The activation energy of an endothermic reaction

Chemistry
1 answer:
yarga [219]4 years ago
7 0

Answer:

The activation energy of an endothermic reaction

A) must be greater than the required △H

Explanation:

endothermic reaction : Are those which absorbs heat from the surrounding

.<em>This energy provide activation energy for the reaction to occur</em>.

So activation energy becomes more than enthalpy.

Which change most likely occurs when the kinetic energy of water vapor decreases during condensation?
mylen [45]

Answer:

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

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.

What happens when chlorine forms an ion?
zmey [24]

The chlorine usually forms a Chloride ion.

The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

What do you mean by Chlorine forming an ion?

Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.

The chloride ion is the anion  Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.
