Answer:HNO3 + NaOH → H2O + NaNO3
Explanation:
A straight chain hydrocarbon with the formula C5 H10: has a double C-C bond
Answer:
Different compounds are formed.
Explanation:
Due to this switching of chemicals, the result of both beakers will be different because the chemicals react with the different solution in the beaker. The composition of both chemicals are different from one another which produces different compounds or products when they are mixed with the solution so we can say that this switching of chemicals will definitely affect the results of the experiment. The student will observe the formation of different compounds and different colour of the solution.
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.
