Answer:  6.022 × 10²³

Explanation:

Avogadro's Number (6.022 × 10²³ atoms/mole) is the number of atoms in any mole of a substance.

The B: oxygen in O2 is oxidized in the given redox reaction. In a redox reaction, oxidation is the loss of electrons, while reduction is the gain of electrons. In the given reaction, oxygen gains electrons from sulfur, which means oxygen undergoes reduction. At the same time, sulfur loses electrons to oxygen, which means sulfur undergoes oxidation. Therefore, the element that is oxidized in this reaction is sulfur.

To describe the answer more accurately, it should be noted that the question is asking about which element is oxidized, not which compound or molecule. The reactants in the reaction are 2 molecules of H2S and 1 molecule of O2, and the products are 2 molecules of H2O and 1 molecule of S. It is the oxygen in O2 that is oxidized, as it gains electrons during the reaction.

If terrestrial processes are responsible for the remaining Carbon for the net balance of the Carbon cycle, then the terrestrial surface is likely a net sink of 1.8 Gt of Carbon.

To determine this, we can calculate the net balance of Carbon in the terrestrial and ocean processes and then compare it to the increase in the atmosphere.

Terrestrial processes:-
Photosynthesis: +120 Gt
Decomposition: -60 Gt
Respiration: -60 Gt

Ocean processes:-
Uptake: +92 Gt
Release: -91 Gt

Anthropogenic sources:
Fossil fuel use and land use change: -6 Gt

Atmospheric increase: -3.2 Gt

The net balance of terrestrial processes: 120 - 60 - 60 = 0 Gt
The net balance of ocean processes: 92 - 91 = 1 Gt
The net balance of anthropogenic sources: -6 Gt

Now, we can add up the net balances and compare it to the atmospheric increase:-
0 + 1 - 6 = -5 Gt

Since the atmosphere is increasing by 3.2 Gt, there is a difference of 3.2 - (-5) = 8.2 Gt. The terrestrial processes are responsible for the remaining 8.2 - 1 = 7.2 Gt. However, we know the net balance of terrestrial processes is 0 Gt.

Therefore, the terrestrial surface must be a net sink of 1.8 Gt of Carbon (7.2 - 5.4 = 1.8 Gt) to achieve the net balance of the Carbon cycle.

Answer: a. BaO

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here element barium is having an oxidation state of +2 called as \(Ba^{2+}\) cation and \(O^{2-}\) is an anion with oxidation state of -2. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral \(BaO\)

For (a), the molecule H3C-C-C-H3C-CH3-CH3, you would expect 1H NMR signals and 3 13C NMR signals. For (b), the molecule (E)-O-H3C-CH3-CH3-CH3, you would expect 3H NMR signals and 6 13C NMR signals. For (c), the molecule O-CH3CCH3, you would expect 4H NMR signals and 4 13C NMR signals.

The number of signals in the 1H and 13C spectra of a molecule is determined by the number of chemically equivalent protons and carbons, respectively. For molecule (a) H3C C C H3C CH3 CH3, there are 3 sets of chemically equivalent protons (the two CH3 groups on the ends and the two CH3 groups attached to the central carbon) and 3 sets of chemically equivalent carbons (the two terminal carbons and the central carbon). Therefore, we would expect 3 signals in the 1H spectrum and 3 signals in the 13C spectrum. For molecule (b) (E) O H3C CH3 CH3 CH3, there are 4 sets of chemically equivalent protons (the three CH3 groups and the two protons attached to the oxygen) and 4 sets of chemically equivalent carbons (the three terminal carbons and the carbon attached to the oxygen). Therefore, we would expect 4 signals in the 1H spectrum and 4 signals in the 13C spectrum. For molecule (c) O CH3CCH3, there are 2 sets of chemically equivalent protons (the two CH3 groups) and 2 sets of chemically equivalent carbons (the two carbons attached to the oxygen). Therefore, we would expect 2 signals in the 1H spectrum and 2 signals in the 13C spectrum.

Answer:

Energy is transferred from one object to another when a reaction takes place.

Explanation:

Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few.  

The answer could be It is a well known fact that energy can neither be created and nor be destroyed but can be transformed from one form to another.

