Explanation / Answer

AS PER CHEGG POLICY, PROCEEDING TO ANSWER ONLY THE FIRST 4 QUESTIONS/SUBPARTS, THAT IS, QUESTIONS 30 TO 33:

ANSWER 30
The most reactive element out of the given list is:
c. Potassium - as per the order of reactivity, a series that describes their inter-relationship. It is expressed as the affinity for forming a compound

ANSWER 31
Most organic [compounds] molecules are made up of carbon and hydrogen
a. True - Organic compounds are based of Carbon structure wherein most of the times the remaining bonds are filled up with Hydrogen

ANSWER 32
The term denaturation means:
d. Breaking of hydrogen bonds in the proteins - as denaturation is the process by which the shape determining levels of protein structure are lost and spacial arrangement is altered.

ANSWER 33
The isomer of glucose is:
d. Fructose - They have the same structure while one is the aldose version, the other is the ketose version
