Answer:

Explanation:

I willl go into a bit of detail on the haloform reaction. So the first few steps involve forming an enolate using the base, typically NaOH. THe enolate and go on to do alpha halogenation 3 times. After that, is leaves a trisubstituted alpha methyl carbon with a specific halogen. This is a good leaving group in itself and can carbonyl nucleophillic substitution and turn into a carboxylic acid with a CHZ3- byproduct where Z represents a halogen.

The boiling temperature of bromine is 331.29 K

Explanation:

From the question given above, the following data were obtained:

Br₂ (l) —> Br₂(g)

Enthalpy change (ΔH) = 30.91 KJ/mol

Entropy change (ΔS) = 93.3 J/mol·K

Next, we shall convert 30.91 KJ/mol to J/mol. This can be obtained as follow:

1 KJ/mol = 1000 J/mol

Therefore,

30.91 KJ/mol = 30.91 × 1000

30.91 KJ/mol = 30910 J/mol

Thus, 30.91 KJ/mol is equivalent to 30910 J/mol.

Finally, we shall determine the boiling temperature of bromine. This can be obtained as follow:

Enthalpy change (ΔH) = 30910 J/mol

Entropy change (ΔS) = 93.3 J/mol·K

ΔS = ΔH / T

93.3 = 30910 / T

Cross multiply

93.3 × T = 30910

Divide both side by 93.3

T = 30910 / 93.3

T = 331.29 K

Thus, the boiling temperature of bromine is 331.29 K

Answer:

The volume of the base is 0.05819·x L, where x is the number of moles of base that combines with one mole of sulfuric acid

Explanation:

The volume of the sulfuric acid, V = 25.3 mL = 25.3 × 10⁻³ L

The concentration of the sulfuric acid, c = 2.30 M

The concentration of the base, [tex]c_{base}[/tex] = 1.00 M

Let the mole ratio of the acid to base be 1 : x

The number of moles of sulfuric acid present, n = c × V

∴ n = 2.30 M/L × 25.3 × 10⁻³ L = 0.05819 moles

The number of moles of sulfuric acid present, n = 0.05819 moles

1 mole of sulfuric acid combines with x moles of base

Therefore, 0.05819 moles of sulfuric acid will combine with 0.05819·x moles of base

The number of moles of base, [tex]n_{base}[/tex] = 0.05819·x moles

Therefore, the volume of base, [tex]V_{base}[/tex] = [tex]n_{base}[/tex]/[tex]c_{base}[/tex]

∴  [tex]V_{base}[/tex] = 0.05819·x/1 ≈ 0.05819·x L

The volume of base,  [tex]V_{base}[/tex] ≈ 0.05819·x L.

Explanation:

you can use the mole to mole ratios of aluminum chloride and hydrogen gas,you first have to find the number of moles of hydrogen gas..the number of moles of hydrogen gas are 11.7(23.4/2)

2AlCl3+3H2

2 : 3

x :11.7

3x/3=23.4/3

x=7.8g/mol

then find the number of grams of aluminum chloride

m=n×mr

=7.8×133.341

=1040g

It's nitrogen

Explanation:

cuz it has valence 3 and  a diatomic gas at room temperature

Element X must be nitrogen.

The general formula AlX indicates that aluminum (Al) is reacting with a nonmetallic element represented by X to form a compound.

Since the compound AlX is said to be a diatomic gas at room temperature, it aligns with nitrogen (N2), which is a diatomic gas and a nonmetal.

Among the given options, nitrogen is the diatomic gas that best fits this description.

Answer:

Solid Osmium transition metal reacts with Oxygen gas to produce solid Osmium tetroxide.

Os(s) + 2O₂(g) -> OsO₄(s)

Explanation:

Osmium tetroxide is another way of writing Osmium (VIII) oxide.

Leaving powdered osmium exposed to air in a room will slowly create osmium tetroxide at room temperature.

Similarly, osmium tetroxide vapor will readily be released from a liquid solution at room temperature.

Object named H is harder than Object F due to its thickness.

The object of material H is harder than the object of material F due to the difference in thickness. The thickness of Material Object H is 3 millimeters compared to Material Object F which is 1 millimeter thick, so applying the same amount of force on both objects, Material Object H does not show any change in its structure while on the other hand, the shape of the object F changes due to a lower hardness.

aqueous Magnesium Chloride reacts with liquid Bromide to form aqueous Magnesium Bromide and Chlorine gas

The only option that would increase the pressure of a gas in a container is B. Increasing the temperature of the gas. Option B

To understand which factor would increase the pressure of a gas in a container, we need to consider the relationship between pressure and various variables in the ideal gas law and the kinetic theory of gases.

The ideal gas law states that pressure (P) is directly proportional to the number of gas particles (n), the temperature (T), and inversely proportional to the volume (V) of the container. Mathematically, it can be expressed as:

PV = nRT

where R is the ideal gas constant.

Based on this equation, we can analyze the options given:

A. Decreasing the kinetic energy of the gas: According to the ideal gas law, temperature is directly proportional to pressure. Therefore, decreasing the kinetic energy (which is related to temperature) would decrease the pressure, not increase it.

B. Increasing the temperature of the gas: As mentioned above, temperature is directly proportional to pressure. Increasing the temperature of the gas would increase its kinetic energy, resulting in more frequent and energetic collisions with the container walls, thus increasing the pressure.

C. Decreasing the number of gas particles: According to the ideal gas law, the number of gas particles (n) is directly proportional to pressure. Therefore, decreasing the number of gas particles would decrease the pressure, not increase it.

D. Increasing the volume of the container: According to the ideal gas law, volume (V) is inversely proportional to pressure. Increasing the volume of the container would decrease the pressure, not increase it.
