Which change most likely occurs when the kinetic energy of water vapor decreases during condensation?

Answers

Answer:

When the kinetic energy of water vapor decreases during condensation, slowly moving particles near the cool surface condense.

Explanation:

The change of state from a gas to a liquid is condensation. Liquid molecules which have this certain kinetic energy threshold escape from the surface and become vapor. As a result, the remaining liquid molecules now have lower kinetic energy. The temperature of the remaining liquid decreases as evaporation occurs.

The air that surrounded it cooled the cold can or glass. When you're cooling off  .They lose kinetic energy, a gas. The particles move more slowly as they move, the  attractions between them cause the formation of droplets of liquid. Condensed With,  when hot air containing water vapor reaches water, water also forms.  Cold surface touch, such as a glass of ice or soil that has a cold surface  refrigerated throughout the night.

A compound contain only carbon, Hydrogen, Oxygen. Mass percentage of carbon is 52.2%, relative molecular mass of compound is 46, Find how many hydrogen atom present​

Answers

Answer:

Six

Explanation:

Mᵣ                           =  46

Aᵣ(C) = 0.522 × 46 =  24

Difference              =  22

Less 1 O                  = -16

Aᵣ(H)                        =   6

The relative atomic mass of the H atoms is 6.

The molecule contains six hydrogen atoms.

Cations are formed by _____. gaining protons losing protons gaining electrons losing electrons

Answers

Cations are formed by losing electrons in the valence shell of atoms. There are more protons than electron ions making the atom more positive.

An anion has gained electrons and therefore has more electrons than protons. It has a negative charge.


An example if this doesn't make too much sense.

Charged Atoms: If electrons are removed from an atom, that atom becomes positively charged because it has more positive charge carriers (protons) than negative charge carriers (electrons)

These types of charged atoms are called positive ions or, cations. DEPENDING ON THE CIRCUMSTANCES, the removed electrons can remain free or they may attach themselves to another atom that can accept extra electrons. If this occurs, a negatively charged ion, or anion, is created.
