Which statement is true regarding the function of a catalyst in a chemical reaction?.
guajiro [1.7K]

Answer:

You didn't give any options/statements, so I'm just going to give you context on what catalysts does. Catalysts decrease the activation energy needed, allowing more particles for successful reactions.

I know my colleague tried doing an experiment by using hydrogen peroxide as a catalyst and seeing how rates of reactions were affected. It ended up with a stain on our chemistry lab and him re-doing his entire lab.

Use Lewis theory to draw the structure of the compound containing 1 carbon and 4 chlorine atoms. What would you find surrounding
Nikolay [14]

Answer :  The correct option is, (B) no double bonds.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

As we are given that the structure of the compound containing 1 carbon and 4 chlorine atoms.

Thus, the molecule is, CCl_4

As we know that carbon has '4' valence electrons and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in CCl_4 = 4 + 4(7) = 32

According to Lewis-dot structure, there are 8 number of bonding electrons and 24 number of non-bonding electrons.

From the Lewis-dot structure we conclude that there are 4 single bonds are surrounding the central atom of this ion there is no double or triple bonds are present.

Hence, the correct option is, (B) no double bonds.
