Of these four liquids, which has the lowest viscosity? options: A. Pancake syrup at room temperature B. Motor oil that is in the refrigerator C. Liquid mercury at room temperature D. A glass of lemonade at room temperature

Option C, .Liquid mercury at room temperature

Explanation:

The viscosity of liquid mercury at room temperature is 1.526 cP. While the visocsity of lemonade at room temperature ranges between 15.10 to 17.44 cP. Viscosity of Motor oil kept in the refrigerator is equal to 1328.0 cP. And Viscosity of Pancake syrup at room temperature  is 5,000 cp. Hence, out of all the four liquids, mercury has the lowest viscosity

Hence, option C is correct

d.) circle motion requires a force to give it a centripetal acceleration.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
