Answer:
addition of aqueous hydrochloric acid
Explanation:
The solubility of copper (ll) hydroxide in water is negligible. This implies that the substance is only slightly soluble in water.
However, the addition of aqueous hydrochloric acid leads to the following reaction;
Cu(OH)2 + 2HCl ---------> CuCl2 + 2H2O
Copper II chloride is soluble in water hence the crystals dissolve when stirred. and the molar solubility increases.

Answer:
There are 19 atom sin total in antimony silicate, 
.
Explanation:
Number of antimony atoms = 4 × 1 = 4
Number of silicon atoms = 3 × 1 = 3
Number of oxygen atoms = 3 × 4 = 12
Number of atoms in antimony silicate:
= 4 + 3 + 12 = 19
There are 19 atom sin total in antimony silicate, .
Answer:
C
Explanation:
'Ordered Arrangement' basically means that it is a solid at room temperature. Room temperature is approximately 15-20C so we are looking for melting and boiling points that are above room temperature so it hasn't/can't melt or boil at room temperature and would therefore be solid. Option C is the only one where both points are temperatures above room temperature therefore option C is the only one where the substance would be in an 'ordered arrangement' at room temperature.
Hope this helped!
