Consider the distinction between evolution and natural selection.
a) Under what circumstances can evolution occur in the absence of natural selection? Give two different examples, invoking different evolutionary forces in each.
b) In what circumstances can natural selection occur and yet not result in evolution? Give two different examples.
Determine the maximum number of moles of SO2 produced from 12 moles of H2S and 4.0 moles of O2
write the skeleton equation representing the heating of magnesium carbonate to produce solid mangnesium oxide and carbon dioxide gas.
The 13C nucleus is a spin 1/2 particle, which means it can orient in two directions in a magnetic field (with the field and against it). The difference in energy between the two orientations is given by:
