A rectangular block of a certain metal has a length of 2.75 decimeters and a width of 4.65 decimeters. It has a mass of 104.499 kilograms. As it cools from 212 degrees F to 32 degrees F it loses 1,306.243 kilocalories. What is the height of the
block in inches?
a. 2.66 inches
b. 11.89 inches
c. 16.71 inches
d. 29.087 inches
e. 7.087 inches
f. 21.33 inches

mg3n2 is known as magnesium nitride

explanation:

i don't think ke is an compound

the product of the pressure and volume is also constant

  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-

points
