The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 1 mc032-1.jpg 106 microliters (mL) in 1 L. What is the volume of this pond in microliters?

Answer: Boiling point

Explanation:

Boiling point is the temperature where the vapor pressure of a liquid equals the pressure of the gas present above it.

The normal boiling point of a liquid is the temperature at which its vapor pressure is equal to one atmosphere.

Boiling point depends on the intermolecular forces present between the molecules. More are the intermolecular forces, lesser will be the vapor pressure and thus more heat will be supplied to make vapor pressure equal to the atmospheric pressure. Thus higher will be the boiling point.

Normal boiling point for water is .

Answer:

• Option B. Calcium chloride (CaCl₂)

Explanation:

The colligative properties depend on the concentration of particles  (molecules or ions) of solute dissolved and not on the identity of the solute.

For your reference the colligative properties are: i) boiling point increase, ii) freezing point depression, iii) vapor pressure lowering, and iv) osmotic pressure.

When the solute is a ionic compound the ionization yields several ions, so for ionic solutes you must predict first the number or ions formed per unit of compound and then predict the effect on the colligative properties: the greater the number of ions per unit of compound the greater the effect on colligative properties.

So, just set the ionization equations for each compound:

• MgSO₄ (aq) → Mg²⁺ (aq) + SO₄²⁻  (aq): 2 ions

• CaCl₂ (aq) → Ca²⁺  (aq) + 2Cl⁻ (aq) : 3 ions

• KI (aq) → K⁺ (aq) + I⁻ (aq): 2 ions

• C₆H₁₂O₆ is a molecular compound, not a ionic one, so it remains s 1 molecule.

Then, since calcium chloride, CaCl₂, produces the greater number of ions it is the solute that productes the greatest effect on colligative properties.

Founder's Education/ Educere Answer

Answer:

The correct option is (4)

Explanation:

Molarity (M) is generally defined as the number of moles of a solute per liter of the solution.

The formula for molarity (from the definition above) is

M = number of moles (n) ÷ volume (in liters or dm³)

The unit for molarity is mol/L or mol/dm³

From the above, it can be deduced that the molarity of an aqueous solution of common salt (NaCl) is the number of moles of NaCl per liter of the salt solution.

Answer: The correct answer is the continuous flow of electric charges in a conductor.

Explanation:

Electric current is defined as the continuous flow of electric charges through a conductor. Direction of the electric current is opposite to the flow of electrons. It is represented by a symbol 'I' and its S.I. unit is Amperes.

Its value depends on the voltage and resistance. The equation representing the relationship between current, voltage and resistance is given by Ohm's Law, which is:

where,

V is the voltage

I is the current

R is the resistance

Hence, the correct answer is the continuous flow of electric charges in a conductor.

Electric current is: C) the continuous flow of electric charges in a conductor.

The movement or flow of electric charges across a conducting media, such as a metal wire, is known as electric current. The mobility of electrons within the conductor is what causes the flow of charges. The flow of electric charges in the majority of conventional electrical circuits is from the negative terminal, where extra electrons build up, to the positive terminal, where there are insufficient electrons.

It's crucial to understand that the passage of atoms in a conductor is not what constitutes electric current. While atoms may vibrate or move slightly within a conductor, the passage of electrons is the main movement in charge of electric current.

Static electricity does not continuously flow through a conductor, and neither does electric current. An imbalance of electric charges on a material's surface is referred to as static electricity, which normally doesn't entail a constant flow or movement of charges.

A staggered passage of charges in a conductor is not how electric current behaves either. Charges flow continuously, uniformly, and orderly through the conductor in a steady electric current.

In conclusion, electricity and electrical circuits are based on the continuous flow of electric charges, typically electrons, in a conductor. Electric current is defined as this flow.

Answer: Option (c) is the correct answer.

Explanation:

Temperature is used as for measuring the average kinetic energy present in a substance or object.

The internal kinetic energy obtained by the molecules of an object is known as thermal energy.

Hence, temperature measures the thermal energy of an object.

Whereas when this thermal energy flows from a hotter object to a cooler object which are placed adjacent to each other then it is known that heat is flowing.

Thus, we can conclude that heat differ from temperature as temperature measures thermal energy, and heat is the flow of thermal energy.

Answer:

C) Temperature measures thermal energy, and heat is the flow of thermal energy.
