Answer : Option 2) providing an alternate reaction pathway that has a lower activation energy


Explanation : When a catalyst is added to a chemical reaction it increases the rate of reaction by lowering the energy of activation. It provides an alternate pathway for a reaction to proceed with a lower Ea energy. Usually a catalyst never gets consumed in the reaction process. It will appear in the reaction mechanism steps but not in the overall reaction like reactants and products.

The answer is (2) providing an alternate reaction pathway that has a lower activation energy. The lower activation energy will lead to the increase of rate of the reaction.

Masja [62]

Answer:

The atomic mass of the boron atom would be <em>10.135</em>

Explanation:

This is generally known as relative atomic mass.

Relative atomic mass or atomic weight is a physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass of 1/12 of the mass of a carbon-12 atom. Since both quantities in the ratio are masses, the resulting value is dimensionless; hence the value is said to be relative and does not have a unit.

<em>Note that the relative atomic mass of atoms is not always a whole number because of it being isotopic in nature.</em>

  • <em>Divide each abundance by 100 then multiply by atomic mass</em>
  • <em>Do that for each isotope, then add the two result. Thus</em>

Relative atomic mass of Boron = (18.5/100 x 11) + (81/100 x 10)

                                                 = 2.035 + 8.1

                                                 = 10.135
