Because the ions forming the compound will have to separate from each other then. As a result, ionic compounds disintigrated into a myriad of single lonely ions floating free in water (in solutions). The process is known as electrolytic dissociation.

Eletric current is co-directed movement of particles exhibiting similar charge.

Water doesn't have charged particles constituting it. No electricity.

Ionic compounds do have charged particles (i.e. ions), but those are locked within the lattice and cannot move. No electricity.

Ionic compounds in water disintegrate into free floating (capable of moving) ions (charged particles). All you have to do is get all the positive charges moving one way and all the negative ones moving the other and here you have it - electricity! That is achieved through applying external magnetic field.

This is why ionic compunds can conduct electricity when dissolved in water or melted.

VikaD [51]

You can differentiate between ionic, covalent and molecular compounds by the fact that ionic compounds contain elements that include both a metal and a nonmetal. Molecular compounds contain both non metals covalently bonded to each other. While acids most often on their chemical formula start with the element of Hydrogen - H.

For Eg - sulphuric acid
H2SO4
hydrochloric acid - HCl.

Select the molecule where free rotation around one or more bonds is not possible. Group of answer choices N2H4 C2Cl4 NH3 C2H6 CC

Alexandra [31]

Answer:

C₂Cl₄

Explanation:

To know if free rotation around a bond in a compound is possible, we need to see the structure of the compound (picture in attachment).

In single bonds, which are formed by σ bonds, the atoms are not fixed in a single position, and free rotation is permitted.

Double and triple bonds are formed by a σ bond and one or two π bonds, respectively. These bonds do not allow rotation, since it is not possible to twist the ends without breaking the π bond.

The chloroethylene (C₂Cl₄) has two carbons with an sp2-sp2 hybridization, they are bonded together by a double bond. <u>Free rotation on this bond is not possible, because six atoms, including the carbon atoms, doubly bonded and the four chlorine atoms bonded to them, must be on the same plane. </u>

Water molecules have __________ than molecules of similar size, such as ammonia and methane, reflecting its capacity to absorb l

Flura [38]

Given what we know, the ability of water to absorb more heat than the other substances mentioned is a reflection of its high boiling point.

<h3>What do we mean by boiling point?</h3>

This is the temperature at which the substance boils, and subsequently evaporates. Having a higher boiling point means that the substance will be able to absorb much more heat than that of a substance with a lower boiling point.

Therefore, Water molecules have a higher boiling point than molecules of similar size, such as ammonia and methane, reflecting its capacity to absorb large amounts of heat.

What is the name of the molecule that is used to heat most of our buildings?<br><br> (Chemistry)

mario62 [17]

Answer:

Fluids (air/water) either as water vapour or oxygen and carbon dioxide.

Explanation:

Heat transfer occurs through conduction, convection or radiation.

Many aties, this involves fluids whose molecules have been activated by heated by heat, moving from hotter to cooler regions, allowing for heating or cooling of the rooms.

Building materials have varying conductivity.
