A student prepared an Earth/Moon model in which the two spheres were 100 m apart. What were the diameters of the spheres?



Answers

Answer:

D₁ = 3.31 m

D₂ = 0.9 m

Explanation:

First, we will find the scaling factor of the model:

[tex]Scaling\ Factor = S.F = \frac{Distance\ between\ Earth\ and\ moon\ in\ Model}{Distance\ between\ Earth\ and\ moon\ in\ Actual}\\S.F = \frac{100\ m}{384400000\ m}\\[/tex]

S.F  = 2.6 x 10⁻⁷

Now, the diameter of 1st sphere, that is Earth will be:

[tex]D_{1} = (S.F)(Actual\ Diameter\ of\ Earth)\\D_{1} = (2.6\ x 10^{-7}\ m)(12742000\ m)\\[/tex]

D₁ = 3.31 m

Now, the diameter of 2nd sphere, that is Moon will be:

[tex]D_{2} = (S.F)(Actual\ Diameter\ of\ Moon)\\D_{2} = (2.6\ x 10^{-7}\ m)(3474200\ m)\\[/tex]

D₂ = 0.9 m

Suppose you are titrating an acid solution with a base solution of known concentration. To calculate the concentration of the acid solution, use three steps.
1. Use the____of base____the endpoint and the known concentration of the base solution to find the_____of base used.
2. Use the_____to find the moles of acid from the moles of base.
3. Divide the moles of acid by the volume of_____the titration to find the concentration of acid.

Answers

Answer:

To calculate the concentration of the acid solution, use three steps.

1. Use the volume of base used at the endpoint and the known concentration of the base solution to find the moles of base used.

2. Use the stoichiometry to find the moles of acid from the moles of base.

3. Divide the moles of acid by the volume of acid used in the titration to find the concentration of acid.

Explanation:

Titration is the process used in volumetric analysis to determine the amount of a substance present in a given sample.

In any titration, a solution of known concentration known as the standard solution is used to react with a solution of of unknown concentration. The reacting volumes of the solutions are then used to calculate the unknown  concentration of the second solution.

In acid-base neutralization reactions, an equivalence point/endpoint of the neutralization titration is obtained and is the point at which the moles of H+ is equal to the moles of OH- . An indicator is used to indicate the equivalence point during a titration by a color change observed in the indicator.

In order to calculate the concentration of an acid, we need to know accurately, use three steps:

1. Use the volume of base used at the endpoint and the known concentration of the base solution to find the moles of base used.

2. Use the stoichiometry of the reaction to find the moles of acid from the moles of base.

3. Divide the moles of acid by the volume of acid used in the titration to find the concentration of acid.

In order to calculate the concentration of a base, use three steps:

1. Use the volume of acid used at the endpoint and the known concentration of the acid solution to find the moles of acids used.

2. Use the stoichiometry of the reaction to find the moles of base from the moles of acid.

3. Divide the moles of base by the volume of base used in the titration to find the concentration of base.

Answers

Answer:

molar mass of  unknown monoprotic acid = 114.1 g / mole.

Explanation:

Note: This question is incomplete and lacks necessary data to solve for the required calculation. However, I have similar question on the internet and seen the question completely and will be using that data to solve for this question in order to solve required calculation. Besides that, complete question asks us to solve for molar mass of the acid used.

Note: I have attached the screenshot of the complete question, please have a look on it in the attachment below.

Calculation:

Volume = 34.81mL

34.81 mL of 0.4346 M potassium hydroxide

= 0.03481 L * 0.4346 mole / L

= 0.01513 mole.

Balance equation:

HA + KOH ----> KA + H2O

As we know from the question,

one mole HA neutralize with 1 mole KOH.

mole of unknown monoprotic acid = 0.01513 mole.

And we know that the formula for mole is:  

mole = mass / molar mass

Making molar mass as the subject:

 Molar mass = mass / mole

Molar mass = 1.726 g / 0.01513 mole

Molar mass = 114.1 g / mole.

So,  

Molar mass of  unknown monoprotic acid = 114.1 g / mole.

Answers

Answer: To be separated using GC, analytes must be volatile.

An air peak is commonly used to determine the dead time when using a TCD detector.

An FID is insensitive to non-combustible gases such as water and carbon dioxide.

A column temperature equal to or slightly above the average boiling point of the sample components results in a reasonable elution time.

Explanation:

The gas chromatography works on the principle of separation of gaseous substances based on the differences of vapor pressure. The thermal conductivity detector works on the principle of detection of effluents from the has chamber and the air peak gives indication of the retention time of the effluents. Flame ionization detector can be used for the detection of organic compounds but insensitive for the detection of halogens, non-combustible substances like carbon dioxide and water. The temperature of the column is kept higher than the average boiling point of the substance so as to attain separation of substances by the differences in the elution time.

The electrons, in redox reaction get partially transferred by one to another element.

What is redox reaction?

A redox reaction occurs when the oxidation states of the substrate change. The loss of electrons or maybe an increase in the oxidation state of a chemical and its atoms is referred to as oxidation. The gain of electrons or a reduction in the oxidation state of either a chemical or its atoms is referred to as reduction. The oxidation as well as reduction process can be seen in same reaction which is introduced as redox reaction.

What is electrons?

Electron can be considered as sub atomic particle which carry negative charge on it.

The given reactions are:

a. Ca(s) + Cl2(g) → CaCl2(s)

b. 4Cu(s) + O2(g) → 2Cu2O(s)

After transferring two electron in both reaction Ca and Cu it will form  CaCl2 and 2Cu2O.

Therefore, after transferring partially electrons one elements get converted into another kind of molecule
