Glycolysis is the process by which energy is harvested from glucose by living things. Several of the reactions of glycolysis are

thermodynamically unfavorable (nonspontaneous), but proceed when they are coupled with other reactions. Which of these reactions is(are) unfavorable? Select all that apply.
(A) P1 + Glucose → Glucose-6-phosphate + H2O ΔG⁰= 3.30 kcal/mol
(B) P1 + Fructose-6-phosphate → Fructose-1.6-biphosphate + H2O ΔG⁰=3.9 kcal/mol
(C) ATP + H2O → ADP + P1 ΔG⁰=-7.30 kcal/mol

Answer:

Reaction A and B are unfavorable.

Explanation:

Gibbs free energy is an energy which that can be use to convert into useful work.

ΔG°=ΔH°-TΔS°

ΔG°= Gibbs free energy

ΔH° =  enthalpy of reaction

T = temperature of eh reaction

ΔS° = Entropy change

  • If the Gibbs  free energy of the reaction is positive than the reaction will be non spontaneous and the chemical reaction will be not feasible.
  • If the Gibbs  free energy of the reaction is negative than the reaction will be spontaneous and the chemical reaction will be feasible .

According to given information in the question:

Reaction A and B are non spontaneous as their Gibbs free energy value is positive.hence both are unfavorable.

six different aqueous solutions are represented in the beakers below, and there total volumes are noted. (a) which solution has
wolverine [178]

The molarity of the solutions are as follows:

  • solution B has the highest molarity
  • solutions A, D and F have the same molarity
  • solutions A and C are mixed together have a lower molarity than B
  • solution F and D will have the same molarity
  • Volume of water required to be evaporated is 8.3 mL

<h3>What is molarity of a solution?</h3>

The molarity of a solution is the amount in moles of a substance present in a given volume of solution.

From the image of the solution given:

  • solution B has the highest molarity
  • solutions A, D and F have the same molarity
  • when solutions A and C are mixed, the resulting solution have a lower molarity than B
  • solution F and D will have the same molarity after 75 mL and 50 mL of water are added to each respectively
  • the molarity of B is 12/50 = 4/16.7. Volume of water required to be evaporated = 25 - 16.7 = 8.3 mL

Therefore, the molarity of the solutions depends on the moles of substance present per given volume of solution.

What will most likely happen when stress is applied to an equilibrium reaction? The system will not respond to the stress. The s
steposvetlana [31]

Answer:

The system will change its concentration to shift to a new equilibrium position.

Explanation:

For example  in the Haber Process

N2  +  3H2  ⇄  2NH3

If the pressure is increased the  process will move to the right - to have more NH3 and less of the nitrogen and hydrogen.

Provide at least three indicators of a chemical change that are present in burning a piece of paper.
Pie

Answer:

Some chemical indicators perceived while a piece of paper is burning are:

Production of an Odor: there is a smell of burnt paper

Change in Temperature:  combustion is a highly exothermic reaction , so the temperature increase

Change in Color: paper changes to ashes as the burning process occurs

If I remove the table from under the book, what will happen to the book? Think about Newton’s second law of motion. Is there an
tiny-mole [99]

Newton’s second law of motion is a dot product of mass and acceleration, if you remove the table from, under the book, gravity will act on the book and pull it downwards to the centre of the earth

Newton's Second law of motion states that "<em>the </em><em>acceleration</em><em> of an object depends upon </em><em>two</em><em> </em><em>variables</em><em> – the net force acting on the object and the mass of the object.</em>"

In our case the mass of the book and the force of gravity
