Some fossils provide clues to the environment and climate of the time the organism lived.
The average kinetic energy of a mole of gas can be determined through the equation KE= 1.5 nRT where R is the gas constant equal to <span>8.314 J/K-mol and T is temperature, The temperature for this problem is 125 Kelvin and n is equal to 1 mole. KE then is equal to 1558.88 Joules.</span>
Answer:
2H2 + O2 -----> 2H2O
Not sure about the second question though.
