CH4+2O2–> CO2+2H2O
-count the number of atoms of each element on each side of the reaction arrow, there is 1 carbon,4 hydrogen, and 2 oxygen on the reactant side and 1 carbon, 2 hydrogen, and 3 oxygen on the product side.Then add coefficients so the number of atoms of each element is the same on both sides of the equation
<u><em>THEY ARE NOT AFFECTED BY EARTH`S ATMOSPHERE</em></u>
A.) Heat, light, or sound.
The answer would be: C. 160.3 J/mol*K
To solve this question, you need to know the equation for Gibbs free energy formula. Entropy is expressed as delta S. The temperature would be expressed as T. Don't forget that temperature use Kelvin as unit, not Celsius
The formula would be:
G= H- T*S
130.5 kJ/mol= 178.3kJ/mol - (25+273.15K)*S
(298.15K)*S=178.3kJ/mol - 130.5 kJ/mol
S= (47.8kJ/mol)/ 298.15K=
S= 0.1603 kJ/mol*K= 160.3 J/mol*K ------> 1kJ= 1000J
