic bonding.

Ionic compounds are electrolytes i.e. a substance when, in solution or when molten, ionizes and conducts electricity.

For example; sodium chloride (NaCl) is an ionic compound breaks down into sodium ions (Na+) and chloride ion (Cl-).

Therefore, the statement that best describes how an ionic compound dissolves in water is as follows: it separates into individual molecules and is an electrolyte.
