Answer:
Sulfur dioxide relased by the industry=
25%
Explanation:
The amount of sulfur dioxide relased by the industry can be calculated by looking at the values of the other; transport and electricity generation. Since electricity generated sulfur dioxide is 69% + 6% of transport that equals 75%. Pie diagrams always equal a total of 100%.
so simply you minus 75 from 100: 100-75=25%.
Answer: 0.72 AND 0.5 RESPECTIVELY/.
Explanation:
The Rf value is defined as the ratio of the distance moved by the solute (i.e. the dye or pigment under observation) and the distance moved by the the solvent ie the migration of the solvent along the paper, where both distances are measured from point where the sample is first spotted on the paper.
Rf value= (migration distance of substance)/(migration distance of solvent front)
or
Rf value=Distance from Baseline travelled by Solute
/Distance from Baseline travelled by Solvent (Solvent Front)
For Arginine Rf = (4.9 cm)/(6.8 cm) = 0.72
For glycine Rf = (3.4 cm)/(6.8 cm) = 0.5
