Consider the following three statements: (i) for any electro-magnetic radiation, the product of the wavelength and the frequency is a constant. (ii) if a source of light has a wavelength of 3.0 å, its frequency is 1.0*1018 hz. (iii) the speed of ultra-violet light is greater than the speed of microwave radiation. which of these three statements is or are true? (a) only one statement is true. (b) statements (i) and (ii) are true. (c) statements (i) and (iii) are true. (d) statements (ii) and (iii) are true. (e) all three statements are true.

This question is about electrolysis. metal spoons can be coated with silver. this is called electroplating. suggest one reason why spoons are electroplated?

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.
