indicate whether the entropy of the system increases or decreases. Mixing 10 mL of 90.0 °C water with 10 mL of 10 °C water. The
Ivanshal [37]

Answer:

When the water is mixed with water at lower temperature the effective temperature of the system (i.e the water at lower temperature) will increase, thereby increasing it's entropy

Explanation:

The answer that "the entropy will is increases" is correct as:

The water at 90° C i.e at higher temperature is mixed with the water at 10° C i.e the water at the lower temperature.

The water at lower temperature will have molecules with lower energy while the water with higher temperature will have molecules undergoing high thermal collisions. Thereby, when the water is mixed with water at lower temperature the effective temperature of the system (i.e the water at lower temperature) will increase, thereby increasing it's entropy.

Therefore, the answer is correct with respect to the water at lower temperature.

Meanwhile, for the water at higher temperature , the temperature of the system will decrease. Thus, the entropy of the water at higher level will decrease.

Sodium explodes when it contacts water. If I have a compound that contains sodium, will it explode if it is exposed to water?
Vaselesa [24]

Answer:

Option D = No, when elements combine to form a new material, they have properties unique to the new materials.

Explanation:

When sodium contact with water it loses its one electron and thus gain positive charge. When there are more sodium atoms present and many atoms do this thus more positive ions are produced and these positive ions repeal each other at high speed and explosion occur.

But when it form compound with other material, it will not showed this behavior.

Example:

Consider the sodium chloride, when it dissolve in water sodium not showed explosion. In sodium chloride sodium already gives its electron to the chlorine and have stable electronic configuration. The sodium present in cationic form. When it dissolve, partial positive charge of water surrounds the Cl⁻ and partial negative charge of water surrounds the Na⁺ ion, ans sodium chloride gets dissolve into water without explosion.

Draw corresponding structure of 1-cyclophentylhexane.​
I am Lyosha [343]

Answer:

Hexane is a 6-carbon hydrocarbon.

Cyclopentyl is a 5-carbon, hydrocarbon ring.

The 1- indicates that the cyclopentyl is attached to the first carbon in hexane.

Two ways of drawing the structure of 1-cyclopentylhexane are below:

What is the relationship between pH, acidity, and H1 concentration ?
irina [24]
PH = - log [concentration of H+]    

pH = - log [H+]

pH IS A MEAUSE OF ACIDITY AND BASIDITY OF A SUBSTANCE....

AS ACIDITY OF A SUBSTANCE DEPENDS ON THE IONISATION OF H+
THEREFORE IT IS A MEAUSE...

THE LOWER THE PH VALUE, THE MORE ACIDIC IS THE SUBSTANCE
