Answer:

A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south of the equator.

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.

Yes, potassium metal can be used to react with an acid to prepare a soluble salt.

Acids react with metals to yield the corresponding metal salt and hydrogen gas.

One of the properties of metals is their ability to react with dilute acids to yield  a soluble salt and hydrogen gas. This is a common reaction for all metals that are above hydrogen in the activity series.

Potassium can react with a hypothetical acid HB as follows;

2K(s) + 2HB(aq) ------> 2KB(aq) + H2(g)

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:

R = 40 ohms

Explanation:

Given that,

The voltage of outlet, V = 120 V

Current flowing through the device, I = 3 A

We need to find the Resistance rating of  the power cord. Let the resistance is R. We know that,

Ohm's law, V = IR

Put all the values,

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{120}{3}\\\\R=40\ \Omega[/tex]

So, the resistance rating of the power cord is equal to 40 ohms.

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:

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%

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.

Explanation:

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
