Choose the statements that are true about bond strength.

a. bonds formed between two atoms with a large difference in electronegativity tend to be strong.
b. strong bonds are easy to break.
c. stronger bonds release less energy when broken than weak bonds do.
d. longer bonds are weaker.

A. Bonds formed between two atoms with a large difference in electronegativity tend to be strong.

Explanation:

Bonds formed between the atoms is basically the electromagnetic force between the molecules due to which they are bonded together. If the electromagnetic force between the molecules is strong then it means the bond between the molecules or atoms are much stronger.

Strong bonds need more energy to break it and since it requires more energy to break the strong bonds so here the energy released will be more in strong bonds and it release less energy in weak bonds.

So here correct answer for bond between the atoms is

A. Bonds formed between two atoms with a large difference in electronegativity tend to be strong.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
