What are prevailing winds

Answer:

36.2 K

Explanation:

Step 1: Given data

Step 2: Convert T₁ to Kelvin

We will use the following expression.

K = °C +273.15

K = 38 °C +273.15 = 311 K

Step 3: Calculate T₂

We will use Gay Lussac's law.

P₁/T₁ = P₂/T₂

T₂ = P₂ × T₁/P₁

T₂ = 1.0 atm × 311 K/8.6 atm = 36.2 K

A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds and a type of fat containing a high proportion of fatty acid molecules with at least one double bond, considered to be healthier in the diet than saturated fat.

Answer:

4.0561×0.03÷63.5= 0.001916 mol cu

A coin is 3.00% Cu by mass. If the mass of the coin is 4.0561g, moles of Cu does it contain 0.001916 mole of Cu.

It is the most fundamental characteristic of matter and one of the fundamental quantities in physics.

Mass is a term used to describe how much matter is there in a body. The kilogramme is the SI unit of mass (kg). A body's mass does not alter at any point in time.

Given mass of coin = 4.0561g , moles =? , Cu by mass= 3.00%

4.0561×0.03÷63.5= 0.001916 mole Cu.

Thus, A coin is 3.00% Cu by mass. If the mass of the coin is 4.0561g, moles of Cu does it contain 0.001916 mole of Cu.

Answer:

B. are openings in the earth surface

Answer: 90 degrees        .

Answer:

0.17 moles

Explanation:

In the elements of the periodic table, the atomic mass = molar mass. Ex: Atomic mass of Carbon is 12.01 amu which means molar mass of Carbon is also 12.01g/mol.

In order to find the # of moles in a 12 g sample of NiC-12, we will need to multiply the number of each atom by its molar mass and then add the masses of both Nickel and C-12 found in the periodic table:

Since there's just one atom of both Carbon and Nickel, we just add up the masses to find the molar mass of the whole compound of NiC-12.

There's 12g of NiC-12, which is less than the molar mass of NiC-12, so the number of moles should be less than 1. In order to find the # of moles in NiC-12, we need to do some dimensional analysis:

P.S. C-12 or C12 just means that the Carbon atom has an atomic mass of 12amu and a molar mass of 12g/mol, or just regular carbon.

Answer:

the solubility of the gas increases

Explanation:

as the kinetic energy of a gaseous solute increases,its molecules has a greater chance of escaping the attraction of the solvent molecules and return to the gas phase..which lead to the solubility of the gas been Increase as the temperature decreased .

This reaction is different in that the carbon undergoes an incomplete combustion as opposed to complete combustion where carbon is fully oxidized. A caveat: incomplete combustion products in general can be difficult to predict without sufficient information, as it's not uncommon to obtain a mixture of different products.

Here, we are told that solid carbon is burned in limited air to produce a gas. I am presuming that, in the equation that's given, the "0" represents a blank where you must fill in a chemical symbol. In this case, our equation would be: 2C(s) + O₂(g) → 2CO(g).

There is not enough information here to provide the numerical answers to the two questions. From the words in the question (e.g., "is different" and "this time"), it would seem that this question is an excerpt from a larger or preceding question where specific numbers had been provided or computed.

However, it's possible to make some general observations on how one may go about answering these questions if one had more information.

Since we're to assume that oxygen is the limiting reagent, if one is given the amount of solid carbon (either in mass, moles, or number of atoms), it's possible to determine the moles of CO(g) that's produced since C and CO have an equal stoichiometric ratio. So, for example, if one burns 2 moles of C(s), then 2 moles of CO(g) would be produced.

But, there is still not enough information to compute the volume of CO gas if this is the line of questioning. We don't know, for instance, the temperature or pressure of the reaction conditions. In fact, the only way it would be possible to answer this would be if you were given beforehand a conversion factor that relates the volume of CO(g) to its quantity (e.g., to assume that one mole of gas occupies x liters).

As for the second question, this would depend on what you know about the quantity of the C(s) reacted and/or the quantity (or volume, from question a) of CO(g) produced. If you can get the number of moles of C(s) reacted or CO(g) produced, the number of moles of O₂(g) used up: It would be half the number of moles of C(s) reacted or half the number of moles of CO(g) produced). Again, it's impossible to determine the volume of O₂(g) using just the information provided here, so I suspect that you must have further information relating gas quantity to volume. As we did with CO(g), the volume of O₂(g) used up can be found using whatever conversion factor you have.

If you have any further information or questions, please feel free to follow up.  

This reaction is distinct in that the carbon undergoes incomplete combustion rather than complete combustion, in which the carbon is completely oxidized. incomplete combustion products in general can be difficult to predict without sufficient information, as a mixture of different products is not uncommon.

Combustion is a chemical reaction in which a substance reacts with oxygen to produce heat. Combustible refers to a substance that can be burned. It is also known as a fuel. The fuel can be either solid, liquid, or gas.

We're told that solid carbon is burned in a small amount of air to produce a gas.

This would be determined by the amount of C(s) reacted and/or the amount (or volume, from question a) of CO(g) produced. If you can calculate the number of moles of C(s) reacted or CO(g) produced, you can calculate the number of moles of O2(g) consumed: It would be half the amount of C(s) reacted or half the amount of CO(g) produced).

Thus, This reaction is distinct in that the carbon undergoes incomplete combustion rather than complete combustion.

Answer:

• The molar amount of the gas

Explanation:

Hello!

In this case, according to the ideal gas law:

[tex]PV=nRT[/tex]

Whereas P stands for pressure, V for volume, n for the molar amount of the gas, R for the universal gas constant and T for the temperature, we can see that as pressure, volume and temperature are given, we can compute the molar amount of the gas as shown below:

[tex]n=\frac{PV}{RT}[/tex]

Since R is a constant always.

Answer: The concentration of this solution is [tex]114g/dm^3[/tex]

Explanation:

Concentration of a solution is defined as the number of grams of solute dissolved per liter of the solution.

Given : mass of solute = 28.4 g

volume of solution = [tex]250cm^3=0.25dm^3[/tex]      [tex]1cm^3=0.001dm^3[/tex]  

[tex]Concentration=\frac{28.4g}{0.25dm^3}=114g/dm^3[/tex]

Thus the concentration of this solution is [tex]114g/dm^3[/tex]

By definition and change of units, the concentration of this solution is 113.6 [tex]\frac{grams}{dm^{3} }[/tex].

Chemical concentration determines the ratio of solute and solvent in a chemical solution and is defined as the ratio of the amount or volume of solute to the amount of solution. The more solute, the higher the concentration in a solution.

In this case, you know:

mass of solute= 28.4 g

volume of solution= 250 cm³= 0.25 dm³ (being 1 cm³= 0.001 dm³)

Then, the concentration can be calculated as:

[tex]concentration= \frac{28.4 grams}{0.25 dm^{3} }[/tex]

Concentration= 113.6 [tex]\frac{grams}{dm^{3} }[/tex]

Thus the concentration of this solution is 113.6 [tex]\frac{grams}{dm^{3} }[/tex].
