Lithium has charge of +1 and bromide has charge of - 1. So they combine to form the compound lithium bromide which is expressed as LiBr.
<h3><u>Explanation:</u></h3>
Lithium is an alkali metal placed in group 1 or periodic table. It has a valency of 1 which is achieved as lithium loses an electron to achieve a charge of +1.
Bromine is a halogen which is placed in group 17 of periodic table. It has a valency of 1 which is achieved as bromine looses an election to achieve a charge of - 1.
Lithium is the cation and bromide is the anion. So lithium is written in front and bromine following the cation. And as both of their valencies are 1, so they form the compound LiBr.
It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.
Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.
Boiling point of the water is 100°C.
Joule (J) is the standard unit for energy (in this example heat).
Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

Solid Solutions </span>
Solid solutions are formed only by solutes and solid solvents. In
everyday life, the main examples of this type of solution are metallic alloys.
2) Liquid Solutions
Liquid solutions have liquid solvent, usually water, and solutes can be solid, liquid or gaseous.
3) Gaseous solutions
<span>This kind of solution is formed by the only mixture of gases. Air is an
example, as its approximate composition is 78% nitrogen gas, 21% oxygen gas and
1% of other gases.</span>
Answer:
The formula for lithium acetate is CH3COOLi
Explanation:
The formula for lithium acetate is obtained by replacing the hydrogen atom bonding to the oxygen atom in acetic acid with Li as shown below:
CH3COOH + LiOH —> CH3COOLi + H2O
Answer:
<u>2.13</u> moles of AlCl3 are produced from 3.2 moles of Cl2
Explanation:
Moles : The amount of substance that contain as many particles as present in 12 grams of C-12.
The balanced equation for the reaction is :

This reaction shows the following :
2 mole Al = 3 mole Cl2 = 2 mole AlCl3
In question we are asked to calculate the moles of AlCl3 produced from Cl2
So, we will use only Cl2 andAlCl3 moles
3 mole Cl2 = 2 mole AlCl3
1 moles of Cl2 will give =
of AlCl3
3.2 moles of Cl2 will give =
of AlCl3
= 2.133 moles
