68.0 g H₂CC1₂. how many moles

Answers

Answer:

0.801 moles H₂CCl₂

Explanation:

To find the amount of moles, you need to multiply the given mass by the molar mass. The molar mass is a ratio describing the mass (g) per every 1 mole. The molar mass of H₂CCl₂ can be calculated by adding the atomic masses of each atom within the molecule.

When multiplying a number by the molar mass, it is important to arrange the ratio in a way that allows for the cancellation of units (moles should be in the numerator). The final answer should have 3 sig figs like the given value (68.0 g = 3 sig figs).

Atomic Mass (H): 1.008 g/mol

Atomic Mass (C): 12.011 g/mol

Atomic Mass (Cl): 35.453 g/mol

Molar Mass (H₂CCl₄): 2(1.008 g/mol) + 12.011 g/mol + 2(35.453 g/mol)

Molar Mass (H₂CCl₂): 84.933 g/mol

 68.0 g H₂CCl₂             1 mole
-------------------------  x  ------------------  = 0.801 moles H₂CCl₂

The unbalanced reaction for the combustion of pentane (C5H12) is:
C5H12 + O2
CO₂ + H₂O
If the molar mass of pentane is 72 g/mol, how many kilograms of carbon dioxide will be created
when 8.72 kilograms of pentane combust? (Give your answer to the second decimal place)

Answers

The mass (in kilograms) of carbon dioxide that will be created when 8.72 kilograms of pentane combust is 26.64 Kg

We'll beging by writing the balanced equation. This is given below:

C₅H₁₂ + 8O₂ -> 5CO₂ + 6H₂O

The following were obtained from the balanced equation:

Molar mass of C₅H₁₂ = 72 g/mol Mass of C₅H₁₂ from the balanced equation = 1 × 72 = 72 g = 72 / 1000 = 0.072 KgMolar mass of CO₂ = 44 g/mol Mass of CO₂ from the balanced equation = 5 × 44 = 220 g = 220 / 1000 = 0.22 Kg

From the balanced equation above,

0.072 Kg of C₅H₁₂ reacted to create 0.22 Kg of CO₂

How to determine the mass of CO₂ created

From the balanced equation above,

0.072 Kg of C₅H₁₂ reacted to create 0.22 Kg of CO₂

Therefore,

8.72 Kg of C₅H₁₂ will react to creat = (8.72 × 0.22) / 0.072 = 26.64 Kg of CO₂

Thus, 26.64 Kg of CO₂ were created from the reaction

A star is estimated to have a mass of 2.0 ✕ 1036 kg. Assuming it to be a sphere of average radius 6.7 ✕ 105 km, calculate the average density of the star in units of grams per cubic centimeter.

Answers

Taking into account the definition of density, the density of the star is 1,587,553.58 g/cm³.

Definition of density

Density is defined as the  quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

Density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Average density if the star

In this case, you know that:

Mass= 2×10³⁶ kg= 2×10³⁹ g (being 1 kg= 1000 g)Volume of the sphere= 4/3×π×r³ where r is the radius of the sphereVolume of the sphere= 4/3×π×(6.7×10¹⁰ cm)³= 1.2598×10³³ cm³ (being 1 km equals to 100,000 m, 6.7×10⁵ km= 6.7×10¹⁰ cm)

Replacing in the definition of density:

density= 2×10³⁹ g÷ 1.2598×10³³ cm³

Solving:

density= 1,587,553.58 g/cm³

In summary, the density of the star is 1,587,553.58 g/cm³

How does a lithium cation compare to a lithium atom?

The cation is smaller.

Answers

The lithium cation is smaller than lithium atom .

The lithium atom's electronic configuration is as follows:

Li = 1s², 2s

While the following describes the electronic structure of the lithium cation,

Li⁺ = 1s

Some of the reasons why lithium cation is shorter than the corresponding parent atom .

Reduced Energy Levels

The Li atom's valence shell is shown in electronic configurations as being two whereas the Li cation's is one; as a result, the distance between the valence electrons and nucleus has shrunk, resulting in small size.

Less Shielding Effect

Shielding effect refers to the way the core electrons protect the valence electron from nucleus pull. Since there are no core electrons in a cation of lithium, the electrons are more drawn to the proton, which causes the cation to be tiny.

More nuclear charge

Three protons and three electrons make up the Li atom; as a result, three protons will pull three electrons, making the game somewhat balanced. However, once one electron leaves the Li cation, the proton side becomes stronger and exerts more force on the remaining electrons, bringing them closer to the nucleus and shrinking their size.

In this way, a lithium cation became shorter than its corresponding parent atom.

Explanation:

Convert $4.64 per lb to $ per gallon. That would equal around $37.10. Multiply that by 15.70 gallons of strawberries and you'll get $587.47.

15.70 gallons of strawberries would cost approximately $365.40.

To determine the cost of 15.70 gallons of strawberries, we need to convert the volume from gallons to pounds and then multiply by the cost per pound.

First, we need to know the conversion factor between gallons and pounds for strawberries. This conversion factor depends on the density or specific gravity of strawberries, which can vary. Without this information, it is not possible to accurately convert gallons to pounds.

If we assume an average conversion factor of 1 gallon of strawberries weighing approximately 5 pounds, we can estimate the cost. However, please note that this is an approximation and the actual weight of strawberries per gallon may vary.

15.70 gallons * 5 pounds/gallon * $4.64/pound = $365.40

Therefore, based on the approximation, 15.70 gallons of strawberries would cost approximately $365.40.

What are stars?

Stars are massive structures which produce heat and light by nuclear fusion. The term fusion has to do with the combination of one or more nuclei to form a larger nucleus. Heat and light are evolved in the process. The temperature at which this fusion occurs is so great that it is not possible to achieve the fusion reaction here on earth as the outrageously high temperatures required to do so is almost impracticable.

Stars are able to change from one form to another by the process of  stellar evolution. This process could give rise to both the massive stars as well as the smaller size average stars as we have them in the outer space and visible to the astronomers by the use of telescopes.
