A gas obeys the equation of state (for 1 mole): P(V-b) = RT where b amounts to 0.5% of the total volume at 27°c and 1 bar. Its molar heat capacity. measured at a pressure of 1 bar is given by Cp(J/mol/K) =29.3+0.0126T(K) What are the changes in molar entropy and molar enthalpy when it is heated from 27°c to 227°c at 1 bar? what are the changes in molar entropy, molar enthalpy and molar Gibbs free energy on compression from 1 bar to 100bar at 227°c?​

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

  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-

its first and third is your answer i did the qustion the fourth isnt right

level 4 to level 2 : ))
