Liquid tetrabromoethane has a density of 2.96 g/mL. A barometer is constructed using tetrabromoethane instead of mercury. If the atmospheric pressure is 0.971 atm, what is the height of the tetrabromoethane column in the barometer in cm

Answers

Answer 1

16.06 cm is the height of the tetra bromoethane column in the barometer in cm.

What is barometer?

A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure.

Explanation:

Pressure of the liquid column=ρgh

ρ= density of the liquid

h= height of the column

g= due to gravity

the

height of the mercury column corresponding to 0.971 atm

= 0.951×76÷1atm = 73.796 cm

[tex]\rho_1h_1g=\rho_2h_2g[/tex]

2.96 g/mL x 73.796 cm =13.6 g/mL [tex]h_2[/tex]

[tex]h_2[/tex]=16.06148235 =16.06 cm

16.06 cm is the height of the tetra bromoethane column in the barometer in cm.

The weak acid will have fewer ions than the strong acid of similar concentration.

The chemical reactions for a weak acid and a strong acid is given below:

Strong acid: HA → H⁺ + A⁻Weak acid: HA ⇆ H⁺ + A⁻

What are strong and weak acids?

Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.

Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.

Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.

The equation of the dissociation of strong acids and weak acids are given below:

Strong acid: HA → H⁺ + A⁻Weak acid: HA ⇆ H⁺ + A⁻

In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.

A student spilled a bottle of ammonia in one corner of the laboratory. Soon the whole laboratory was felled with pungent irritating small. The students immediately opened the windows and doors and switched on the exhaust fans. After sometime, students got relief. Explain what did actually happen?​

Answers

Answer: Initially when the student spilled the bottle of ammonia the ammonia gas particles diffused with the particles of air in the room. We know that the rate of diffusion of gases is very high. So the entire room filled up with the pungent smell of ammonia.

When he opened the doors and windows and switched on the exhaust fan, the air from the room along with the ammonia gas diffused with the air outside the room.Moreover, outside air entered into the room so the concentration of ammonia gas in the room air reduced.Due to these reasons the student got relief.

The hydrogen emission spectrum is shown below. What is the energy of the

Planck's constant is 6.626 x 10-34 J.s.)
400
750 pm

Answers

Answer:

C.) 4.85 x 10⁻¹⁹ J

Explanation:

To find the energy, you need to use the following equation:

E = hc / w

In this formula,

-----> E = energy (J)

-----> h = Planck's Constant (6.626 x 10⁻³⁴ J*s)

-----> c = speed of light (3.00 x 10⁸ m/s)

-----> w = wavelength (m)

Once you have converted nanometers to meters, you can plug the given values into the equation and solve.

410 nm                1 m
-------------  x  ----------------------  =  4.10 x 10⁻⁷ m
                        1 x 10⁹ nm

E = hc / w

E = (6.626 x 10⁻³⁴ J*s)(3.00 x 10⁸ m/s) / (4.10 x 10⁻⁷ m)

E = 4.85 x 10⁻¹⁹ J

Answers

Answer:

The air flow carries away the carbon dioxide formed during the decomposition. Once accumulated in the furnace or if the air was not allowed to stream through, it begins to react again with the newly formed calcium oxide, equilibrating rather than completing the reaction.

The first step in the formation of all three products is the loss of the ots leaving group to give a carbocation intermediate. this intermediate is resonance-stabilized, and products b and c are generated from a different resonance structure than the one used to generate product a. draw the other resonance structure (using the carbon skeleton provided) and add curved arrow(s) to convert the first resonance structure into the second one.

Answers

The carbocation stabilized by resonance structure and thereby lowers the energy of the carbocation, hydrogen will add to the carbon in the double bond that produces delocalization of electrons.

What is carbocation?

A carbocation is a molecule in which a carbon atom has a positive charge and three bonds.

In general, electrons are stabilized by delocalization. The stabilization energy engendered by delocalization over more than two atoms is called the resonance stabilization energy or simply the resonance energy. The greater the extent of electron delocalization the greater the resonance stabilization.

Electrolytes are substances that have a natural positive or negative electrical charge when dissolved in water.

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

Answers

A compound formed between Magnesium and Sulfur is MgS.

What is a cation?

Cations are positively-charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons).

Magnesium, Mg, is located in period 3, group 2 of the periodic table, and has two electrons on its outermost shell.

On the other hand, sulfur, S, is located in period 3, group 16 of the periodic table, and has six electrons on its outermost shell.

Chemical reactivity is governed by an atom's "desire" to have a stable electron configuration and to have eight electrons in its outermost shell to complete an octet.

In this case, magnesium can complete its octet by giving up those two valence electrons, becoming the magnesium cation.

[tex]Mg^{2+}[/tex], in the process.

Sulfur, which only needs two electrons to complete its octet, will pick up the two electrons coming from magnesium, becoming the sulfide anion,

[tex]S^{2−}[/tex], in the process.

The electrostatic force of attraction will then bring the magnesium cations and the sulfur anions together to form an ionic bond.
