Answer: A solute dissolves because its particles interact with the particles of a solvent. Anything that allows more solvent to touch more solute will cause a solute to dissolve more quickly. Small pieces of a substance dissolve faster than large pieces.
Answer: <span>Ethanoic acid (CH3COOH)
Reason:
Chemical property of substance depends upon the functional group associated with the system. Compound with same functional group will have similar chemical properties.
In present case, </span>propanoic acid has an acidic functional group (-COOH). Also, ethanoic acid has an acidic functional group (-COOH).
On the other hand, propanal and1-propanol have aldehydic (-CHO) and alcoholic (-OH) functional group. <span>Propane is a pure alkane and will have minimum chemical reactivity.
Due to this, propanoic acid will have chemical properties similar to ethanoic acid. </span>

<span>It’s the gas physical state that shows the greatest
change in volume and changes in temperature or pressure. Because gas is the
matter that is composed of loose particles but can be compressed. Since gas contains
loose molecules, the molecules can freely move in a certain object, so when
physical change happens, it exhibit greatest change. Gas also follow the shape
of its container and can expand in order to fill its container. It has no
definite volume or shape. </span>
Answer:
The minimum amount of energy needed the the cell to perform various cellular,biochemical and physiological activities is known is Gibbs free energy.
Explanation:
The change in gibbs free energy of is very much important to determine whether a given reaction is spontaneous,non spontaneous or equilibrium.
1 If gibbs free energy change of a reaction is negative then the reaction is spontaneous.
2 If the free energy change is 0 then the reaction is in equilibrium stage.
3 If free energy change is positive then the reaction is non spontaneous.
