4. Which of the methods below could be used to crack a long-chain hydrocarbon?
A Mix the hydrocarbon with water and add
a cold platinum catalyst.
B Mix the hydrocarbon vapour with steam
and heat to a very high temperature.

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
