Answer:

There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.

Explanation:

Edge

There was greater erosion inside the Colorado Rockies situation when there was persistent rain.

Erosion is the loss of soil or rock from the Earth's crust's surface, as well as the movement of the removed material by natural forces (such as wind or water). The term "erosion" is used in its broadest sense to refer to the overall thinning and moulding of all landmasses on the surface of the planet, such as the corrosion of rock in its natural position, the vehicles and public of weathered material, as well as erosion brought on by wind action, marine, as well as glacial processes.

In contrast to the situation within the identical region where there was simply a drizzle, there was greater erosion inside the Colorado Rockies situation when there was persistent rain. Because the volume of a river was raised by the constant rain more than by the drizzle, there is more erosion. The river flowed more quickly as a result of the additional water. A river transfers or erodes more material the quicker it runs.

Therefore, there was greater erosion inside the Colorado Rockies situation when there was persistent rain.

Answer:

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

2 C₃H₈ + 10 O₂ ⇒ 6 CO₂ + 8 H₂O

Explanation:

The combustion reaction is when propane reacts to oxygen to form a compound of carbon and water. If the product of carbon is carbon dioxide, the combustion is called complete. Let's considered the unbalanced combustion reaction.

(Note: I assume is C₃H₈, propane, because C₃H₁₈ doesn´t exist).

C₃H₈ + O₂ ⇒ CO₂ + H₂O

We will start balancing C and H that are just in 1 compound on each side, and finally we will balance O atoms. One way to do so is:

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

We can get a different way of balancing the equation if we, for instance, multiply all the stoichiometric coefficients by 2.

2 C₃H₈ + 10 O₂ ⇒ 6 CO₂ + 8 H₂O

Answer:

The correct answer is "[tex]\frac{0.65}{V} \ percent[/tex]".

Explanation:

The given values are:

[tex]M_r=0.130 \ g[/tex]

[tex]M_o=20 \ g/L\times V(L)[/tex]

     [tex]=20 \ V[/tex]

As we know,

⇒ [tex]Recovery \ percent=\frac{Amount \ of \ substance \ recovered}{Amount \ of \ substance \ originally \ taken}\times 100[/tex]

On substituting the given values, we get

                                [tex]=\frac{0.130}{20 \ V}\times 100[/tex]

                                [tex]=\frac{0.65}{V} \ percent[/tex]

Explanation:

Hey there !

Molecular Weight: 262.86 g/mol

Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L

Number of moles of solution :

number of moles = volume x molarity

number of moles = 1 x 0.3  => 0.3 moles

Therefore:

1 mole Mg₃(PO₄)₂ ------------------- 262.86 g

0.3 moles ----------------------------- mass of Mg₃(PO₄)₂  ??

mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1

mass of Mg(PO₄)₂ => 78.858 g

The most likely outcome of the retrofitting of a nuclear power plant is that it will be able to reprocess its used uranium fuel. Therefore, option C is correct.

A nuclear power plant is a facility that generates electricity by harnessing the heat produced by nuclear reactions. At the heart of a nuclear power plant is the reactor, where a controlled chain reaction of nuclear fission occurs.

Reprocessing is a process by which the used nuclear fuel is chemically treated to separate out and recover the unused uranium and plutonium, which can then be reused as fuel. This reduces the amount of radioactive waste produced by the plant and also extends the life of the uranium fuel.

The fission reactions to fusion reactions is not currently a viable option for power generation, and the idea that a retrofitting would eliminate radioactive wastes is unlikely, as nuclear power plants will always produce some amount of radioactive waste.

Thus, option C is correct.

Answer:

208.125g

Explanation:

Given parameters:

 Number of moles of HCl = 3.75moles

Unknown:

 Mass of CaCl₂ that will be produced = ?

Solution:

The reaction equation is given as:

  2HCl  + Ca(OH)₂   →   CaCl₂ + 2H₂O

Now, to find the mass of CaCl₂, we have to work from the known to the unknown.

The known specie here is the number of moles of HCl;

        2 mole of HCl will produce 1 mole of  CaCl₂

       3.75moles of HCl will produce [tex]\frac{3.75}{2}[/tex]   = 1.875moles

The mass of  CaCl₂;

  Mass of  CaCl₂ = number of moles of  CaCl₂ x molar mass

Molar mass of  CaCl₂ = 40 + 2(35.5) = 111g/mol

  Mass of  CaCl₂ = 1.875 x 111 = 208.125g

Answer:

An amide and water are the products formed

Explanation:

Here, we want to know the possible products that could be formed from the reaction of a carboxylic acid with an amine.

An anime has the functional group NH2 while for an organic acids, we have COOH.

So essentially we want to know the result of these two functional groups coming together to react.

The reaction between these two will form an amide in conjunction with water.

Take for example;

R-COOH + R’-NH2 ———> R-COHN -R’ + H2O

Where R and R’ may be the same or different alkyl or aryl groups

Answer:

Q = 7.7 KJ

Explanation:

The complete question carries the following data:

Specific Heat Capacity of Liquid State = C(l) = 1.45 J/mol.°C

Specific Heat Capacity of Gaseous State = C(g) = 0.65 J/mol.°C

Boiling Temperature = Tb = 88.5°C

Heat of Vaporization = ΔH(vap) = 1.23 KJ/mol

Now, first we calculate the heat required (Q₁) to raise he temperature to boiling point:

Q₁ = n*C(l)*ΔT₁

where,

n = no. of moles = 5.31 mol

ΔT₁ = Temperature difference from 40°C to Tb = 88.5°C - 40°C = 48.5°C

Therefore,

Q₁ = (5.31 mol)(1.45 J/mol.°C)(48.5°C)

Q₁ = 373.4 J = 0.37 KJ

Now, we calculate the heat required (Q₂) to change its phase:

Q₂ = nΔH(vap)

Q₂ = (5.31 mol)(1.23 KJ/mol)

Q₂ = 6.53 KJ

Now, we calculate the heat required (Q₃) to raise he temperature to boiling point:

Q₃ = n*C(g)*ΔT₃

where,

n = no. of moles = 5.31 mol

ΔT₃ = Temperature difference from Tb to 113°C = 113°C - 88.5°C = 24.5°C

Therefore,

Q₃ = (5.31 mol)(0.65 J/mol.°C)(24.5°C)

Q₃ = 84.5 J = 0.08 KJ

So, the total heat required to convert 5.31 mol of this pure substance from a liquid at 40°C to a gas at 113°C is:

Q = Q₁ + Q₂ + Q₃

Q = 0.37 KJ + 6.53 KJ + 0.08 KJ

Q = 7.7 KJ

The total heat required to convert the pure substance from liquid to gas at the given temperature is 814 J.

The given parameters;

The total heat required to convert the pure substance from liquid to gas at the given temperature is calculated as follows;

[tex]Q = nc_l \Delta \theta + nc_g \Delta \theta \\\\ \Delta \theta = (113 - 40) = 73^0 C \\\\Q = (5.31 \ mol \times 1.45 \frac{J}{mol .\ ^0C} \times 73\ ^0C) + (5.31 \ mol \times 0.65 \frac{J}{mol .\ ^0C} \times 73 \ ^0C)\\\\Q = 814 \ J[/tex]

Thus, the total heat required to convert the pure substance from liquid to gas at the given temperature is 814 J.

"Your question is not complete, it seems to be missing the following information;"

How much heat would be required to convert 5.31 mol of a pure substance from a liquid at 40.0°C to a gas at 113.0°C? (molar heat capacity of liquid, C(l) is 1.45 J/mol.⁰C and molar heat capacity of gas, C(g) is 0.65 J/mol.⁰C).
