<span>Many countries develop GDL systems, that is, a Graduated Driver Licensing system. What this means is that new drivers get special types of driver's permits that don't allow them to drive cars over a certain ammount of horse power or CC, as well as forces them to drive slower than what is actually allowed as they have their own specific restrictions. Over time they get new licenses that allow them to drive like experienced drivers.</span>

Too much exercise or at too intense of a level, can leave you drained, and worse, at risk of injury. Overtraining occurs when a person partakes in too much physical training with too little rest and recovery after hard workouts. Can I get brainliest?
Answer:
DNPH - 2,4-Dinitrophenylhydrazine
Explanation:
This is a chemical compound used for quantitative identification of Ketones and Aldehydes in a sample.Since the urine analysis shows positive results for ketone and aldehydes,this is the test for the this. It is usually marked with yellow/orange precipitate(ppt) (dinitrophenylhydrazone).The latter is formed as a results of condensation reaction.
DNPH is a solid compound whose color changes from red to orange, when used to test for the carbonyl groups.Red when pure.
To conduct the test 1-2drops of the sample is dissolved in 2 ml of ethanol.
This should be added to about 3ml of DNPH,and shake severely for the solute and solvents to mixed up.
Usually, a precipitate should formed afterwards.However,if this did not appear, 15 minutes intervals should be observed for the precipitate( yellow or orange ppt) to appear.
The color of the precipitate depends nature of the carbon molecule or hydrocarbons in the sample. Thus, if the sample is aromatic that is unsaturated hydrocarbon e.g benzene red ppt appears, However, if straight hydrocarbon molecules (aliphatic) Orange ppt appears.
