20 mL of a gas at 200K is heated until the new volume is 55 mL. What is the final temperature of the gas?

answer options:
4.0 K
5.5 K
400K
550 K

Answers

Answer 1

Answer:

550 K

Explanation:

Given the following data;

Original Volume, V1 = 20mL

Original Temperature, T1 = 200K

New Temperature, V2 = 55mL

To find new temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] VT = K[/tex]

[tex] \frac{V1}{T1} = \frac{V2}{T2}[/tex]

Making T2 the subject of formula, we have;

[tex]T_{2} = \frac{V2}{V1} * T_{1}\\[/tex]

Substituting into the equation;

[tex]T_{2} = \frac{55}{20} * 200\\T_{2} = \frac{11000}{20}\\T_{2} = 550K[/tex]

Therefore, the new temperature is 550K.

Which statement best describes John Dalton's use of creativity in his work? He reinterpreted and retested Joseph Proust's results. He used a philosophy to conduct his experiment. He recorded his results as four parts of the atomic theory. He rejected Democritus's idea that matter was composed of atoms.

Answers

Answer: The correct statement is that,

'He reinterpreted and retested Joseph Proust's results'

Explanation:

John Dalton was an English chemist who contributed greatly to the field of Chemistry. He published his theory about atom in 1808.

Dalton was the first person to recognize a workable distinction between the fundamental particle of an element (atom) and that of a compound (molecule). The atomic theory generally summaries the laws of chemical composition which includes:

--> law of constant composition and

---> law of multiple proportions.

John Dalton was being creative in his work by reinterpretation and retesting of Joseph Proust's results. Joseph Proust was a French chemist that first discovered the law of constant composition in 1794. This means that many has started working on the atoms before John Dalton discovery.

From the previous works of Proust, he had studied tin oxides and found that their masses were either 88.1% tin and 11.9% oxygen or 78.7% tin and 21.3% oxygen (these were tin(II) oxide and tin dioxide respectively). Dalton retested and noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of

Dalton reinterpreted it by finding an atomic theory of matter that could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will combine with either one or two oxygen atoms. I hope this helps, thanks.

Methanol, propan-1-ol and ethanol has boiling point of 65 degree celsius, 97 degree celsuis, 87 degree celsuis respectively. A student uses fractional distillation to separate a mixture of these compound. State which liquid will be collected in the second fraction and explain why

Answers

Answer:

ethanol

Explanation:

Methanol has a boiling point of 65°C, propan-1-ol has a boiling point of 97°C and ethanol has a boiling point of 87°C

Fractional distillation is used for separating miscible liquids through the use of the different vapor pressure properties of the liquids. As the mixture is heated up, components start to vaporize according to their boiling points. The component with the least boiling point vaporizes first while the component with the highest boiling point vaporizes last.

This means that methanol would vaporize at the first fraction because it has the lowest boiling point followed by ethanol at the second fraction and then propan-1-ol at the last fraction.

Which series of energy transformations takes place in the circuit when the
siren turns on?


A. Chemical energy - Sound energy - Electrical energy


O B. Electrical energy - Chemical energy - Sound energy


C. Chemical energy - Electrical energy - Sound energy


O D. Sound energy - Electrical energy - Chemical energy

Answers

Answer:

C. Chemical energy - Electrical energy - Sound energy

Explanation:

According to the law of conservation of energy, energy can be transformed i.e changed from one form to another. According to this question, a student builds an electrical circuit, which connects a battery to a siren. Based on this description, the electrical circuit uses ELECTRICAL ENERGY supplied by the CHEMICAL ENERGY in the battery cell.

The electrical energy in the circuit connects the CHEMICAL ENERGY in the battery to the siren, which makes the sound using SOUND ENERGY. In other words, the CHEMICAL ENERGY of the battery powers the ELECTRICAL ENERGY of the circuit to make SOUND ENERGY in the siren. Hence, the order of energy transformation is: Chemical energy - Electrical energy - Sound energy

Answer:

C. Chemical energy - Electrical energy - Sound energy

find the molar mass of this

Answers

Explanation:

Given problem:

Find the molar mass of:

  SO₃ and C₁₀H₈

Solution:

The molar mass of a compound is the mass in grams of one mole of the substance.

To solve this, we are going to add the individual atomic masses of the elements in the compound;

  Atomic mass;

       S = 32g/mol; O = 16g/mol; C = 12g/mol and H = 1g/mol

For  SO₃;

     = 32 + 3(16)

     = 32 + 48

     = 80g/mol

For C₁₀H₈

      = 10(12) + 8(1)

      = 120 + 8

       = 128g/mol
