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.

D = 24 g/ml<br> v = 1200 ml<br> m = ?
8_murik_8 [283]

Answer:

<h2>28,800 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question we have

mass = 24 × 1200

We have the final answer as

<h3>28,800 g</h3>

Hope this helps you

There are on average 43 g of sugar and 355 mL can of soda please calculate the molarity of sugar in the can of soda the molar ma
vfiekz [6]

Explanation:

Given :

Amount of solute - sucrose (C12H22O11) = 41 g

Amount of solvent -soda  = 355-mL

Molarity of the solution with respect to sucrose= ?

Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.

Formula to find the molarity of solution :

               Molarity =  

Amount of solvent is given in mL, let’s convert to L :

               1 L = 1000 mL

Therefore, 355 mL in L will be :

                   

               = 0.355 L

We have the amount of solute in g, let’s calculate the number of moles first :

       Number of moles (n) =  

Molar mass of C12H22O11 = 342.29 g/mol.

Therefore, n =  

               = 0.119 moles.
