Answer 1

The section of the periodic table in Figure 1 that is most likely to contain element R is section A.

What is the explanation about above answer?Based on the information you provided, element Q is a dull solid with a melting point of 44 °C and does not conduct electricity. These properties suggest that element Q is likely a non-metal. Therefore, the section of the periodic table in Figure 1 that is most likely to contain element Q is section B. This is because non-metals have a low melting and boiling point and they are poor conductors of electricity.Regarding element R, the information provided is its formula R2+ and R3+. These formulas suggest that element R is likely a metal and has a positive charge. Therefore, the section of the periodic table in Figure 1 that is most likely to contain element R is section A. This is because most of the elements in section A are metals and they have positive charges. Since the given information is not enough to determine the position of the element R precisely, however, it's likely that section A is the most probable one.

Fe2O3 Al Al2O3 Fe
Starting Amount in Reaction 3 moles 5 moles ? ?


Determine the maximum amount of Fe that was produced during the experiment. Explain how you determined this amount.

Answers

I think the 279.2g is the maximum amount of Fe produced during the experiment.



However, many other people would say 280 grams because From the equation of the reaction:
Fe203 + 241 - - > 2Fe + 41203
The mole ratio of FezO3 to Al is 1:2.
But 3 moles and 5 moles of reactants respectively started the reaction. Thus, Al is limited in availability and will determine the amount of products that will be produced.
The mole ratio of Al and Fe is 1:1, therefore, a maximum of 5 moles of Fe will be produced from the reaction.
5 moles Fe = 5 x 56 = 280 grams

(part 2 of 2)
How much oxygen would be required?
Answer in units of mol. Answer in units of

Answers

Answer: part 1 of 2

1. The amount required of H₂ = 11.0 g.

2. The amount required of O₂ = 88.0 g.

Explanation:

The balanced equation for the mentioned reaction is:

2H₂(g) + O₂(g) → 2H₂O,

It is clear that 2.0 moles of H₂ react with 1.0 mole of O₂ to produce 2.0 moles of H₂O.

Q1: How much hydrogen would be required to produce 5.5 mol of water?

Using cross multiplication:

2.0 mol of H₂ produce → 2.0 mol of H₂O, from stichiometry.

??? mol of H₂ produce → 5.5 mol of H₂O.

∴ the no. of moles of H₂ needed to produce 5.5 mol of water = (2.0 mol)(5.5 mol)/(2.0 mol) = 5.5 mol.

Now, we can get the mass of H₂ needed to to produce 5.5 mol of water:

mass of H₂ = (no. of moles)(molar mass) = (5.5 mol)(2.0 g/mol) = 11.0 g.

Q2: How much oxygen would be required?

Using cross multiplication:

1.0 mol of O₂ produce → 2.0 mol of H₂O, from stichiometry.

??? mol of O₂ produce → 5.5 mol of H₂O.

∴ the no. of moles of O₂ needed to produce 5.5 mol of water = (1.0 mol)(5.5 mol)/(2.0 mol) = 2.75 mol.

Now, we can get the mass of O₂ needed to to produce 5.5 mol of water:

mass of O₂ = (no. of moles)(molar mass) = (2.75 mol)(32.0 g/mol) = 88.0 g.

What is the value of H-C-H bond angle in ethylene?

Answers

The value of the H-C-H bond angle in ethylene is 117°.

The bond angle is a geometric angle that is formed due to the repulsion between atoms or electrons in a bond. The binding angle for a linear molecule is 180°, for a triangular planar molecule it is 120°, and so on.

The size of the bond angle is affected by the magnitude of the repulsive force of electron pairs in the molecule. The lone pair has a slightly stronger repulsive force than the bonding pair. This happens because the lone pair of electrons is only bound to one atom, so the movement is more flexible.

Back in 1920, one of the most sought-after jobs on the East Coast was as a dial painter at a watch factory. These workers were all female, and they absolutely loved their jobs. These girls were instructed to paint the number on a watch with paint laced with an element called radium.
Years later, many of these workers developed many medical problems with their bones. Some girls lost their jaw bones, and others' bones broke when they walked across a room. Several doctors thought that phosphorus poisoned the girls' bones. Their companies insisted that radium was not damaging their bones to avoid a lawsuit.
Answer the questions below to answer the big questions:

• Was it the radium or the phosphorus that poisoned the girls' bones?

• Were the factories responsible for the girls' sicknesses?


1. Calcium from milk and dairy in the diet is stored in bone tissue until humans are in their mid-20s. Calcium moves around the body as an ion. Doctors suspected that another ion - either phosphorus or radium - was deposited instead of calcium in the workers' bones. How could you use the periodic table to figure this out?

2. In 1920, no one knew about ions. Which substance is more likely to act as calcium ions in bones of young shopworkers?

Use the organizer below to identify important patterns in calcium ions compared to radium and phosphorus and determine which element- phosphorus or radium- is more likely to have replaced the calcium ions in the workers' bodies and caused their ailments.

Characteristics of Calcium Ions:

Reasons it could be Phosphorus:

Reasons it couldn't be Phosphorus:

Reasons it could be Radium:

Reasons it couldn't be Radium:



3. Argument: What do you think is the source of the poisoning, Phosphorus or Radium? From a chemistry perspective, are the shop owners responsible for poisoning the workers with radium?

Answers

1. Calcium has an atomic number of 20 and phosphorus has an atomic number of 15, while radium has an atomic number of 88. This can be used to determine which element was most likely deposited in the workers' bones in place of calcium.

