Which of the following compounds is least solublein water?
(1) copper (II) chloride
(2) aluminum acetate
(3) iron (III) hydroxide
(4) potassium sulfate

Answers

Answer 1

Answer:

Iron (III) hydroxide is the least soluble compound as it has the lowest Ksp value.

What is solubility of a solute?

The solubility is the amount of solute that can dissolve in a given volume of solvent at a particular temperature.

The solubility of substances can be compared using their their solubility products constant (Ksp) values.

Iron (III) hydroxide has the lowest Ksp value.

Therefore, Iron (III) hydroxide is the least soluble compound.

A beaker with water and the surrounding air are all at 24°C. After ice cubes are placed in the water, heat is transferred from:(1) the ice cubes to the air
(2) the beaker to the air
(3) the water to the ice cubes
(4) the water to the beaker

Answers

The answer is (3) the water to ice cubes.

As the ice cubes should be at a temperature of about 0 degree ( freezing point) , at the same time the temperature of water is 24 degree. Thus, heat is transferred from water to ice cubes.

(3) the water to the ice cubes
This is so because the ice cubes are colder compared to their surrounding objects.
They absorb the heat from the water, cooling it, therefore vanishing(melting).

Another name for the activated complex is _____.a. energy barrier
b. transition state
c. rate limiter
d. collision group

Answers

Answer:

Another name for the activated complex is Transition State.

Explanation:

According to Collision Theory for a chemical reaction to occur the reactants must collide with proper orientation and required energy. In this way the old bonds are broken and new bonds are formed. The mid point of highest energy at which both bond formation and breakage is taking place is called activation complex, a complex in between reactant and product.

The energy of this complex is the minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.

This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger. Hence, the activated complex is in transition between reactants and products.

A student blows up a ballon and then places it in a very cold freezer the ballon shrunk after hours why!?

Answers

Temperature is directly related to the speed of the molecules such that as the temperature decreases, so does the speed of the molecules. When the balloon was placed in the freezer, the temperature plummeted and so the molecules moved less. Due to this lack of movement, less space was used by the balloon so it shrunk.
