Answer:

Acid/String Electrolyte

Explanation:

Litmus paper turning red means it is an acidic solution. A pH of more than 7 is Base while pH of less than 7 is an acid. Since the pH is 2, less than 7, it s is an acid. Since it has a high electrical conductivity, it must be a strong Electrolyte.

Explanation:

Gay-Lussac's law states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas when the volume is kept constant. Mathematically, it can be written as: {\displaystyle {\frac {P}{T}}=k}. It is a special case of the ideal gas law.

Answer:

91.4°C

Explanation:

Gay - Lussac Law => T ∝ P => T = kP => k = T/P with volume (V) and mass (n) constant.

For two different Temperature (T)-Pressure (P) conditions

k₁ = k₂ => T₁/P₁ = T₂/P₂ => T₂ = T₁(P₂/P₁)

T₁ = 55°C = (55 + 273)K = 328K      

P₁ = 965 mmHg

T₂ =  ?

P₂ = 850 mmHg

T₂ = T₁(P₂/P₁) = 328K(850 mmHg/965 mmHg) = 364K = (364 - 273)°C = 91.4°C

Answer:

Increasing number of electrons

Explanation:

London dispersion forces are intermolecular forces that occur due to momentary shifts in the electron cloud of atoms or molecules.

London dispersion forces are most commonly observed as the predominant kind of intermolecular forces in non-polar substances.

Generally, it is observed that the strength of these London dispersion forces tends to increase as the number of electrons in the substance increases.

Answer:

A the pressure is changed to 0.8

Explanation:

Boyles gas law

The factor that the chemist changed is so that the new volume is 5.0 L is the final pressure is 0.8 atm, while temperature is kept constant.

Robert Boyle studied the relationship between pressure p and volume V of a fixed amount of gas held at a constant temperature in the mid 1600s.

Boyle discovered that the product of pressure and volume remains nearly constant. For an ideal gas, the product of pressure and volume is a constant.

Thus, the correct option is A, The final pressure is 0.8 atm, while temperature is kept constant.

Answer:

15.9 Liters

Explanation:

according to Boyle's law P1V1 = P2V2

so we just plug in the values the problem gives us and solve for V2

(1.74)(4.21)=(.46)(V2)

V2 = 15.9 Liters

*note - there is a typo in your question when you states P1 = 1 074 atm. I just assumed you meant 1.74, if this is a mistake just replace 1.74 with the real P1 and solve it as shown above

Increasing the surface area between solute and solvent, increases the rate of dissolution.

Rate of any process will gives idea about the speed of the completion of that happening process.

Dissolution is a process in which solute particles gets dissolve in the solvent medium. If we increases the surface area of any one medium of the solution like solute or solvent then the rate of dissolution increases, as it increases the space to get attracted to each other.

Hence, option (d) is correct.

Answer:

[tex]\boxed {\boxed {\sf P_2= 9 \ atm}}[/tex]

Explanation:

Since the temperature is held constant, we only need to focus on the volume and pressure. We will use Boyle's Law, which states the volume of a gas is inversely proportional to the pressure. The formula is:

[tex]P_1V_1=P_2V_2[/tex]

Originally, the gas had a volume of 150 milliliters and a pressure of 3.0 atmospheres. We can substitute these values into the left side of the equation.

[tex]3.0 \ atm * 150 \ mL = P_2V_2[/tex]

The original gas was compressed to a volume of 50 milliliters, but we don't know the volume.

[tex]3.0 \ atm *150 \ mL= P_2 * 50 \ mL[/tex]

Now, we need to solve for the new pressure (P₂). Multiply on the left side first.

[tex]450 \ atm*mL= P_2 * 50 \ mL[/tex]

Since we are solving for the pressure, we need to isolate the variable. It is being multiplied by 50 mL. The inverse of multiplication is division. Divide both sides by 50 mL.

[tex]\frac{450 \ atm*mL}{50 \ mL}= \frac{P_2 * 50 \ mL}{50 \ mL}[/tex]

[tex]\frac{450 \ atm*mL}{50 \ mL}= P_2[/tex]

The units of milliliters will cancel.

[tex]\frac{450 \ atm}{50 }= P_2[/tex]

[tex]9 \ atm =P_2[/tex]

The new pressure is 9 atmospheres.

Answer:

58.86 N

15 kg

Explanation:

w = Weight of an object = 100 N

g = Acceleration due to gravity of Earth = [tex]9.81\ \text{m/s}^2[/tex]

m = Mass of an object

Weight is given by

[tex]w=mg\\\Rightarrow m=\dfrac{w}{g}\\\Rightarrow m=\dfrac{100}{9.81}\\\Rightarrow m=10.19\ \text{kg}[/tex]

Mass of the object is 0.19 kg

g = [tex]2\ \text{m/s}^2[/tex]

m = 4 kg

[tex]w=mg\\\Rightarrow w=4\times 2\\\Rightarrow w=8\ \text{N}[/tex]

Weight of the object is 8 N.

m = 200 g

[tex]w=mg\\\Rightarrow w=0.2\times 9.81\\\Rightarrow w=1.964\ \text{N}[/tex]

Weight of the object is 1.964 N.

Weight is the force the Earth exerts on an object which is on the surface of the Earth.

m = 6kg

[tex]w=mg\\\Rightarrow w=6\times 9.81\\\Rightarrow w=58.86\ \text{N}[/tex]

The force of the object is 58.86 N.

w = 150 N

a = g = [tex]10\ \text{m/s}^2[/tex]

[tex]m=\dfrac{w}{g}\\\Rightarrow m=\dfrac{150}{10}\\\Rightarrow m=15\ \text{kg}[/tex]

Mass of the object is 15 kg.

Answer:

That fresh water hydrates the carbon-based lifeforms on earth. But through evaporation, and transpiration from plants leaf surfaces, it gets back into the atmosphere to feed clouds for the next rainfall. The cycling of liquid water and returning vapor creates our climate and our living environment.

Explanation:

The summary of the water cycle process is given below.

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Water in different phases moves through the atmosphere (transportation). Liquid water flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater).

Groundwater moves into plants (plant uptake) and evaporates from plants into the atmosphere (transpiration). Solid ice and snow can turn directly into gas (sublimation). The opposite can also take place when water vapor becomes solid (deposition).

Therefore, The summary of the water cycle has been explained.