2. Calcium. This is because calcium is an element with an atomic number of 20, meaning it has 20 protons in its nucleus. It is also found in abundance both in the human body and in many foods, making it easy to obtain and store in the body.

Characteristics of Calcium Ions:

- Has a charge of +2

- Located in column 2 of the periodic table

- Atomic number of 20

Reasons it could be Phosphorus:

- Has a charge of +3

- Located in column 3 of the periodic table

- Atomic number of 15

Reasons it couldn't be Phosphorus:

- Has a higher charge than calcium

- Has a different atomic number than calcium

Reasons it could be Radium:

- Has a charge of +2

- Located in column 7 of the periodic table

- Atomic number of 88

Reasons it couldn't be Radium:

- Has a different atomic number than calcium

- Is located in a far different column than calcium on the periodic table

Conclusion
Based on the evidence, it is likely that the source of the poisoning was radium, and from a chemistry perspective, the shop owners were responsible for exposing the workers to this element and, as such, are responsible for their illnesses.

molality of the solution? (Kb of water is 0-.512 degrees c/m)

Answers

The molality of the solution is 3.125 m.

What is the molality of the solution?

Let us recall that the boiling point of the solution is one of the colligative properties and the implication of this is that it depends on the amount of the substance that we can find in the solution.

Note that;

ΔT = K m i

ΔT =  Boiling point elevation

K = boiling constant

m = molality

i = Vant Hoff factor

Then;

ΔT = 101.6 - 100.0

= 1.6°C

Thus;

1.6 = 0.512 * m * 1

m = 1.6/0.512

m = 3.125 m

The mass of liquid oxygen needed to burn 134.8 g of B2H6 is 84.41 mL LOX.

What is liquid oxygen?

Liquid oxygen is a form of oxygen in its liquid state. It is a colorless, odorless, and highly reactive substance that is composed of two oxygen atoms bonded together. It can be made by cooling oxygen gas in a cryogenic process to temperatures below -297°F (-183°C).

What is lewis dot structure ?

A Lewis point structure is a type of diagram used to show the distribution of electrons within a molecule or ion. This structure was first introduced in 1916 by chemist Gilbert N. Lewis. The structure consists of dots representing electrons surrounding the chemical symbols of the atoms in the molecule, indicating the number of bonds each atom can form. The dots are placed in pairs around the element symbol and represent the valence electrons (the electrons at the outermost energy level) of that element. The number of valence electrons of an element can be obtained from the periodic table.

Lewis point structures are used to predict the number and type of bonds that form between atoms in a molecule and to predict the shape of the molecule. By connecting the points of different elements in a molecule, the lewis structure can be used to determine the bond order, or the number of bonds between two atoms. Information about bond order, combined with the arrangement of atoms in space, can be used to determine the molecular structure of a molecule.

Do particles of different masses have the same average speed at a given temperature?

Answers

No, particles of different masses do not have the same average speed at a given temperature.

Temperature is a measure of the average kinetic energy of the particles. Since particles of different masses have different amounts of kinetic energy due to their different masses, they will have different average speeds.

This means that particles of different masses do not have the same average speed at a given temperature. The higher the mass of the particle, the lower the average speed at the same temperature.

This is because when the mass of the particle increases, the amount of kinetic energy also increases, resulting in a slower average speed. On the other hand, particles with a lower mass will have a higher average speed at the same temperature because they have less kinetic energy.

This is why particles of different masses do not have the same average speed at a given temperature.

Answers

The number of Nitrogen molecules required to make 2 * 10^10 molecules of Ammonia is 3 * 10^10. Hence, the correct option is option A.

We are already aware of the simple molecular reaction between hydrogen, nitrogen which produces ammonia which goes as thus -

= N₂+3H₂ = 2NH₃

This molecular reaction tells us that one mole of nitrogen reacts with three moles of hydrogen in order to create two moles of ammonia.

Here, it is given that we have 2 * 10^10 molecules of Ammonia (NH₃).

We also know the formula = No. of atoms/ Avogadro Number = No. of moles

Hence, we can write that -

= No. of atoms of Nitrogen/ 6.022 * 10^23 = 2(2 * 10^10/6.022 * 10^23)

= No. of atoms of Nitrogen/ 6.022 * 10^23 = 0.6 * 10^-13

=  No. of atoms of Nitrogen =  0.6 * 10^-13 * 6.022 * 10^23

= No. of atoms of Nitrogen = 3.6 * 10^10 atoms

(1) Draw all significant resonance structures of cycloserine. In step 1 draw the resonance form that forms a carbocation next to the oxygen. Include lone pairs and charges in your structure.

(2) In step 2 draw the resulting resonance structure. Include lone pairs and charges in your structure.

Answers

Resonance structures of cycloserine can be produced with the help of rotating arrows, produced with a carbocation in step 1 and the resultant resonance structure in step 2 after the double faced arrow.

An antibiotic called cycloserine was discovered in the bacterium Streptomyces orchidaceous. When treating tuberculosis, it is used with other medications. To depict the motion of the electrons in the "original" resonance structure, use curved arrows. By following the arrows, the "new" resonance structure should be a "product" that is automatically created. It will have two resonance structures as depicted in the image attached. Carbocation produced is the step 1 and the resultant compound is the step 2 in the image.

Resonance structures are collections of Lewis structures that explain how the electrons in a polyatomic ion or molecule become delocalized. Because molecules and polyatomic ions frequently have partial charges and fractional bonds, a single Lewis structure frequently falls short of explaining the bonding in a molecule or polyatomic ion.
