What does J stand for in chemistry terms?
'J' is 'Joules' of energy, be it mechanical, heat, electric etc., Named after James Joule a Staffordshire, England , chemist. The basic S.I. units of the J (Joule) are 'kg*m^(2)s^(-2), somtimes written as kg(m/s)^(2) kJ (kilo Joules)= thousands of Joules ( of energy). e.g. 1000 J = 1 kJ

What is the value of delta G at 500 K if delta H 27 kJmol and delta S 0.09 kJ(mol K)?
To calculate the value of ΔG at 500 K, you can use the equation ΔG = ΔH - TΔS. Given ΔH = 27 kJ/mol, ΔS = 0.09 kJ/(mol K), and T = 500 K, plug in the values to find ΔG. ΔG = 27 kJ/mol - (500 K)(0.09 kJ/(mol K)) = 27 kJ/mol - 45 kJ/mol = -18 kJ/mol. Therefore, the value of ΔG at 500 K is -18 kJ/mol.
