How is the Law of Conservation of Mass, Matter, Phases of Matter, and Physical/Chemical Changes similar/connected to one another
kogti [31]

Answer:

Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don't move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid.

What does Gibbs free energy predict?
kicyunya [14]

Answer:

It predicts whether or not a reaction will be spontaneous.

Explanation:

The equation;

∆G= ∆H - T∆S enables us to obtain the Gibbs free energy of a chemical process.

The Gibbs free energy value tells us whether a chemical process will be spontaneous or not.

When;

∆G>0 the reaction is not spontaneous

∆G=0 the reaction is at equilibrium

∆G<0 the reaction is spontaneous

What would be the new volume if the pressure on 600 L is increased from 90.0 kPa to 150 kPa?
Liono4ka [1.6K]

Answer:

new Volume of gas=360L

Explanation:

Assume that given gas follow the ideality nature of gas

Assuming that temperature is constant;

P1 and V1 are the initial parameter of gas

and p2 and V2 are the parameter after increasing the pressure

according to boyle 's law pressure is inversly proportional to the volume at constant temperature.

P_1V_1=P_2V_2

given value of volume and gas

P1=90kPa

V1=600L

P2=150kPa

V2=?

After putting all values we get;

V2=360L

new Volume of gas=360L
