Answer:
n = 7.86 mol
Explanation:
This question can be solved using the ideal gas law of PV = nRT.
Temperature must be in K, so we will convert 22.5C to 295 K ( Kelvin = C + 273).
R is the ideal gas constant of 0.0821.
(2.24atm)(85.0L) = n(0.0821)(295K)
Isolate n to get:
n = (2.24atm)(85.0L)/(0.0821)(295K)
n = 7.86 mol

Answer:
d. increases PFK activity, decreases FBPase activity
Explanation:
Fructose-2,6-bisphophate is formed by the phosphorylation of fructose-6-phosphate catalyzed by phosphofructokinase-2, PFK-2.
Fructose-2,6-bisphophate functions as an allosteric effector of the enzymes phosphofructokinase-1, PFK-1 and fructose-1,6-bisphosphatase, FBPase.
Fructose-2,6-bisphophate has opposite effects on the enzymes, PFK-1 and FBPase. When it binds to the allosteric site of the enzyme, PFK-1, it increases the enzymes's activity by increasing its affinity for its substrate fructose-6-phosphate and reduces its affinity for its allosteric inhibitors ATP and citrate. However, when it binds to FBPase, it reduces its activity by reducing its affinity for glucose, its substrate
Answer: Free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
Explanation:
It is known that free energy change is represented by the symbol . Free-energy helps in determining the direction of a chemical reaction like if it is taking place in forward or backward reaction.
For a spontaneous reaction, the standard free-energy change is negative in nature and the reaction will proceed in forward direction.
Thus, we can conclude that free-energy change of a reaction is a measure of the direction in which a net reaction occurs.
When an atom gains or donates electrons to form an ion is called ionization. Hydrochloric acid with water and carbon dioxide with water are the ionization reaction.
<h3>What are Ionization reactions?</h3>
In ionization reactions, the chemical species undergo changes to gain or lose electrons to acquire charge.
The reaction between hydrochloric acid and water to yield hydronium ion and chloride ion, and the reaction between carbon dioxide and water to yield hydronium ion and bicarbonate ion is the example of ionization as electrons are donated and gained by the species.
Therefore, the ionization reaction results in the gain or loss of electrons.
