Answer:

B

Explanation:

As the distance between the planets and the sun increases, the period of revolution increases as well. The period of revolution is how long it takes for a planet to revolve around the sun. So, because the planets farther from the sun have a higher period of revolution in earth years, this also means they have longer actual years, which means the answer is B.

Answer:

the answer is B

Explanation:

look at the table. the closest planet Mercury is 58,000,000 kilometers from the sun, and the furthest Neptune is 4,498,000,000 kilometers from the sun. however, mercury takes 0.24 earth years to make a full rotation, and Neptune takes 165.00 earth years to. so the closer a planet is to the run, the faster its days are

Weak noncovalent interactions:__________ a. do not include ionic interactions b. always involve water. c. can have a large cumul
valentina_108 [34]

Answer:

c. can have a large cumulative effect

Explanation:

Noncovalent interactions between molecules are weaker than covalent interactions. Noncovalent interactions between molecules are of various types which  include van der Waals forces, hydrogen bonding, and electrostatic interactions or ionic bonding.

van der Waals forces  are weak interactions found in all molecules. They include dipole-dipole interactions - formed due to the differences in the electronegativity of atoms - and the London dispersion forces.

Hydrogen Bonds  results when electrons are shared between hydrogen and a strongly electronegative atoms like fluorine, nitrogen, oxygen. The hydrogen acquires a partial positive charge while the electronegative atom acquires a partial negative. This results in attraction between hydrogen and neighboring electronegative molecules.

Ionic bonds result due to the attraction between groups with opposite electrical charges, for example in common salt between sodium and chloride ions.

Even though these noncovalent interactions are weak, cumulatively, they exert strong effect. For example, the high boiling point of water and the crystal structure of ice are due to hydrogen bonding.

White raven [17]

Answer:

The number of neutrons is entirely dependent on the Mass number of the particular atom. The standard mass for potassium is 39.

Potassium is element number 19, so it has 19 protons and 19 electrons in the neutral atom. It has therefore 39-19 = 20 Neutrons.
