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.

Rubia was given a type of inclined plane called a ramp in her science class. Her teacher told her that the ramp should have a mechanical advantage of 3.



Rubia pulled a block up the ramp, but afterward she calculated that the mechanical advantage of the ramp was 2.8 instead of 3. Her teacher said she did not make a mistake. What did Rubia calculate?
A.
the actual operating power of the ramp
B.
the actual mechanical advantage of the ramp
C.
the ideal mechanical advantage of the ramp
D.
the ideal operating power of the ramp

Answers

Answer: B. The actual mechanical advantage of the ramp.

Explanation:

The professor saying that the ramp SHOULD have a mechanical advantage of 3 indicates that that would be the ideal mechanical advantage. Since Rubia calculated it to be 2.8, that means that it is the acutal mechanical advantage. The actual advantage will be reduced from the ieal due to things like friction.

Will the temperatures of the gases be equal? In one to two sentences, use the ideal gas law to explain your answer. (20 points)

Answers

Answer:

The ideal gas law specifies the mechanical behavior of ideal gases. It is capable of calculating the volume of gases produced or consumed.

In chemical equations, these equations are widely used to convert between volumes and molar quantities.

Use ideal gas law

Therefore

When n increases, T decreases, so, n is 1 for and 0.5 for , implying that is hotter.

The temperatures of the gases will not be equal.

The ideal gas law specifies the mechanical behavior of ideal gases. It is capable of calculating the volume of gases produced or consumed.

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.

Why do different places on Earth have different climates?

Your answer should include 1 paragraph to explain the claim, evidence, and reasoning. Be sure to check your grammar and spelling!​

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.

Answers

Hydro-kinetic energy has advantages of being a clean, domestic, and renewable source with effective production. The disadvantages have been affected marine environment, along with water quality, and electricity on drought.

Hydro kinetic energy has been the energy produced by the movement of water bodies in the form of tides, waves, and oceanic current. The hydro-kinetic energy has been composed with high energy entrapped in the water bodies.

Some of the advantages of hydro-kinetic energy has been:

It has been a clean energy source and has been  pollution free.It has been used as domestic source of energy.It has been a renewable source of energy.It has been produced by the tidal waves, thus can be produced effective and in need.

Some of the disadvantages of hydro-kinetic energy has been:

Application of water bodies affects the marine environment.It has been producing low BOD and thereby affects the water quality.Conditions such as drought result in the affected electricity production.
