The stronger intermolecular force has been found in glycerol with high viscosity as it has a larger molar mass. Thus, option A is correct.
The viscosity has been defined as the resistance of the fluid to the deformation. The viscosity has been dependent on the molar mass and intermolecular force in the compounds.
The stronger intermolecular force and molar mass tend to have more resistance to the deformation and thus have more viscosity.
The intermolecular force present in glycerol and water is hydrogen bonding. The molar mass of glycerol has been higher than water, this tends to have more resistance and viscosity.
Thus, glycerol has high viscosity as it has a larger molar mass. Thus, option A is correct.

Answer:
The minimum resistance is 25 ohms.
Explanation:
Resistance of each resistor is 100 ohms. When resistors are connected in parallel, the equivalent resistance is lowest. For parallel combination, the equivalent resistance is given by :
Here, all resistors are 100 ohms. So,
So, the minimum resistance is 25 ohms.
Answer:
3 moles of hydrogen, , are needed to react completely with 1 moles of nitrogen,
Explanation:
Let us consider the Reaction of Nitrogen and hydrogen
Two nitrogen atom reacts with 3 hydrogen atom to form ammonia. So it is clear from the chemical equation that 3 moles of hydrogen atom is essential to react completely with nitrogen.
Also when we see the atomic structure of hydrogen and nitrogen ,Hydrogen has only one electron its shell and nitrogen has 5 electron in its valency shell. so for an Nitrogen to have a completely filled shell, it needs 3 more electrons .Thus is need 3 hydrogen atom
