Answer:

Electrolytes are chemicals that break into ions (ionize) when they are dissolved in water. The positively-charged ions are called cations, while the negatively charged ions are called anions.  

Strong electrolytes completely ionize in water. This means 100% of the dissolved chemical breaks into cations and anions.

Weak electrolytes partially ionize in water. Pretty much any dissociation into ions between 0% and 100% makes a chemical a weak electrolyte, but in practice, around 1% to 10% of a weak electrolyte breaks into ions.

If a substance doesn’t ionize in water at all, it’s a nonelectrolyte.

What type of solution has the capacity to dissolve more solute?
AfilCa [17]

Answer:

The answer to this is

Unsaturated solution

Explanation:

An unsaturated solution has the property of having a solute concentration lower than the the solubility at equilibrium at a given temperature hence it has the capacity to  dissolve more solutes. Is is a solution containing a lower amount of solute than a saturated solution

The two processes that occur on dissolving a solute in a solvent are dissolution and crystallization and in an unsaturated solution the rate of dissolution is greater than the rate of crystallization

Explain how to convert a mass of compound A to a mass of compound D in words with no equations using the following reaction 2A +
leonid [27]

Answer:

Explanation:

The given reaction equation is:

                2A + 4B → C + 3D

We know the mass of compound A in the reaction above. We are to find the mass of compound D.

We simply work from the known mass to calculate the mass of the unkown compound D

Using the mole concept, we can find the unknown mass.

Procedures

  • We first find the molar mass of the compound A from the atomic units of the constituent elements.
  • We then use the molar mass of A to calculate its number of moles using the expression below:  

            Number of moles of A = \frac{mass of A}{molar mass of A}

  • Using the known number of moles of A, we can work out the number of moles of D.

           From the balanced equation of the reaction, it is shown that:

         2 moles of compound A was used up to produced 3 moles of D

  Then \frac{3}{2} x number of moles of A would give the number of moles of D

  • Now that we know the number of moles of D, we can find its mass using the expression below:

             Mass of D = number of moles of D x molar mass of D

Hydrates that have a low vapor pressure and remove moisture from air are said to be ___. Question 8 options: effloresce hygrosco
-Dominant- [34]

Answer:

Hygroscopic

Explanation:

An hygroscopic substance is one that absorbs moisture from the atmosphere and becomes wet. Their ability to remove water from air is less than that of deliquescent substances. Most of the solid hygroscopic substances forms pasty substances and not solutions like the deliquescent compounds.

Examples are sodium trioxonitrate(v), copper(ii) oxide e.t.c

Efflorescence compounds gives off their water of crystallization to the atmosphere.

For questions #8 – 9 use the following pictures:
Annette [7]
8. The picture that would best represent atoms in the gas of a neon sign is the image B. This is because they have room for movement in that their distance between each particle is great. That is why gases has greater volume compared to liquids and solids.

<span>9. The picture that would best represent a rock is the image C. The solid molecules are so pact that they have no room for movement.</span>
