3. De Broglie proposed that the wave-particle duality of electrons was analogous to that of
photons of light. Show the two short derivations that relate wavelength and mass.
Then answer the following question: An atom of a particular element is traveling at 1% of
the speed of light. The de Broglie wavelength is found to be 1.11 x 10–14m. Which element
is it?
h = 6.63 x 10-34 J s
c = 3.0 x 108 m/s
N = 6.023 x 1023 atoms/mol

Hi, Please help me this question, especially with last two parts.
Thanks in Advance
In tomatoes, red fruit is dominant to yellow fruit and hairy stems are dominant to hairless (smooth) stems. The two genes controlling these traits are inherited in normal Mendelian fashion and are not linked.
a) Produce a suitable key for this information in terms of the individual alleles of the genes given.
b) What are the possible genotypes of plants showing the following forms:
i) Red fruit and smooth stems :
ii) Yellow fruit and hairy stems :
iii) Red fruit and hairy stems
Write detail please for Part C and D
c) On crossing a plant with red fruit and hairy stem, with one that was yellow fruit and hairy stem, the following progeny were obtained:
30 red, hairy / 11 red, smooth / 29 yellow, hairy / 9 yellow, smooth
d) Give a reasoned explanation along with the use of full genetic diagrams to proof your answer, to explain these results in terms of the simultaneous transmission of characteristics.
Dear Sir/ Madam
Help me with this question please, please write a short explanation also with each
Many thanks in advance.
1) Write a balanced chemical equation to show the dissociation of sodium propanoate (C2H5COONa). Physical states must be included.
