Answer:
21.28 grams solute can be added if the temperature is increased to 30.0°C.
Explanation:
Solubility of solute at 20°C = 32.2 g/100 grams of water
Solute soluble in 1 gram of water = 
Mass of solute in soluble in 56.0 grams of water:

Solubility of solute at 30°C = 70.2g/100 grams of water
Solute soluble in 1 gram of water = 
Mass of solute in soluble in 56.0 grams of water:

If the temperature of saturated solution of this solute using 56.0 g of water at 20.0 °C raised to 30.0°C
Mass of solute in soluble in 56.0 grams of water 20.0°C = 18.032 g
Mass of solute in soluble in 56.0 grams of water at 30.0°C = 39.312 g
Mass of of solute added If the temperature of the saturated solution increased to 30.0°C:
39.312 g - 18.032 g = 21.28 g
21.28 grams solute can be added if the temperature is increased to 30.0°C.
All acids contain OH in their formula
Answer:
"Electronegativity" decrease moving from the bottom of Group 3 to the top of Group 3
Explanation:
Electronegativity of an element tell us about the ability of an atom to attract the electrons towards the atom. It depends upon the atomic number and also the distance between the valence electrons that is present in the charged nucleus. The electronegativity will increase from left to right while moving in the periodic table. Electronegativity decreases from bottom to top. To measure the electronegativity pauling scale is used.