Now talking about your example in a typical light bulb electrical energy is converted into light energy and heat energy. Now when the electric current flows through the conductor/filament in the light bulb,this would cause vibrations and the free ions are more likely to go to an higher energy level,and when the ions come back to their original state,the difference in the two energy levels is usually emitted as a photon,thus light energy is obtained and the heat energy is the energy dissipated as a result of flow of electricity through the conductor.

Anything that gets transformed into light energy or in better words ElectroMagnetic Energy would be a result of this.

The solubility of a compound in a particular solvent depends on several factors, including the polarity of the solvent and the solute. Nonane is a nonpolar solvent, which means that it cannot dissolve polar compounds effectively. In general, compounds with nonpolar properties are more soluble in nonane compared to polar compounds.

1-pentanol, ethanol and acetic acid are polar compounds because they contain a hydroxyl group (-OH) or carbonyl group (C=O) that makes them more soluble in polar solvents such as water. Benzene and ethyl methyl ketone are nonpolar compounds because they lack any polar functional groups and contain only carbon and hydrogen atoms.
Based on their polarities, we can predict that benzene and ethyl methyl ketone will be the most soluble in nonane because nonane is a nonpolar solvent. The polar compounds (1-pentanol, ethanol, and acetic acid) will not dissolve well in nonane due to their polarity. Acetic acid may have some solubility in nonane because it has a relatively small polar functional group and a large nonpolar hydrocarbon chain. In conclusion, the most soluble compound in nonane is likely to be benzene or ethyl methyl ketone, both of which are nonpolar. The polar compounds are not expected to be very soluble in nonane due to the nonpolar nature of the solvent.

Using the change of base rule to find the logarithm to four decimal places. the correct answer is 11.4235.

To find the logarithm of 143.2 using the change of base rule, we can choose any base we prefer. Let's use base 10 and natural logarithm (base e) for this calculation.

First, we'll use the change of base formula, which states that log(base b) x = log(base c) x / log(base c) b. In this case, we'll calculate log(base 10) 143.2.

We'll use the natural logarithm (ln) as our intermediary step. The natural logarithm of 143.2 can be calculated as ln(143.2).

Using a calculator, we find that ln(143.2) is approximately 4.9628.

Next, we need to calculate log(base 10) e, which is the logarithm of e with base 10. Using a calculator, we find log(base 10) e is approximately 0.4343.

Finally, we apply the change of base formula:

log(base 10) 143.2 ≈ ln(143.2) / log(base 10) e
                ≈ 4.9628 / 0.4343
                ≈ 11.4235

Rounding to four decimal places, the logarithm of 143.2 using base 10 is approximately 11.4235.

2) The dependent variable = The time it takes for one pendulum swing

3) The independent variable = The length of the pendulum string with weight at the bottom

Explanation:

The relationship between the length of the pendulum string and the time it takes for one pendulum swing is giving as follows;

\(T = 2 \cdot \pi \cdot \sqrt{\dfrac{L}{g} }\)

Where;

T = The period of oscillation = The time to complete one oscillation =Two swings of the pendulum

L = The length of the pendulum

g = The acceleration due to gravity

Therefore, the time it takes for one pendulum swing is directly proportional to the square root of the length of the pendulum

The dependent variable = The time it takes for one pendulum swing

Th independent variable = The length of the pendulum string with weight at the bottom.

t = 0.11 min

Thus, particle take 0.11 min to travel 158 m distance.

To determine the mass of glucose needed to prepare a 0.352 molal solution, we first need to understand what a molal solution is.

A molal solution is a solution where 1 mole of solute is dissolved in 1 kilogram of solvent.

Given that the molality (molal concentration) is 0.352 molal, we know that there are 0.352 moles of glucose per kilogram of water.

To find the mass of glucose, we need to convert the given amount of water to kilograms. Since 1 gram is equal to 0.001 kilograms, we divide the given mass of water (728.1 g) by 1000 to convert it to kilograms:

728.1 g / 1000 = 0.7281 kg

Now, we can calculate the mass of glucose by multiplying the molality by the mass of water:

0.352 molal * 0.7281 kg = 0.2562 moles

The molar mass of glucose (C6H12O6) is 180.16 g/mol.

To find the mass in grams, we multiply the moles of glucose by the molar mass:
0.2562 moles * 180.16 g/mol = 46.22 g
Therefore, to prepare a 0.352 molal solution, you would need to add 46.22 grams of glucose to 728.1 grams of water.
