Answer:
CaCl2
And
potasium phosphate is a general name for salt of potassium and phosphate ions . The compounds can exist as
K3PO4 (Tripotassium phosphate)
K2HPO4 (di potassium phosphate)
KH2PO4 (mono potassium phosphate)
Explanation:
Calcium chloride salt is an ionic compound. so it contains both cations and anions. That means it has a positively charged ion and a negatively charged ion. In an ionic compound their is a transfer of electron. The valence electron or the charge ion present in an atom can be use to predict the chemical formula of this compound . Base on the compound the positive end is calcium while the negative end is chlorine .
Ca2+ and Cl-
cross multiply the charges
CaCl2
The charge of phosphate ions are (PO4)3−, (HPO4)2− and (H2PO4)−. And base on the valence electron potassium has a stable charge of +1 (K+). The phosphate ion produces the negative charge when it reacts with potassium.
If potassium goes into reaction with any of the phosphate ion it will be as follows.
K+ and (PO4)3−
cross multiply the charge as usual
K3PO4(tripotassium phosphate)
K+ and (HPO4)2−
cross multiply the charge as usual
K2HPO4(di potassium phosphate)
K+ and (H2PO4)−
cross multiply the charge as usual
KH2PO4 (mono potassium phosphate)
Answer:The volume will become less as the liquid wax cools to form solid wax.

Answer:
This question is incomplete
Explanation:
The process described in which the solution absorbs thermal energy is referred to endothermic reaction. Endothermic reaction is a reaction that absorbs heat/thermal energy.
The other two processes mentioned will have to be determined based on the options provided. However, what appears to be the case, based on the construction of the question, is that the question describes types of saturation (saturated, unsaturated and supersaturated solutions).
Saturated solution: This is a solution that contains just the amount of solute that that the solvent can dissolve and any further addition of solute will leave the solute undissolved at the floor/base of the solution.
Unsaturated solution: This is a solution that contains less solute than the solvent can actually dissolves
Supersaturated solution: This is a solution that contains more solute than the solvent can dissolve, leaving the undissolved solute around the solution.
