In a voltaic cell made of a Ag strip and an Al strip immersed in 1.0 M aqueous AgNO_3 and Al(NO_3)_3 solutions, respectively, wi

Water transitions to ice when temperatures drop too low, while it turns into gas when temperatures rise too high.
Conversely, ice transforms back into water when heated, remaining unchanged if temperatures are too low.
Furthermore, gas transitions to water when cooled and can freeze into ice if cooled further, continuing this cycle.
I hope this clarifies things.
 

Answer:

Unfavorable reactions include Reaction A and Reaction B.

Favorable coupled reactions: Reactions B with C and Reactions A with C.

Net energy change:

For Reactions B and C: -14.2 kJ/mol

For Reactions A and B: 30.1 kJ/mol

For Reactions A and C: -16.7 kJ/mol

Explanation:

A reaction is considered thermodynamically favorable (or spontaneous) if ΔG is less than 0. Thus, the unfavorable reactions where -ΔG is greater than 0 are:

Reaction A and Reaction B.

In coupling Reaction C with Reaction B and Reaction A, the following equation is obtained:

ATP + fructose-1,6-phosphate ⟶ ADP + fructose-1,6-bisphosphate

ΔG equals 16.3 minus 30.5, resulting in -14.2 kJ/mol.

For the reaction ATP + glucose ⟶ ADP + glucose-6-phosphate, ΔG equals 13.8 minus 30.5, yielding -16.7 kJ/mol.

Overall, the coupled reaction of A and B results in a change of free energy of:

ΔG = 13.8 plus 16.3, which equals 30.1 kJ/mol.

The reaction will yield 2 mol of H₂O. The balanced chemical equation for this process is: c3h8 (g) + 5o2 (g) → 3co2 (g) + 4h2o (g). Since 5 moles of O₂ create 4 moles of H₂O, 2.5 mol of O₂ will produce: 2.5 x 4/5 = 2 mol of H₂O.

The correct answer is option (D): CO₂, BCl₃, and Fe³⁺. Lewis theory defines an acid as a substance that can accept electron pairs, while a base donates electron pairs. a. It’s a Lewis acid as it accepts electron pairs. b. It isn't a Lewis acid since it does not accept electron pairs, but serves as a base by donating and accepting hydrogen ions. c. This qualifies as a Lewis acid as it accepts electron pairs due to having an incomplete octet and empty 2p orbitals. d. This is categorized as a Lewis acid as it accepts electron pairs. Therefore, the ions recognized as Lewis acids include CO₂, BCl₃, and Fe³⁺.
