explain how soil can affect the composition of the solution that move through it
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.

Na2O H2 --> 2Na H2O A student performed the above reaction in the lab, and obtained an actual yield of 3.9 grams of H2O. He calculated a theoretical value of 4.2 grams of H2O. Calculate the percent yield of the reaction.
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%

A gas occupies 4.21 Iiters at a pressure 1 074 atm. What will its volume be if the pressure is decreased to 0.46 atm?
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 Select one: a. has no effect on the rate of dissolution. b. decreases the rate of dissolution. c. can increase, decrease, or have no effect on the rate of dissolution. d. increases the rate of dissolution.
Increasing the surface area between solute and solvent, increases the rate of dissolution.
What is rate?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.

8. If 400 mL of gas has a temperature of 75°C, then what would be the new volume if the temperature increased to 95°C?
We are given:
V₁ = 400 mL T₁ = 75°c = (273+75)K = 348K
V₂ = x mL T₂ = 95°c = (273+95)K = 368K
Deriving Boyle's Law:
here, we can see that the volume and temperature are the only variables
from the ideal gas equation:
PV = nRT
T /V = P / nR
because P, n and R are constants, P/nR is a constant value
T / V = constant
which means that the initial and final ratio of P and T will be constant, hence:
T₁ / V₁ = T₂ / V₂, this is also known as the Charles' law. what I did above was it's derivation
Finding final volume:
plugging the given values:
348/400 = 368 / x
x = 368*400 / 348
x = 422.9 mL
What is the role of the producer in any food chain?
Question 1 options:
Producers turn light energy into food energy
Producers make the food that consumers eat
Without producers, consumers would starve
All of these answers are correct
Answer:
All of these answers are correct.
Explanation:
They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.

written!
If he kicks the ball, then it will go into the goal.
Answer:
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.

What is the new pressure of 150 mL of a gas that is compressed to 50 mL when the original pressure was 3.0 ATM and the temperature is held constant
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.
how does gas create pressure?
a. the force of a collision between two gas molecules with the same amount of kinetic energy creates pressure
b. the force of a collision of a gas molecule against the walls of its container create pressure
c. the force of a collision between two gas molecules with different temperatures creates pressure
d. the force of a collision of a gas molecule against the air in a container creates pressure

1.00 mole of an ideal gas occupies a volume of 22.4 L at 0 C and 760 mmHg (STP). It is cooled to -41 C while the pressure is increased to 805 mmHg. What is the new volume of the gas in liters?
Answer:
[tex]V_2=18.0L[/tex]
Explanation:
Hello there!
In this case, according to the given information, we infer that we need the combined gas law in order to solve this problem:
[tex]\frac{P_2V_2}{T_2}} =\frac{P_1V_1}{T_1}}[/tex]
Thus, by suing the temperatures in Kelvins, we can solve for the final volume as shown below:
[tex]V_2 =\frac{P_1V_1T_2}{T_1P_2}}\\\\V_2 =\frac{(760mmHg)(22.4L)(232K)}{(273K)(805mmHg)} \\\\V_2=18.0L[/tex]
