A sample of gas occupies 20 mL at -109 degree C. What volume does the sample
occupy at 65 °C?

Answers

Answer: V2= 41.2mL

Explanation:

Givens:

* V1= 20ml

* T1 = -109 ⁰C --> K= ⁰C + 273.15 --> 164.15 K

* V2 = ??

* T2= 338.15 K

Use Charles law V1/T1 = V2/T2

Since we are looking for V2 we can rearrange the formula to

V2= (T2 x V1) /T1

V2= (338.15K x 20mL) / 164.15 K

V2= 41.2mL

NOTE:

Temperature should always be in K not in ⁰C or ⁰F

To convert from C to K use

*K= ⁰C + 273.15

Enter your C value in the ( ⁰C ) and you can get K

What mass of aluminum must react with 100 g of copper (ii) phosphate? (10g)

Answers

it would be 10g or 50g

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

Mathematically,

mole =given mass ÷ molar mass

2 Al + 3 Cu[tex]_3[/tex](PO[tex]_4[/tex])[tex]_2[/tex] → Al[tex]_2[/tex] (PO[tex]_4[/tex])[tex]_3[/tex]+ 3 Cu

moles of copper phosphate= 100 g/380.58

                                               =0.26 moles

3 moles of copper sulphate need 2 mole of Al

0.26 moles of copper sulphate need (2/3)×0.26

                                                         =0.17moles

mass of Al= 0.17×26

                  =4.42g

Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

Answers

First, the amount of sunlight received at a given latitude is important. At the equator, the sun is high in the sky and thus very intense. As you move away from the equator, the sun does not reach as high of an angle in the sky, and is less intense. Another important effect near the poles is that during the summer, the sun is up all the time, which boosts the total amount of sunlight received in a day, while in contrast, during the winter, no sunlight is received at all.

There is another, more subtle effect that has to do with latitude. Nature likes to have the temperature be the same everywhere, much like ice cream melts at room temperature or a hot cup of coffee cools to room temperature. The equator is getting blasted with intense sunlight, while the poles are getting a lot less. Nature tries to resolve this imbalance and make the atmosphere the same temperature everywhere. The most efficient way to transfer heat towards the poles depends on latitude and the rotation of the Earth in a complex way. In the tropics (within 30 degrees latitude of the equator), the average daily temperature is mostly constant. Whether you move from north to south, say fro the equator to Mexico, the temperature is mostly the same. Compare that to the midlatitudes (30–60 degrees latitude), where the temperature changes rapidly as you move north or south to the poles. For example, the temperature in Texas is a lot hotter than the temperature in North Dakota.

Another factor is the composition of the surface. Different substances absorb, store, and re-emit heat with different levels of efficiency. The ocean is a major factor, which can either warm or cool the adjacent land. Other surface materials like rock, sand, vegetation, and ice also regulate temperature

The elevations of the surface, specifically mountains effect the climate. Usually, the taller the mountain, the colder the temperature is at the top. Mountains also cause air to flow in certain ways around them, which leads to wet areas on the upwind side and dry areas on the downwind side.

1) How many moles of hydrogen gas can be produced if 0.57 moles of hydrochloric
acid, HCl, reacts with excess solid zinc according to the following chemical
equation?
2 HCl + Zn → Hz + ZnCl2

Answers

Answer: 0.28 mol H2

Explanation:

0.57mol HCl         1mol H2          

                             2mol Hcl

Hydrochloric acid and zinc show the displacement reaction to produce hydrogen gas and zinc chloride. 0.57 moles of hydrochloric acid and excess zinc react to produce 0.28 mol H₂.

What is a displacement reaction?

A displacement reaction is the removal of one of the elements from the reactant with highly active species of the reactivity species to produce the products. It can be a single or double displacement reaction.

The balanced chemical displacement reaction is given as:

2 HCl + Zn → H₂ + ZnCl₂

Here, two hydrochloric acids react with zinc to form one mole of hydrogen gas and one mole of zinc chloride.

Given,

Hydrochloric acid = 0.57 moles

Using proportions to calculate moles as:

If 2 moles of HCl = 1 mole H₂

Then, 0.57 moles = X moles

X = 0.57 ÷ 2

= 0.28 mol H₂

Therefore, 0.57 mole HCl produces 0.28 moles of hydrogen gas.

How many molecules are in 10 grams of sulfur hexafluoride (SF6)? Molar Mass: 146.06 g/mol​

Answers

Answer: 4.123 x 10^22

Explanation:

The first step is to determine how many moles of sulfur hexafluoride (SF6) there are. To do this, you must take the mass of the SF6 (10g) and divide it by the molar mass (146.06).

[tex]10g * \frac{1 mol}{146.06 g}= 0.068465 mol[/tex]

Then you must use Avagadros number to find the number of molecules.

Avagadros number is the number of molecules in 1 mol of a substance, so a simple multiplication will do the trick.

[tex]0.068465mol * \frac{6.022 * 10^{23}}{1mol} = 4.123*10^{22}[/tex]

And that is your answer. There are 4.123 x 10^22 molecules of sulfur hexafluoride in 10g of it.

what is the strongest interparticle force in a sample of so2?

Answers

Answer:

The strongest intermolecular force in sulfur dioxide is dipole-dipole forces.

Explanation:

The interparticle force in [tex]SO_{2}[/tex] (sulfur dioxide) is the dipole-dipole interaction.

What is  dipole-dipole interaction?

Dipole-dipole interaction is a type of intermolecular force that occurs between polar molecules. Polar molecules have a permanent dipole moment, which means they have a partial positive charge on one end and a partial negative charge on the other end. This creates an electrostatic attraction between the partial charges of neighboring molecules. The stronger the dipole moment of a molecule, the stronger its dipole-dipole interaction will be with other polar molecules.

Dipole-dipole interactions are responsible for a variety of physical properties of substances, including their boiling and melting points. Substances with strong dipole-dipole interactions tend to have higher boiling and melting points than substances with weaker interactions. In addition, the strength of dipole-dipole interactions can affect solubility, as polar substances tend to dissolve better in other polar substances due to their ability to form dipole-dipole interactions.
