The decomposition of calcium carbonate, CaCO3(s) > CaO(s)+CO2(g), has the following values for free energy and enthalpy at 25.0°C /\G=130.5 kJ/mol
/\H=178.3 kJ/mol

What is the entropy of the reaction?
Use /\G=/\H-T/\S

A. -160.3J/(mol. K)
B. -47.8J/(mol. k)
C. 160.3 J/(mol. k
D. 1912 j/(mol. k

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

can you list the answers so i can answer

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock
