3. Find the entropy change of the system and of the surroundings if 3.000 mol of water freezes reversibly at 1.000 atm. The freezing temperature is 0.00°C at this pressure, ,
and the specific enthalpy change of fusion is equal to 79.7 cal g'at this temperature.​

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.

Acovalent bond is formed between the two hydrogen bonds

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
