what is the molar mass of copper sulfate?

Answer:

The process in which we breathe out carbon dioxide and breathe in oxygen.

Explanation:

Explanation:

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Answer:

C. Solubility is how much solute will dissolve in solvent.

Explanation:

Solvent dissolves solutes, not the other way around, and solids aren't the only things that have solubility, I don't see how precipitation has anything to do with this, so answer C. is the correct answer. Also, I took the test and got the answer right.

The statement that is true about solubility is "Solubility is how much solute will dissolve in solvent".

Solubility is the amount of solute that can be dissolved in a solvent. Generally, the solubility of most solutes increases with an increase in the temperature of the solvent.

The property that can help sugar molecules or salt crystals to dissolve is known as solubility.

Factors that affect solubility include:

Concentration of the solute

Temperature

Pressure

Polarity of the solute and the solvent

Given options are-

Solubility is how much solid only will dissolve in liquid only.

Solubility is how much solvent will dissolve in solute.

Solubility is how much solute will precipitate out of solvent.

Solubility is how much solute will dissolve in solvent.

Therefore, The statement that is true about solubility is "Solubility is how much solute will dissolve in solvent".

In the parallel circuit, each lamp will receive 100 volts.

The equivalent resistance of the parallel circuit is the inverse sum of the resistance of the two resistors in the circuit. This is as a result of different current flowing in each resistor parallel circuit arrangement.

The equivalent resistance is calculated as follows;

1/R = 1/10 + 1/10

1/R = 2/10

R = 10/2

R = 5 ohms

I = V/R

I = 100/10 = 10 A

V = IR

V = 10 X 10 = 100 V

Generally, for a circuit in parallel connection, same voltage will flow in each resistor of the circuit while different current will flow in the resistors.

Thus, the correct statement is, "Each lamp will receive 100 volts".

Answer:

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

The original pressure of a gas that has 5.00 L of its sample expanded to 15.0 L, at which point the pressure is measured to be 0.720 atm is 2.16atm.

The pressure of a gas can be calculated using the Boyle's law equation as follows:

P1V1 = P2V2

Where;

P1 × 5 = 15 × 0.720

5P1 = 10.8

P1 = 10.8 ÷ 5

P1 = 2.16atm

Therefore, the original pressure of a gas that has 5.00 L of its sample expanded to 15.0 L, at which point the pressure is measured to be 0.720 atm is 2.16atm.

Resonance and transmission​ are the two aspects of sound waves that the student observe.

Resonance is defined as when one object vibrating at a specific natural frequency and compels the second object into vibrational motion.

We know that sound waves required medium and transmit from one place to other by transferring the sound energy to its neighbouring particles so we can conclude that Resonance and transmission​ are the two aspects of sound waves that the student observe.

Answer:

V2 = 33L

Explanation:

KNOW THAT:

V1 = 30L

P1 = 2.0atm

T1 = 27 + 273.15 = 300.15k (it's help to be in Kelvin)

P2 = 2.0 atm

T2 = 54 = 273.15 = 327.15

V2 = ?

We have an equation: P1V1/T1 = P2V2/T2

Multiply both side for T2 to remove it, divided both side for P2 to remove it. So we can left with V2, and that is what we want to find.

T2P1V1/T1P1 =>> V2= 33L

Taking into account the definition of Avogadro's number, 7.59×10²⁴ particles of C₈H₁₈ would be in 12.6 moles of octane.

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: If by definition of Avogadro's number 1 mole of C₈H₁₈ contains 6.023×10²³ particles, 12.6 moles of the compound contains how many particles?

amount of particles of C₈H₁₈= (6.023×10²³ particles × 12.6 mole)÷ 1 mole

amount of particles of C₈H₁₈= 7.59×10²⁴ particles

Finally, 7.59×10²⁴ particles of C₈H₁₈ would be in 12.6 moles of octane.
