Answer:

K₃PO₄ and HBr

Explanation:

The premise of your question is incorrect.

A strong electrolyte is a substance that ionizes completely in solution.

For example, CaCO₃, is a strong electrolyte, even though it is insoluble.

Very little of it goes into solution, but every bit that does dissolve separates completely into ions.

In an ionic equation, we write it as CaCO₃(s) because it is insoluble.

An ionic equation shows soluble strong electrolytes as ions.

K₃PO₄ is a soluble strong electrolyte because salts of Group 1 metals are soluble.

HBr is a strong acid and a strong soluble electrolyte. In aqueous solution it dissociates completely into H⁺ and Br⁻.

Acetic acid is a soluble weak electrolyte. It is a weak acid, so only a few of its molecules dissociate into ions.

Which statement describes the bonds in iron sulfate, FeSO4?

Feliz [49]

___

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.

Elements form bonds to increase their stability. The main types of bonds are:

Metallic bonds: they are formed between metals and the electrons are in a delocalized cloud.
Ionic bonds: they are formed between metals (lose electrons) and nonmetals (gain electrons)
Covalent bonds: they are formed between nonmetals, which share electrons.

Regarding the bonds in FesO₄:

Fe is a metal and S a nonmetal, thus they will form ionic bonds.
S and O are both nonmetals, thus they will form covalent bonds.

Regarding the bonds in FesO₄, Fe and S have an ionic bond, while S and O have covalent bonds.

hydrogen decomposes quickly when exposed to light. the reaction for decomposing hydrogen peroxide is:

Svet_ta [14]

The decomposition reaction for hydrogen peroxide is given below:

2 $H_{2}$ $O_{2}$ → 2 $H_{2}$ O + $O_{2}$

This is a decomposition reaction.

Reactions in which a reactant breaks into two or more products are known as Decomposition reactions.

AB → A + B

here, AB represents the reactant that begins the reaction, and A and B represent the products of the reaction

The decomposition reaction of decomposing hydrogen peroxide is exothermic. When the hydrogen peroxide undergoes a decomposition reaction, heat is also released along with water and oxygen.

Hence the reaction for decomposing hydrogen peroxide is :

2 $H_{2}$ $O_{2}$ → 2 $H_{2}$ O + $O_{2}$
