(h e l p) a piece of nickel at 25 °c is dropped into a glass of water at 25 °c. which statement is correct? heat will flow from the nickel to the water in the glass. heat will flow from the water in the glass to the nickel. there will be no transfer of heat from the nickel to the water in the glass. the final temperature of water and nickel will be 0 °c.

A, Heat will flow from the nickle to the water in the glass.

the answer is A

Explanation:

because it makes the most sense and i have a feeling in my gut that it is right.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
