Which substance below would have particles with the SLOWEST average velocity at 300 K?
Fluorine, F2
Chlorine, Cl2
Methane, CH4
Xenon, Xe
Answer:
Likely Xenon, [tex]\rm Xe[/tex].
Explanation:
The average kinetic energy of particles of a gas at a given temperature and pressure should be the same (regardless of the exact composition of the particle.)
For example, let [tex]m_1[/tex] and [tex]m_2[/tex] denote the mass of each particle of two gases, and let [tex]v_1[/tex] and [tex]v_2[/tex] denote the average speed of particles of each gas.
Average kinetic energy of particles of the first gas: [tex]\displaystyle {\rm KE_1} = \frac{1}{2}\, m_1 \cdot ({v_1})^{2}[/tex].
Average kinetic energy of particles of the second gas: [tex]\displaystyle {\rm KE_2} = \frac{1}{2}\, m_2 \cdot ({v_2})^{2}[/tex].
If the temperature of these two gases are the same, [tex]\rm KE_1 = KE_2[/tex]. Hence:
[tex]\displaystyle \frac{1}{2}\, m_1 \cdot ({v_1})^{2}= \frac{1}{2}\, m_2 \cdot ({v_2})^{2}[/tex].
[tex]\displaystyle \frac{v_1}{v_2} = \frac{\sqrt{m_2}}{\sqrt{m_1}}[/tex].
In other words, the average velocity of particles of each gas (at the same temperature and pressure) is inversely proportional to the square root of the mass of one particle of each gas.
Similarly, at the same temperature and pressure, particles of the four gases in this question would have the same average kinetic energy. However, the gas with the largest per-particle mass would have the slowest average velocity for its particles.
Look up the relative atomic mass of the particles:
[tex]\rm F[/tex]: [tex]18.998[/tex].[tex]\rm C[/tex]: [tex]12.011[/tex].[tex]\rm H[/tex]: [tex]1.008[/tex].[tex]\rm Cl[/tex]: [tex]35.45[/tex].[tex]\rm Xe[/tex]: [tex]131.293[/tex].Calculate the formula mass of each gas. That value would be proportional to the average mass of each particle of the gas:
[tex]\begin{aligned}M(\rm F_2) &= (2 \times 18.998)\; \rm g\cdot mol^{-1}\\ &= 37.996\; \rm g\cdot mol^{-1}\end{aligned}[/tex].[tex]\begin{aligned}M(\rm Cl_2) &= (2 \times 35.45)\; \rm g\cdot mol^{-1}\\ &= 70.90\; \rm g\cdot mol^{-1}\end{aligned}[/tex].[tex]\begin{aligned}M(\rm CH_4) &= (12.011 + 4 \times 1.008)\; \rm g\cdot mol^{-1}\\ &= 16.043\; \rm g\cdot mol^{-1}\end{aligned}[/tex].[tex]\begin{aligned}M(\rm Xe) &= 131.293\; \rm g \cdot mol^{-1}\end{aligned}[/tex].Among these four gases, each particle of xenon, [tex]\rm Xe[/tex], has the largest per-particle mass. Hence, at the same temperature and pressure, particles of Xenon would have the slowest average velocity among these gases.

Explanation:
Arsenate (AsO43-) is structurally and chemically similar to inorganic phosphate (PO43-), and many enzymes that act on phosphate will also use arsenate as a substrate if it is available. However, unlike phosphates, organic compounds of arsenate are kinetically unstable. For example, acyl phosphates (such as 1,3-bisphosphoglycerate) require an enzyme to catalyze phosphate hydrolysis on a biologically relevant timescale, but acyl arsenates hydrolyze almost instantaneously in water without an enzyme.
a) Predict the effect on the net reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase if phosphate were replaced by arsenate.
b) Write a balanced overall equation for the conversion of glucose to pyruvate in the presence of ATP, ADP, NAD+, and arsenate.
c) Arsenate is extremely toxic to most organisms. Based on your answers above, explain why.
Answer:
A) The effect on the net reaction catalyzed by glyceraldehyde is that
The 1-arsen0, 3-phosphoglycerate will decompose without enzymes hence no ATP will be formed in the reaction ( phosphoglycerate Kinase )
B) There will be no conversion of ADP to ATP from the conversion of glucose to pyruvate hence No balanced overall equation can be derived
C ) Arsenate is very toxic to most organisms and it is used mostly regarded as poisons during the formation of glycolysis, it forms 1-arsen0, 3-phosphoglycerate which hinders the formation of ATP because it is unstable and will hydrolyze quickly, this will also lead to the reduction in oxygen in cells thereby leading to the death of cells

The student recorded the mass of the cup + sample incorrectly and started with 2.20 g of hydrated compound but used 2.00 g in the calculations. Explain how this error will affect the calculation for the number of moles of water in the hydrate? Will the final answer be artificially high or low? How do you know?
Answer:
low
Explanation:
We were informed in the question that the student had incorrectly recorded the mass of cup + sample as 2.20 g but inadvertently used 2.00 g in the calculations.
This error will cause a slight decrease in the mass of water and ultimately decrease the number of moles of water in the hydrate.
What i am saying is that the number of moles of water obtained in the calculation will be artificially low.

