Answer:
52.08grams
Explanation:
Heat of fusion is the energy needed to transform solid water into liquid water. Hess's Law.
The temperature change Liquid water to Solid Ice. 20 degrees C --> 0 degrees C. is 20 degree C.
The heat needed for this is = 4.184 J/(g*C) * (36 grams of water) * 20 degrees C = 3012 joules of energy.
Liquid water to solid water.
Heat of fusion of water is 335j/g = 6.02kJ/mol
The heat needed for this is 6.02 kJ/mol * 2 moles of water = 12.04 kJ = 12040 joules of energy.
Adding the two energies, we have a total energy iof 15052 joules.
15052 joules = H(vap of CCl2F2) * grams of CCl2F2 needed = 289 J/g * x grams 15052 / 289 = 52.08 grams needed.

Benzal .....
Molecular Formula: C11H12O4
Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation.
Answer:
The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.
