Answer:

The correct answers is A) solvent.

Explanation:

Solubility is the ability of a substance to dissolve in another called solvent. The solubility of a solute in a given solvent mainly depends on the temperature. For many solids dissolved in liquid water, solubility increases with temperature up to 100 ° C.

In the liquid water at high temperatures the solubility of the ionic solutes tends to decrease due to the change in the properties and structure of the liquid water.

Gaseous solutes show a more complex behavior with temperature. As the temperature rises, the gases generally become less soluble in water but more soluble in organic solvents.

Hence, if we vary the temperature of the solvent we can check the effects on solubility of a solute.

Aluminum has a face-centered cubic unit cell. How many atoms of Al are present in each unit cell
Serjik [45]

Answer:4

Explanation:

As shown in the image attached, a face-centred cubic structure has 8 atoms at the corners and 6 face center atoms.

Each corner atom contributes to eight cell, so per unit cell 1/8 ×8 =1atom

Face center atoms contributes to two unit cells 1/2 × 6=3atoms

Total atoms =3+1=4atoms

Therefore the atoms in Al FCC per unit cell is 4

5. Why are lonic compounds good conductors of electricity?
ziro4ka [17]

Answer:

The options are unclear, however, the correct option is:

Aqueous solutions of ionic compounds cause to dissociate, hence, ions are free to conduct electricity

Explanation:

Ionic compounds are compounds formed from ions (charged atoms). For example, NaCl is an ionic compound from the following ions; Na+ (cation) and Cl- (anion). One characteristics of ionic compounds is their ability to dissociate into the ions that form them when in an aqueous solution i.e. NaCl will dissociate into Na+ and Cl- when in an aqueous solution.

These disssociated ions are free to conduct electricity, hence, making ionic compounds good conductors of electricity.

Only the _____ word in an organism's complete scientific name has its first letter capitalized
dimaraw [331]
Only the first word in an organism's complete scientific name has its first letter capitalized.

When writing out the organism's scientific name, it goes Genus and then species. The Genus is always capitalized and species is always lowercase. Also when writing the name, usually you either write it in italics or underline the scientific name.
