The entire subsequent are balanced equations. Define the number of atoms of each element in the reactants and in the products. ExplainC5H12 + 8 O2 -> 5 CO2 + 6 H2O
For which of the following transitions would a hydrogen atom absorb a photon with the longest wavelength? a) n=1 to n=2 b)n=2 to n=4 c) n=5 to n=1 d) n=7 to n=6 e) n=5 to n=6
A reaction was conducted in benzene as the solvent. Because the reaction was very exothermic, the mixture was cooled in a salt-ice bath. This was a bad choice. Why?
Nitrogen and oxygen do not react appreciably at room temperature, as illustrated by our atmosphere. But at high temperatures, the reaction below can proceed to a measurable extent.
