Which of the following would increase the pressure of a gas in a container?
A. Decreasing the kinetic energy of the gas
B. Increasing the temperature of the gas
C. Decreasing the number of gas particles
D. Increasing the volume of the container
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.

What is Halo form reaction?
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.
c. The reaction Br2 (l) --> Br2 (g) has ΔH = 30.91 kJ/mol and ΔS = 93.3 J/mol·K. Use this information to show (within close agreement) that the boiling point of bromine is 332 K.
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
Boiling temperature (T) =?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
Boiling temperature (T) =?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

Mother is frying fish in the kitchen. The aroma of fried fish can be smelled by Sofea who is sitting in the living room. Explain how the aroma of the fried fish reach the living room.
Answer:
through process of diffusion
Explanation:
air particles and odours move freely in all directions and eventually spreads out thus reaching the sitting room
The process of diffusion causes the particles of the aroma of the fried fish to reach the living room.
What is diffusion?Diffusion can be described as the net movement of anything such as molcules, or energy from a region of higher concentration to a region of lower concentration. Diffusion is generally driven by a gradient in Gibbs free energy or chemical potential.
The concept of diffusion can be used in fields such as physics, chemistry, biology, sociology, economics, and finance. The central idea of diffusion is common that a substance undergoing diffusion spreads out from a point or location at which there is a higher concentration of that substance.
A gradient can be defined as the change in the value of an amount such as concentration, pressure, or temperature with a change in another variable, distance.
A change in concentration over a distance is known as a concentration gradient, and a change in pressure over a distance is known as a pressure gradient.
The Latin word diffusion means "to spread out." Therefore, the aroma of the fried fish diffuses and reaches to lining room.

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.

A student measures the volume of a small irregularly- shaped stone. Which apparatus must be used? a. a measuring cylinder containing water and a ruler only. b. a measuring cylinder containing water only. c. an empty measuring cylinder and a ruler only. d. a ruler only.
Answer:
a measuring cylinder containing water only.
Explanation:
If we want to measure the volume of an irregular object. We need a properly calibrated measuring cylinder filled with water of known volume.
The irregular object is now inserted into the measuring cylinder containing water and the change in the volume of water is noted. The volume of the irregular object is now obtained as;
New volume of water - initial volume of water.
Hence, only a measuring cylinder filled with water is required to measure the volume of a small irregularly- shaped stone.
Explain which intermolecular force is primarily responsible for the unusually high boiling point of H2OH2O. Compare the strengths of intermolecular forces of attraction present in a sample of liquid water to the strengths of intermolecular forces of attraction present in liquid samples of H2SH2S, H2SeH2Se, and H2TeH2Te. Justify your answer using the information presented in both tables, and complete the statements below.
Answer:
See explanation
Explanation:
Intermolecular forces are forces of attraction that exist between molecules of a substance in a particular state of matter.
The dominant intermolecular force of attraction in H2O is the hydrogen bond. The hydrogen bond exists between molecules of a substance when the substance is made of hydrogen atoms bonded to atoms of a highly electronegative element. Hence, strong hydrogen bonding accounts for the high boiling point of water.
The magnitude of hydrogen bonding between molecules depends on the electro negativity of the atoms to which hydrogen is bonded.
The more the electro negativity of the atoms to which hydrogen is bonded, the greater the magnitude of intermolecular hydrogen bonding.
Since the electro negativity of elements decrease down the group, the strength of intermolecular hydrogen bonding between the molecules decreases as follows;
H2O> H2S> H2Se> H2Te
