a certain mass of gas occupies 2240 volume at a pressure of 760mkhg and temperature of 320k.find it's new volume if the preddure
natita [175]

The new volume : V₂ =  2454.8 L

<h3>Further explanation</h3>

Given

V₁=2240 L

P₁=760 mmHg

T₁=320 K

P₂=700 mmHg

T₂=323 K

Required

Volume V₂

Solution

Combined gas law :

P₁V₁/T₁=P₂V₂/T₂

Input the value :

760 mmHg x 2240 L /320 K = 700 mmHg x V₂/323 K

V₂=(P₁V₁T₂)/P₂T₁

V₂=(760 x 2240 x 323)/(700 x 320)

V₂ = 2454.8 L

Which phrase is an example of what electrostatic forces hold together?
Andreyy89

Answer:

Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together.

Explanation:

The interaction that occurs between atoms that have an electric charge is called electromagnetic force. When the charges are at rest, the interaction between them is called electrostatic force. This force depends on the distance "r" between the atoms.

Depending on the sign of the charges that interact, electrostatic force can be attractive or repulsive. The electrostatic interaction between charges of the same sign is repulsive (two negative charges or two positive charges), while the interaction between charges of the opposite sign (a negative charge and a positive charge) is attractive. In the case of neutral charges against negative or positive charges, no force is generated.

<u><em>Cs+ and Cl− in CsCl is an example of electrostatic forces that hold together. </em></u>In this example you have a positively charged atom (Cs₊) and a negatively charged atom (Cl₋). As they are opposite charges they will attract.
