Answer:

The intensity of the light bulb increases

Explanation:

The conductivity of a solution depends on the concentration of ions in solution. This implies that, if the concentration of ions in solution is increased, the conductivity of the solution increases accordingly.

If we add more CuSO4(s) to the CuSO4 solution, the concentration of ions in the solution and consequently the conductivity of the solution increases.

Therefore, the intensity of the light bulb increases.

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:

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%

does the blome receive high levels of precipitation

Answer:

A.Does the biome receive high levels of precipitation?

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

Answer:

B 2:2

Explanation:

Mole ratio is the comparison of the ratio of two compounds or elements in a chemical reaction. In a balanced equation, the moles of a particular compound or element is written as a coefficient. This means that mole ratio is the ratio of the coefficient of two substances in a reaction.

In this balanced chemical equation given as follows:

2CO + 02 → 2CO2

The number of moles/coefficient of carbon monoxide (CO) is 2 while that of carbon dioxide (CO2) is 2.

Hence, the mole ratio of CO to CO2 is 2:2

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: 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 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.

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.
