Answer: Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms.

Soil structure affects plant growth in many, often surprising, ways. The most obvious effects are on root growth, which is strongly inhibited by hard soil, and which in turn influences the ability of the root system to extract adequate water and nutrients from the soil.

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.

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:

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.

I believe that it is a prediction.

Explanation:

Because you can't kick the ball and say it will go into the goal. Of course if it is right in front of the goal and you kick it will go in but in both cases if you kick it too hard it will go in and then bounce off the net and roll back out of the goal. So in my opinion it is a prediction.

Answer:

Percentage yield = 92.86%

Explanation:

We are given;

Actual yield = 3.9 grams

Theoretical yield = 4.2 grams

Formula for percent yield is;

% yield = (actual yield/theoretical yield) × 100%

Thus;

% yield = (3.9/4.2) × 100%

% yield = 92.86%

Answer:

I believe that it would be faster but the reaction would not happen immediately. It would take a long time for the effect to start kicking in but it will definitely speed up the process of CO2 being released into our atmosphere.

Explanation:

If CO₂ is being produced in the solution at a faster rate than H₂CO₃, then the rate of the forward reaction is faster.

Rate of any reaction tells about the duration of the completion of reaction to produce products.

Given chemical reaction is written as:

H₂CO₃ ⇄ CO₂ + H₂O

In the question it is given that CO₂ is produced at the faster rate, and it is the product of the forward reaction. So, we conclude that rate of forward reaction is faster.

Hence, the rate of forward reaction is faster.

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:

Explanation:

To find the pH we must first find the pOH

The pOH can be found by using the formula

pOH = - log [ {OH}^{-} ]

We have

[tex]pOH = - log(8.2 \times {10}^{ - 8} ) \\ = 7.086186...[/tex]

pOH = 7.09

Next we use the equation

pH = 14 - pOH

We have

pH = 14 - 7.09

We have the final answer as

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

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.
