Answer:
a) common ion effect
b) solubility
c) saturated solution
d) solubility product constant
e) molar solubility
Explanation:
When a substance, say BA2 is dissolved in a solution and another substance CA2 is dissolved in the same solution. The solubility of BA2 is decreased due to the addition of CA2. This is known as common ion effect.
The mass of a substance that will dissolve in a given Volume of solvent is known as it's solubility.
The molar solubility is the amount of moles of solvent that dissolves in 1 dm^3 of solvent.
A solution that contains just as much solute as it can normally hold at a given temperature is known as a saturated solution.
Lastly, the product of molar solubilites raised to the power of the molar coefficient is know as the solubility product constant.
Answer:
On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left.

Answer:
The correct option is D
Explanation:
The major raw material used in making cement clinker is limestone. This limestone is usually mixed and heated with clay and can sometimes be mixed, in addition to the clay, with fly ash, black ash, bauxite, iron ore and gypsum. <u>However, the product cement clinker contains different calcium silicates and/or aluminates such as Ca₃SiO₅, Ca₃Al₂O₆, Ca₂(Al,Fe)₂O₅ and Ca₂SiO₄</u>. Thus, the correct option is D.
Answer: 1.47
Explanation:
The combined gas equation when pressure is constant:
where,
=original number of moles of air in the balloon = ?
= number of moles of air in the heated balloon = ?
= initial volume of gas = 
= final volume of gas = 
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get the final pressure of gas.
Therefore, the ratio of the number of moles of air in the heated balloon to the original number of moles of air in the balloon is 1.47
