Molar mass HCl = 36.5 g/mol

number of moles:

mass of solute / molar mass:

9.63 / 36.5 => 0.263 moles

Volume = 1.5 L

M = n / V

M = 0.263 / 1.5

M = 0.1753 mol/L

Answer : The molarity of the solution is, 0.175 mole/L

Solution : Given,

Mass of HCl = 9.63 g

Molar mass of HCl = 36.5 g/mole

Volume of solution = 1.5 L

Molarity : It is defined as the number of moles of solute present in one liter of the solution.

Formula used :

Molarity=\frac{\text{moles of solute}}{\text{Volume of solution in liters}}

or,

Molarity=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution in liters}}

Now put all the given values in this formula, we get the molarity of the solution.

Molarity=\frac{9.63g}{36.5g/mole\times 1.5L}=0.175mole/L

Therefore, the molarity of the solution is, 0.175 mole/L

Phosphofructokinase catalyzes the phosphorylation of fructose 6‑phosphate to fructose 1,6‑bisphosphate in glycolysis. Fructose 1
umka2103 [35]

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

A molecule with 14 total electrons and 12 total protons
Snowcat [4.5K]

Answer:

Explanation:

Tenochtitlan was located on a swampy island in Lake Texcoco in what is today south central Mexico. The Aztecs were able to settle there because no one else wanted the land. At first, it wasn't a great place to start a city, but soon the Aztecs built up islands where they could grow crops. The water also worked as a natural defense against attacks from other cities.
