Some covalent compounds dissociate into ions in water. What atom do these compounds have in their structures? What type of solut
valentina_108 [34]

H atoms are found in the molecules of covalent compounds that dissolve in water. These compound are called acids (proton donors). They form acidic solutionst{acidic solutions} acidic solutions.

Because there are no ions moving about in solution with covalent molecules, they are characterised as non-electrolytes. Non-electrolyte solutions are those that do not conduct electricity.

Examples are hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid solutions (HNO3).

<h3>What type of compounds dissociate in water to form ions?</h3>

When certain substances dissolve in water, they undergo either a physical or a chemical change that results in the formation of ions in solution. These substances are members of an important class of compounds known as electrolytes. Nonelectrolytes are substances that do not produce ions when dissolved.

A substance is known as a strong electrolyte if the physical or chemical process that generates the ions is essentially 100% efficient (all of the dissolved compound yields ions). A weak electrolyte is one in which only a small portion of the dissolved substance undergoes the ion-producing process.

Write a balanced chemical equation based on the following description:
kupik [55]

The balanced chemical equation for the reaction is

<h3>6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) +  N₂(g) </h3>

From the question given above, we were told that:

solid cesium reacts with solid cesium nitrite to form solid cesium oxide and nitrogen gas.

The equation for the reaction can be written as follow:

Caesium => Cs

Caesium nitrite => CsNO₂

cesium oxide => Cs₂O

nitrogen gas => N₂

Caesium + Caesium nitrite —> Caesium oxide + Nitrogen gas

<h3>Cs + CsNO₂ —> Cs₂O +  N₂</h3>

The above equation can be balance as follow:

Cs + CsNO₂ —> Cs₂O +  N₂

There are 2 atoms of N on the right side and 1 atom on the left side. It can be balance by writing 2 before CsNO₂ as shown below:

Cs + 2CsNO₂ —> Cs₂O +  N₂

There are 2 atoms of Cs on the right side and a total 3 atoms on the left side. It can be balance by writing 6 before Cs and 4 before Cs₂O as shown below:

6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) +  N₂(g)

Now the equation is balanced
