<span>Copper II Sulfate- Cu 2+ and a sulfate SO4 2- add together nicely to make CuSO4. </span>
Explanation:
The nomenclature of ionic compounds is given by:
1. Positive is written first. And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
1.) : Calcium chloride (Correct)
In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.
2.) : Copper (II) oxide (Incorrect)
In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.
3.) : Lead (II) sulfide (Incorrect)
In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.
Its C. It has to be equivalent to the number divided or multiplied by 5.
Answer:
Temperature
Explanation:
The kinetic energy is proportional to the temperature. That is, temperature is a measure of the kinetic energy of atoms and molecules that are part of a system.
This can be explained by kinetic theory.
2.
move constantly
3.
solid - definite shape and volume
liquid - only definite volume
gas - none.
4.
The particles of gases have large interparticular space between them and they move constantly and sometimes these particles move away leading to change in volume but in case of solids the particles are packed tightly with low interparticular spaces and high interparticular force.
5.