Explanation:
Circuit A has a resistance of 7.5 ohms, and circuit B has a resistance of 5 ohms. Which statement about the circuits must be correct?
If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is equal to the current in circuit B
If the current in circuit A is equal to the current in circuit B, then the voltage in circuit A is less than the
voltage in circuit B
If the current in circuit A is less than the current in circuit B, then the voltage in circuit A is less than the
voltage in circuit B
If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is less than the
current in circuit B
Answer:
If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is less than the current in circuit B
Explanation:
To know the the correct answer to the question, do the following:
Case 1: Let the circuit A and B have equal voltage say 24 V.
For Circuit A:
Voltage (V) = 24 V
Resistance (R) = 7.5 ohms
Current (I) =?
V = IR
24 = I × 7.5
Divide both side by 7.5
I = 24 / 7.5
I = 3.2 A
For Circuit B:
Voltage (V) = 24 V
Resistance (R) = 5 ohms
Current (I) =?
V = IR
24 = I × 5
Divide both side by 5
I = 24 / 5
I = 4.8 A
Thus for the same voltage, current in circuit A is less than the current in B.
Case 2: Let circuit A and B have equal current say 2 A
For circuit A:
Current (I) = 2 A
Resistance (R) = 7.5 ohms
Voltage (V) =?
V = IR
V = 2 × 7.5
V = 15 V
For Circuit B:
Current (I) = 2 A
Resistance (R) = 5 ohms
Voltage (V) =?
V = IR
V = 2 × 5
V = 10 V
Thus, for the same current, the voltage in circuit A is greater than the voltage in B
Case 3: Let circuit A have a current of 4 A and circuit B have a current of 5 A
For circuit A:
Current (I) = 4 A
Resistance (R) = 7.5 ohms
Voltage (V) =?
V = IR
V = 4 × 7.5
V = 30 V
For circuit B:
Current (I) = 5 A
Resistance (R) = 5 ohms
Voltage (V) =?
V = IR
V = 5 × 5
V = 25 V
Thus, when the current in circuit A is less than the current in circuit B, the voltage in circuit A is greater than the voltage in circuit B.
From the illustrations above and the options given in the question, the current answer is:
If the voltage of circuit A is equal to the voltage of circuit B, then the current in circuit A is less than the current in circuit B

-Atoms combine to make all the substances on Earth.
-Atoms of all substances have the same chemical properties.
-Atoms are easily destroyed when matter is cooled or heated.
-Atoms come in different sizes, but most are visible using a simple hand lens.
Answer: Atoms combine to make all the substances on Earth.
Explanation:
Atom is a smallest entity of any matter. The atoms of different elements combine together in order to form new substances. The atoms have electrons, neutrons, as well as protons. The atoms are combined by the chemical bond. When two or more atoms combine they form a molecule. The molecules combine to form compound. Atoms cannot be broken into sub parts. The two atoms of hydrogen and one of oxygen forms water which is an essential liquid on planet earth. Other substances like carbon dioxide, coal, and sodium chloride.

g As the number of nonvolatile solute particles in a given volume of solution increases, A) the boiling point increases and the vapor pressure at 25°C increases. B) the freezing point decreases and the vapor pressure at 25°C decreases. C) the freezing point increases and the vapor pressure at 25°C increases. D) the boiling point decreases and the vapor pressure at 25°C decreases. E) the freezing point increases and the vapor pressure at 25°C decreases.
Answer:
B) the freezing point decreases and the vapor pressure at 25°C decreases.
Explanation:
Colligative properties are those properties that depend on the amount of solute in solution. Both freezing point and vapour pressure are colligative properties.
As the number of nonvolatile solute particles increases, the freezing point of the solution decreases. This is known as freezing point depression.
Similarly, "Vapor pressure is a colligative property, so the vapor pressure of solutions is directly proportional to the amount of solute present in a solution. When a solute is present in a solvent, the vapor pressure is lowered because fewer solvent molecules are present at the top of the solution" (Lumen Learning).

Answer:
Part A: Protonation, Protonation
Part B: An elimination, A substitution
Explanation:
The dehydration ethanol and the condensation of ethanol all begin from the protonation of ethanol. This is because, water is a good leaving group. Thus, the protonation of the -OH moiety of the molecule is the first step in each mechanism.
The dehydration of ethanol is an elimination reaction because it involves the loss of H-O-H from the ethanol molecule while the condensation of ethanol is an substitution reaction because the -OH moiety is replaced by -OCH2CH3.
