Answer:

The activation energy increases how quickly the reaction will  progress.

Explanation:

The activation energy of a chemical reaction is intimately linked to its rate. Particularly, the greater the activation energy, the slower the chemical reaction will be. The reason is: molecules can only finish the reaction as soon as they have reached the peak of the activation energy barrier. Many reactions possess such huge activation energies that they practically don't advance at all without an input of energy.

The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.

The pillar of sustainability broken by recycling electronics in India is environmental sustainability. Implementing a law that restricts electronics recycling to the US would not necessarily be the most effective solution, as it overlooks the complex global dynamics of electronic waste management.

Recycling electronics in India often involves improper disposal methods, such as burning or dismantling without proper safety measures. This leads to environmental pollution, including the release of hazardous substances into the air, soil, and water, thus violating the principle of environmental sustainability.

However, simply mandating that electronics can only be recycled in the US may not be the most optimal solution. Electronic waste is a global issue, and restricting recycling to a single country disregards the fact that electronic products are manufactured and consumed worldwide. A more comprehensive approach to addressing electronic waste would involve international cooperation, strict regulations, and monitoring of recycling practices to ensure they meet environmental standards.

Efforts should focus on improving recycling practices globally, including promoting responsible electronic waste management, developing sustainable recycling infrastructure in multiple countries, and encouraging the adoption of safe and environmentally friendly recycling practices. This approach would foster global sustainability and address the challenges associated with electronic waste disposal more effectively than a geographically limited restriction.

The given chemical equation is an unbalanced redox reaction that takes place in basic solution. The oxidation state of Al changes from -1 to +3, while that of C changes from +2 to -2.

To balance the equation, we first balance the number of carbon and hydrogen atoms on each side by adding a coefficient of 2 in front of H₂CO. This gives:

AlH₄-(aq) + 2H₂CO(s) → Al₃+ (aq) + 2CH₃OH(aq)

Next, we balance the hydrogen and oxygen atoms in the equation by adding OH- ions. We add four OH- ions to the right-hand side of the equation to balance the hydrogen atoms, and two more OH- ions on the left-hand side to balance the oxygen atoms. This gives:

AlH4-(aq) + 2H₂CO(s) + 6OH-(aq) → Al₃+ (aq) + 2CH₃OH(aq) + 4H₂O(l)

The balanced equation has a coefficient of 6 for OH- ions, which indicates that 6 hydroxide ions are needed to balance the reaction in basic solution.

The correct answer is 6 different tripeptides can be formed when one isoleucine, one alanine, and one glycine react.

To determine the number of different tripeptides that can be formed when one isoleucine, one alanine, and one glycine react, we need to consider the possible arrangements of these amino acids.

A tripeptide is a peptide composed of three amino acids linked together by peptide bonds. In this case, we have three specific amino acids: isoleucine, alanine, and glycine. To calculate the number of different tripeptides, we need to consider the possible permutations of these three amino acids.

The formula to calculate permutations is n!/(n1! * n2! * n3! * ... * nk!), where n is the total number of items and n1, n2, n3, etc., represent the number of repetitions of each item. In this case, n is 3, as we have three different amino acids.

Now, let's calculate the permutations:

n! = 3! = 3 * 2 * 1 = 6

However, we also need to consider the number of repetitions of each amino acid. We have one isoleucine, one alanine, and one glycine. Therefore, we have:

n1! = 1! = 1

n2! = 1! = 1

n3! = 1! = 1

Plugging these values into the formula, we get:

3!/(1! * 1! * 1!) = 6/(1 * 1 * 1) = 6/1 = 6

Hence, there are 6 different tripeptides that can be formed when one isoleucine, one alanine, and one glycine react. Therefore, the correct answer is 6, which is not among the provided options.

6 different tripeptides can be formed when one isoleucine, one alanine, and one glycine react.

To determine the number of different tripeptides that can be formed when one isoleucine, one alanine, and one glycine react, we need to consider the possible arrangements of these amino acids.

The number of different arrangements can be calculated by multiplying the number of choices for each position. In this case, there are three positions to fill with three different amino acids.

For the first position, we have three choices: isoleucine, alanine, or glycine.

For the second position, we have two choices remaining since we've already used one amino acid.

For the third position, only one amino acid is left.

By multiplying these choices together, we get:

3 choices × 2 choices × 1 choice = 6 different tripeptides

Therefore, the correct option is 6.

The boiling point of 1.83 M \(Na_2SO_4\)(aq) assuming 100% association is:
btb = 100°C + ΔTb = 100°C + 9.38°C = 109.38°C

Assuming 100% association, we can calculate the freezing point and boiling point of 1.83 M\(Na_2SO_4\)(aq) as follows:

First, we need to determine the van't Hoff factor (i) for \(Na_2SO_4\). The van't Hoff factor is the number of particles that one mole of a substance will produce in solution. For \(Na_2SO_4\), the van't Hoff factor is 3 because each mole of\(Na_2SO_4\) produces three ions (2 Na+ and 1 \(SO_4^2^-\)).

Next, we can use the formula for calculating the freezing point depression:

Δ\(T_f\)= \(K_f\) × i × molality

where \(K_f\) is the freezing point depression constant (1.86 °C/m for water), i is the van't Hoff factor, and molality is the number of moles of solute per kilogram of solvent.

For 1.83 M \(Na_2SO_4\)(aq), the molality is calculated as follows:

molality = (1.83 mol Na2SO4 / 0.1 kg H2O) / i
molality = (1.83 mol / 0.1 kg) / 3
molality = 6.1 mol/kg

Substituting into the formula, we get:

Δ\(T_f\)= 1.86 °C/m × 3 × 6.1 mol/kg
Δ\(T_f\)= 34.0 °C

Therefore, the freezing point of 1.83 M \(Na_2SO_4\)(aq) assuming 100% association is:

f\(t_f\) = 0°C - Δ\(T_f\) = 0°C - 34.0°C = -34.0°C

To calculate the boiling point elevation, we use a similar formula:

Δ\(T_b = K_b\) × i × molality

where \(K_b\) is the boiling point elevation constant (0.512°C/m for water).

For 1.83 M \(Na_2SO_4\)(aq), the molality is still 6.1 mol/kg, so we get:

Δ\(T_b\) = 0.512°C/m × 3 × 6.1 mol/kg
Δ\(T_b\) = 9.38°C

Therefore, the boiling point of 1.83 M \(Na_2SO_4\)(aq) assuming 100% association is:

b\(t_b\) = 100°C + Δ\(T_b\) = 100°C + 9.38°C = 109.38°C
