Samples of three gases, CH4 (g), Ar (g) and H2 (g) at STP are placed in three 1.00 L containers. The same amount of heat is added to all three samples.

Match the final temperatures of the samples with the proper gas.
294.56K
288.52K
285.60K

Match the molar heat capacities with the proper gas.
20.8 J/mol K
35.6 J/mol K
28.9 J/mol K

Based on this information, determine how much heat was added to the systems. q = J

  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-

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
