At a constant temperature, a sample of helium at 760 torr in a closed container was compressed from 5.0 L to 3.0 L. What was the
borishaifa [10]

Answer:

The new pressure exerted by the He, is 1266.6 Torr

Explanation:

A typical problem of gases where the volume is increased and the moles and T° keeps on constant. This is an indirect proportion because when the volume of the flask is increased, pressue decreases because molecules  collide to a lesser extent with the walls of the vessel.

P₁ . V₁ = P₂ . V₂

760 Torr . 5L = P₂ . 3L

P₂ = (760 Torr . 5L) / 3L

P₂ = 1266.6 Torr

What happens to the potential energy of the molecules in reaction
OleMash [197]

Decreases

Explanation:

The molecules lose potential energy during chemical reactions.

In a chemical reactions, bonds are broken for new ones to be formed. The process of breaking and forming bonds diminishes the potential energy of a bond.

Potential energy is the energy at rest in a body.

In chemicals, potential energy is constituted by the chemical energy stored within the bonds.

When chemical reactions occur, the energy is released often in the form of heat energy. There is always a decrease in potential energy when chemicals reacts together.
