Patent - Not sure if this is much of a Chem question dou.
Answer:
a) 6.3 cm
b) 8.0 cm
c) 0.7875
Explanation:
(a) The compound has moved above upto 7.3 cm from the bottom of the paper. Let us assume that line is drawn at 1.0 cm mark as the origin of spot. \
Distance traversed by compound= 7.3 - 1.0 cm = 6.3 cm
(b) Distance traversed by the solvent = 9.0 - 1.0 cm = 8.0 cm
(c) The Rf = Compound Migration distance / Solvent front migration distance
= 6.3/8.0 = 0.7875
Answer:
Explanation:
Noble gases occupy the last group of the periodic table
They have fully filled valence electron shell
What this means is that they have attained stability and thus do not take part in chemical bonding that usually invloves the transfer or sharing of electrons
Thus, noble gases are snobs because they do not partake in chemical bonding with atoms of other elements or atoms of theirselves
Genes are segments of DNA, and DNA is of course a part of fiber from your parents, so when you get that DNA, you usually inherit a few traits or hobbies from them
