Answer:
the answer to the question is calcium
Calcium chloride is the most soluble salt in ice water due to its ability to lower the freezing point of water more than other salts.
When it comes to solubility in ice water, the most soluble salt would be the one that can lower the freezing point of water the most. Sodium chloride (NaCl) and its analogs calcium chloride (CaCl₂) and magnesium chloride (MgCl₂) are often used to melt ice on roads and sidewalks because they have lower freezing points than pure water. Among these salts, calcium chloride would be the most soluble in ice water. The group 2 metal salts, such as calcium chloride, dissociate to yield three particles per formula unit and provide a larger depression of the freezing point compared to sodium chloride, which dissociates to yield only two particles per formula unit.

Linear momentum is a vector quantity defined as the product of an object’s mass and it's velocity
Answer:
196 J
Explanation:
PE = mgh
PE = (10 kg) (9.8 m/s²) (2 m)
PE = 196 J
B. The heavy caffeine molecules are more likely to fall apart than the lighter CuCl2 molecules.
C. The metallic bonds in copper chloride are stronger than the ionic bonds in caffeine.
D. Caffeine is a network solid and has a low melting point like other network solids.
Option-A " The intermolecular forces holding the caffeine molecules together are weaker than the ionic bonds in CuCl₂ ".
There are two types of interactions among the atoms and molecules. One are known as intramolecular forces while the other are known as intermolecular forces.
Examples of Intramolecular forces are ionic bonds and covalent bonds e.t.c. while examples of intermolecular forces are hydrogen bond interactions, dipole-dipole interactions e.t.c.
Remember that intramolecular forces ar far more greater in strength than the intermolecular forces. Hence, in given statement the interactions between Caffeine molecules are intermolecular forces while, that between Cu and Cl ions in CuCl₂ are intramolecular forces.
