Answer:
Opposite poles of attract each other and make bonds.
Explanation:
Those compounds are soluble in water which have polar nature means that make poles with other atoms while on the other hand, those compounds which doesn't have polar nature are dissolve in non-polar solvent. The polar nature of compounds is due to their difference in electronegativities so in polar compounds opposite poles attract one another and make bonding with each other.

Answer:
Ternary
Explanation:
A ternary ionic compound is an ionic compound composed of three or more elements. Copper II Nitrate is a ionic compound and contains 3 elements thus making it Ternary
Answer:
2.28 M
Explanation:
Step 1: Given data
Percent by mass (%m/m): 20.0 %
Density (ρ): 1.114 g/mL
Step 2: Calculate the percent by volume (%m/v)
We will use the following expression.
Step 3: Calculate the moles of solute in 100 mL of solution
The molar mass of phosphoric acid is 97.99 g/mol. The moles corresponding to 22.3 g are:
Step 4: Calculate the molarity of the solution
0.228 moles of solute are in 100 mL (0.100 L) of solution. The molarity of the solution is:
