Bond Breaking and Bond Making

What is bond energy?

• The amount of energy released when a chemical bond is formed between two atoms in a molecule.

• The amount of energy required to form a chemical bond between two atoms in a molecule.

• The amount of energy required to break a chemical bond between two molecules.

• The amount of energy required to break a chemical bond between two atoms in a molecule.

Define bond breaking.

• Process of breaking the chemical bonds between atoms in a molecule

• Process of forming chemical bonds between atoms in a molecule

• Process of strengthening the chemical bonds between atoms in a molecule

• Process of rearranging the chemical bonds between atoms in a molecule

Define bond making.

• Process of converting chemical elements

• Process of forming chemical bonds

• Process of separating chemical compounds

• Process of breaking chemical bonds

What are energy changes in the context of bond breaking and bond making?

• Energy changes in bond breaking and bond making refer to the energy required to form bonds but do not involve any energy release when existing bonds are broken.

• Energy changes in bond breaking and bond making refer to the energy required to form bonds and the energy released when existing bonds are broken.

• Energy changes in bond breaking and bond making refer to the energy required to break bonds and the energy released when new bonds are formed.

• Energy changes in bond breaking and bond making refer to the energy released when existing bonds are broken but do not involve any energy requirement to form new bonds.

How is bond energy related to bond breaking and bond making?

Explain the concept of bond energy.

• Bond energy is the energy required to form a chemical bond between two atoms.

• Bond energy is the amount of energy released when a chemical bond is formed.

• Bond energy is the energy released when a chemical bond is broken and neutral isolated atoms are formed.

• Bond energy is the amount of energy required to break a chemical bond and form neutral isolated atoms.

What happens to energy when a bond is broken?

• Energy is released

• Energy remains constant

• Energy is absorbed

• Energy is destroyed

What happens to energy when a bond is formed?

• doubled

• released

• absorbed

• destroyed

What factors affect bond energy?

• bond length, bond strength, and electronegative atoms

• atomic number, atomic mass, and atomic radius

• temperature, pressure, and concentration

• pH, solubility, and viscosity

How can bond energy be calculated?

• By analyzing the color of a molecule.

• By measuring the distance between atoms in a molecule.

• By counting the number of bonds in a molecule.

• By measuring the energy required to break a bond in a molecule.
