The reaction converting glycerol to glycerol-3-phosphate is energetically unfavorable by 9.2 kJ. The reaction of ATP with water

to yield ADP, hydrogen phosphate ion, and hydrogen ion is energetically favorable by 30.5 kJ. These reactions are coupled so that the overall process is energetically favorable. What is ΔG for the overall process?

Answer:

ΔG for overall reaction :  -21.3 kJ

Explanation:

Reaction of the conversion of glycerol to glycerol-3-phosphate is unfavorable and thus is coupled with second reaction that involves the conversion of ATP to ADP which is highly energetically favorable.

Reaction 1:  Glycerol + HPO₄²⁻ ⇒ Glycerol-3-phosphate + water

Reaction 2:             ATP  + H₂O ⇒ ADP + HPO₄²⁻ + H⁺

ΔG for reaction 1 : 9.2 kJ (non-spontaneous : Positive value)

ΔG for reaction 2 : -30.5 kJ (spontaneous : Negative value)

The overall coupled reaction is:

<u>Glycerol + ATP ⇒ Glycerol-3-phosphate + ADP + H⁺</u>

<u>ΔG for overall reaction : 9.2 kJ + (-30.5 kJ) = -21.3 kJ</u>

negative sign signifies that the overall reaction is spontaneous.

Boron carbonate decomposes into boron oxide and carbon dioxide. How many moles of CO2
Paul [167]
<h3>Answer:</h3>

15 moles

<h3>Explanation:</h3>

The decomposition of boron carbonate is given by the equation;

B₂(CO₃)₃(s) → B₂O₃(s) + 3CO₂(g)

Moles of boron carbonate decomposed is 5.0 mol

To find the moles of CO₂ produced we are going to use the mole ratio.

Mole ratio of B₂(CO₃)₃ to CO₂ is 1 : 3

Therefore;

Moles of CO₂ = Moles of B₂(CO₃)₃ × 3

                      = 15 mol

Therefore, 15 moles of CO₂ will be produced

Magnesium (24.48g) reacts with hydrochloric acid (xg) to produce hydrogen gas (2.04g) and magnesium chloride (96.90g). How much
andriy [413]

Answer:

Mass = 73.73 g

Explanation:

Given data:

Mass of Mg used = 24.48 g

Mass of HCl used = ?

Mass of hydrogen gas produced = 2.04 g

Mass of Magnesium chloride produced = 96.90 g

Solution:

Chemical equation:

Mg + 2HCl   →    MgCl₂ + H₂

Number of moles of Mg:

Number of moles = mass/ molar mass

Number of moles = 24.48 g/ 24.305 g/mol

Number of moles = 1.01 mol

Now we will compare the moles of Mg with HCl from balance chemical equation.

                              Mg             :            HCl

                               1                ;               2

                            1.01              :           2/1× 1.01 = 2.02 mol

Mass of HCl react:

Mass = number  of moles × molar mass

Mass =  2.02 ×  36.5 g/mol

Mass = 73.73 g
