Answer: Reaction (1) , (3) and (4) are accompanied by an increase in entropy.
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
(1) 
3 moles of reactant are changing to 1 mole of product , thus the randomness is increasing. Thus the entropy also increases.
2) 
1 mole of Liquid reactant is changing to 1 mole of solid product , thus the randomness is decreasing. Thus the entropy also decreases.
3) 
1 mole of Liquid reactant is changing to 1 mole of gaseous product , thus the randomness is increasing. Thus the entropy also increases.
4) 
1 mole of Liquid reactant is changing to half mole of gaseous product and 1 mole of liquid product, thus the randomness is increasing. Thus the entropy also increases.

See explanation
Explanation:
A substance is only soluble in water if it is composed of ions or polar groups which are capable of interaction with water.
Salt is composed of ions which are easily solvated by the dipoles of water molecule. Sucrose is composed of polar groups capable of interaction with water. This accounts for the solubility of sucrose (sugar) in water. Sugar is a covalent molecule but is composed of polar groups while salt is composed of ionic bonds.
Hence salt and sugar are both soluble in water for the reasons described above.

Answer:
It measures the capacity to do work.
Explanation:
Recall that 1 gallon = 3.785 L, and 1 L = 1000 mL, so to calculate volume in millilitres, multiply by 3.785 and 1000, resulting in 3785 mL. Next, multiply volume by density to calculate mass (Density = Mass/Volume), so 3785 mL * 1.000 g / mL = 3785 g of water.
