The rate of the reaction increases when a catalyst has been added to the reaction mixture by e) providing a new mechanism for the reaction to procced by
Catalyst, in chemistry, a substance that speeds up a reaction without itself being consumed. Enzymes are natural catalysts responsible for many important biochemical reactions.
Most solid catalysts are oxides, sulfides, halides of metals or metallic elements, and metalloid elements boron, aluminum and silicon. Gas and liquid catalysts are usually used in pure form or in combination with suitable carriers or solvents. Solid catalysts are usually dispersed in another material known as a catalyst support.

Answer:
Lithium loses one electron to fluorine and forms ionic bond, having formula 
.
Explanation:
Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is ![[He]2s^1](https://tex.z-dn.net/?f=%5BHe%5D2s%5E1)
.
Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is ![[He]2s^22p^5](https://tex.z-dn.net/?f=%5BHe%5D2s%5E22p%5E5)
.
<u>Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged.</u> This is done in order that the octet of the atoms are complete. <u>These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.</u>
Thus, the formula of calcium chloride is .
Answer:
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.Explanation: hope this helps god bless you
