2.70 g of pure gold nuggets has a net charge of zero, after 1.98% of the electrons have been removed, the net charge is -2.07903 C.

We know that gold has 79 electrons in its neutral state. And the nugget of gold has a mass of 2.70 g. We are to determine its net charge after removing 1.98% of its electrons.

Molar mass of gold = 196.967 g/mol

Number of moles of gold = Mass of gold / Molar mass of gold = 2.70 g / 196.967 g/mol = 0.013708 mol

Number of atoms of gold = Number of moles of gold × Avogadro's number = 0.013708 mol × 6.022 × 10²³ atoms/mol = 8.27042 × 10²¹ atoms

The percentage of electrons removed from gold nugget is 1.98%.

Number of electrons removed = 1.98/100 × Total number of electrons in the nugget= 1.98/100 × 79 × 8.27042 × 10²¹ ≈ 1.29612 × 10²²

Charge on each electron = -1.602 × 10^-19 C

Net charge of the nugget after removing 1.98% of its electrons:

q = n × qee = 1.29612 × 10²² × (-1.602 × 10^-19 C)q = -2.07903 C

Thus, the net charge on the nugget after removing 1.98% of its electrons would be -2.07903 C.

The molar concentration of acetic acid in the vinegar is approximately 0.4185 M. To find the molar concentration of acetic acid in the vinegar, we need to use the equation HC₂H₃O₂ + NaOH → NaC₂H₃O₂ + H₂O.

From the balanced equation, we can see that the ratio between HC₂H₃O₂ and NaOH is 1:1. This means that the number of moles of NaOH used in the titration is equal to the number of moles of HC₂H₃O₂ in the vinegar.

First, let's calculate the number of moles of NaOH used:
Volume of NaOH solution used = 33.49 ml
Molar concentration of NaOH solution = 0.1252 M

Number of moles of NaOH used = Molar concentration × Volume
                           = 0.1252 mol/L × 0.03349 L
                           ≈ 0.004185 mol

Since the ratio between HC₂H₃O₂ and NaOH is 1:1, the number of moles of HC₂H₃O₂ in the vinegar is also approximately 0.004185 mol.

Next, let's calculate the molar concentration of acetic acid (HC₂H₃O₂) in the vinegar:
Volume of HC₂H₃O₂ solution titrated = 10.0 ml = 0.0100 L

Molar concentration of HC₂H₃O₂ = Number of moles / Volume
                             = 0.004185 mol / 0.0100 L
                             ≈ 0.4185 M

Therefore, the molar concentration of acetic acid in the vinegar is approximately 0.4185 M.

The expressions for the equilibrium constants of the reactions are:

a. K = [NH]²/[N₂][H₂]³

b. K = [HBr]²/[Br₂][H₂]

c. K = [H₂][CO₂]/[CO][H₂O]

The equilibrium constant expression for a chemical reaction is derived from the balanced chemical equation. The general form is:

K = [products]^(coefficients of products) / [reactants]^(coefficients of reactants)

a. For the reaction N₂ (g) + 3H₂ (g) ⇌ 2NH₃ (g), the equilibrium constant expression is:

K = [NH₃]² / [N₂][H₂]³

This is because the coefficients of the reactants and products in the balanced equation determine the exponents in the equilibrium constant expression.

b. For the reaction Br₂ (g) + H₂ (g) ⇌ 2HBr (g), the equilibrium constant expression is:

K = [HBr]² / [Br₂][H₂]

c. For the reaction CO (g) + H₂O (g) ⇌ H₂ (g) + CO₂ (g), the equilibrium constant expression is:

K = [H₂][CO₂] / [CO][H₂O]

In each expression, the concentrations (or partial pressures) of the reactants and products are raised to the power of their respective coefficients in the balanced equation. The equilibrium constant provides a quantitative measure of the extent to which the reaction proceeds towards products at equilibrium.

The correct equation representing the radioactive decay of 226Ra is (2)   226Ra → 222Rn + 4He.

This equation correctly represents the radioactive decay process of 226Ra (Radium-226) into 222Rn (Radon-222) and 4He (Helium-4).

In radioactive decay, unstable isotopes undergo a spontaneous process to transform into more stable forms by emitting particles or radiation. In the case of 226Ra, it decays by a process called alpha decay. Alpha decay involves the emission of an alpha particle, which consists of two protons and two neutrons (equivalent to a helium nucleus).

The equation (2) shows that 226Ra undergoes alpha decay, resulting in the formation of 222Rn and the release of an alpha particle (4He). The atomic number and mass number must be conserved in the decay process. Therefore, 226 (atomic number 88) on the left side of the equation decays to 222 (atomic number 86) on the right side, while the mass number also decreases by 4 units.

It's important to note that equation (1) represents an incorrect notation, as it suggests that 226Ra undergoes a transformation to 226Ra89, which is not possible as it implies an increase in atomic number. Equation (3) does not accurately represent the decay of 226Ra. Equation (4) is incorrect as it represents the formation of an isotope that doesn't exist.

All of the calcium iodide will react, and the sodium sulfate will be in excess.

To determine the products of the reaction between sodium sulfate (Na2SO4) and calcium iodide (CaI2), we need to consider the possible double displacement reaction that takes place.

The balanced chemical equation for the reaction is:

Na2SO4 + CaI2 -> 2NaI + CaSO4

According to the equation, sodium sulfate reacts with calcium iodide to produce sodium iodide and calcium sulfate.

Now, let's calculate the moles of each reactant:

Moles of Na2SO4 = molarity * volume = 0.114 mol/L * 0.0350 L = 0.00399 mol

Moles of CaI2 = molarity * volume = 0.125 mol/L * 0.0350 L = 0.00438 mol

From the balanced equation, we can see that the reaction occurs in a 1:1 stoichiometric ratio between Na2SO4 and CaI2. Since the number of moles of CaI2 (0.00438 mol) is slightly higher than the number of moles of Na2SO4 (0.00399 mol), CaI2 is the limiting reactant.

The products of the reaction are sodium iodide (NaI) and calcium sulfate (CaSO4).

C) Presence of ribosomes

The correct option is C) Presence of ribosomes.

Ribosomes are normally absent from the cytoplasm of the axon terminal, whereas they are present in the cytoplasm of the axon. Protein synthesis is carried out by ribosomes, and the fact that they are found in the cytoplasm suggests that protein synthesis can also take place in the axon. Protein synthesis is typically not necessary in the axon terminal, as this structure's main job is to release neurotransmitters and promote communication with nearby neurons or target cells. Due to the absence of ribosomes in the axon terminal, protein synthesis differs between the axon and axon terminal.

Answer: The herbicide (weed killer) takes away a plant's ability to get carbon dioxide. This causes the plant to not be able to produce glucose a source of energy for the plants. Even if there are plenty of water, sunlight, and chloroplasts, the photosynthesis process won't be complete without carbon dioxide. Once in the soil, herbicides can suffer alteration in their structure and composition, due to the action of physical, chemical, and biological processes. This action on the herbicides is the one that will determine their activity and persistence in the soil. Plants damaged by soil sterilant herbicides are the least likely to recover. Plants that show signs of growing out of the problem will likely recover. Plants that appear to lose vigor may not. The survival of damaged plants can be increased by reducing other stresses.
