Answer:
d. Temperature of the liquid
Explanation:
The viscosity of a fluid is determined by temperature, pressure (at very high values), and concentration. The viscosity of a fluid reduces as the temperature rises, resulting in an increase in molecular mobility. When high pressure is applied, it has a minor effect on pressure. The viscosity and concentration have a direct relationship.
Which statement about solubility is true?
A.Solubility is how much solid only will dissolve in liquid only.
B.Solubility is how much solvent will dissolve in solute.
C.Solubility is how much solute will precipitate out of solvent.
D.Solubility is how much solute will dissolve in solvent.
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".
What is solubility?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".

A 5.00 L sample of helium expands to 15.0 L, at which point the pressure is measured to be 0.720 atm. What was the original pressure of the gas
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.
How to calculate pressure?The pressure of a gas can be calculated using the Boyle's law equation as follows:
P1V1 = P2V2
Where;
P1 = initial pressureP2 = final pressureV1 = initial volumeV2 = initial volumeP1 × 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.

A gas occupies 30. L at 2.0 atm pressure and 27°C. Calculate the volume of the gas if
the pressure remains at 2.0 atm, but the temperature is raised to 54°C.
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

Which if the following help a tropical storm become a hurricane? making landfall a cold wind an earthquake warm water
making landfall
a cold wind
an earthquake
warm water
Answer:
a cold wind
Explanation:
It starts as a tropical disturbance. Then, with cyclonic circulation and faster wind speeds, it becomes a tropical depression. If the wind keeps getting faster, it becomes a tropical storm and then a hurricane if winds are more than 74 miles per hour (mph).

more sugar dissolves in hot water than in cold water why?
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.

why can ionic compounds
Conduct electricity ?
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.

How many C8H18 particles would be in 12.6 moles of octane (C8H18)?
Taking into account the definition of Avogadro's number, 7.59×10²⁴ particles of C₈H₁₈ would be in 12.6 moles of octane.
Definition of Avogadro's NumberAvogadro'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.
Amount of C₈H₁₈ particlesThen 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.

two lamps (with a resistance of 10 Ohms each) are connected in a parallel circuit and are supplied with 100- volts of power. which of the following statements are true of the voltage that each lamp receives
a. Each lamp will recieve 50 volts
B. Each lamp will recieve 100 volts
C. The first lamp will recieve more voltage than the second lamp
In the parallel circuit, each lamp will receive 100 volts.
Equivalent resistance of the parallel circuitThe 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
Current in each resistorI = V/R
I = 100/10 = 10 A
Voltage in each resistorV = 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".
