Which of the following pairs of elements would form the covalent bond with the largest dipole moment? View Available Hint(s) Whi
LekaFEV [45]

Answer:

In-F bond has the largest dipole moment.

Explanation:

Given the electronegativities:

Ge= 2.01

O= 3.44

H= 2.20

P= 2.19

In= 1.78

F= 3.98

B= 2.04

N= 3.04

The bond between Ge and O has an electronegativity difference:

ED= 3.44 - 2.01= 1.43

The bond between H and P has an electronegativity difference:

ED= 2.20 - 2.19= 0.01

The bond between In and F has an electronegativity difference:

ED= 3.98 - 1.78= 2.20

The bond between B and N has an electronegativity difference:

ED= 3.04 - 2.04= 1.00

As In-F bond has the largest electronegativity difference, this is the covalent bond with the largest dipole moment.

The potential energy diagram for a reaction starts at 180 kJ and ends at 300 kJ. What type of reaction does the diagram best rep
aleksklad [387]

Answer: Endothermic reaction

Explanation:

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and \Delta H for the reaction comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and \Delta H for the reaction comes out to be positive.

As the energy of reactants is 180 kJ and that of products is 300 kJ, the energy of products is greater than that of reactants, which means  the energy has been absorbed and reaction is endothermic.
