Relatively few hydrogen atoms
Answer: 15.8 g of 
will be required to produce 1.60 grams of 
Explanation:
To calculate the moles :
According to stoichiometry :
As 1 mole of is given by = 2 moles of
Thus 0.05 moles of is given by =
of
Mass of 
Thus 15.8 g of will be required to produce 1.60 grams of
Jacques Cartier is the first explorer to reach North America
Answer:It would depend on the eluent solvent what we use ,If we would use a polar solvent than B will be appear first followed by c and then A on the chromatography strip.
If we use non-polar eluent solvent than A will be separated first followed by C and thenB on the chromatography strip.
Explanation:
Separation using paper chromatography is dependent upon the polarity of various pigments .
A polar pigment would move ahead in case of polar solvent used and a non-polar pigment would move ahead when we use a non-polar solvent.
So separation would occur in order of polarity of various pigments in a given solvent.
The amount of distance travelled by each component (or pigment or spot) can be calculated using the formula for retention factor:
Rf= Distance travelled by pigment spot or solute/Distance travelled by eluent solvent
Rf= Retention factor
Retention factor is basically the ratio of distance tarvelled by the pigment or spot to the ratio of distance travelled by the solvent.
The process of domestication is called artificial selection.Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different genetically determined traits in order to increase the frequency of desirable traits in the population.
