In ____________ reactions, certain molecules are broken down; in the process they release energy which is captured when high-ene

rgy molecules (such as NADH and ATP) are formed. The breakdown of these molecules can then be coupled to thermodynamically unfavorable processes such as ____________ reactions or pumping hydrogen ions from ____________ to ____________ concentration areas.

Answer:

Exergonic ,Endergonic,low concentration area,high

Explanation:

In exergonic reaction,certain molecules are broken down;in the process they release energy which is captured when high energy molecules(such as ATP and NADH) are formed.

                          The breakdown of these molecules can be coupled to thermodynamically unfavorable processes such as Endergonic reactions or pumping og hydrogen ion from low concentration areas to high concentration areas.

C. 49.8 grams of ki is dissolved in enough water to make 1.00 l of solution. what is the molarity?
taurus [48]

Hey There!:


Molar Mass KI => 166.003 g/mol


* number of moles:


n = mass of solute / molar mass


n = 49.8 / 166.003


n = 0.3 moles KI


Therefore:


M = n / V


M = 0.3 / 1.00


M = 0.3 mol/L


hope this helps!

Calculate the ΔG°rxn using the following information at 298K. 2 HNO3(aq) + NO(g) → 3 NO2(g) + H2O(l) ΔG°rxn = ? ΔH°f (kJ/mol) -2
Mkey [24]

Answer:

ΔG°rxn = +50.8 kJ/mol

Explanation:

It is possible to obtain ΔG°rxn of a reaction at certain temperature from ΔH°rxn and S°rxn, thus:

<em>ΔG°rxn = ΔH°rxn - T×S°rxn (1)</em>

In the reaction:

2 HNO3(aq) + NO(g) → 3 NO2(g) + H2O(l)

ΔH°rxn = 3×ΔHfNO2 + ΔHfH2O - (2×ΔHfHNO3 + ΔHfNO)

ΔH°rxn = 3×33.2kJ/mol + (-285.8kJ/mol) - (2×-207.0kJ/mol + 91.3kJ/mol)}

ΔH°rxn = 136.5kJ/mol

And S°:

S°rxn = 3×S°NO2 + S°H2O - (2×S°HNO3 + S°NO)

ΔH°rxn = 3×0.2401kJ/molK + (0.0700kJ/molK) - (2×0.146kJ/molK + 0.2108kJ/molK)

ΔH°rxn = 0.2875kJ/molK

And replacing in (1) at 298K:

ΔG°rxn = 136.5kJ/mol - 298K×0.2875kJ/molK

<em>ΔG°rxn = +50.8 kJ/mol</em>

If chemical bonds didn’t
hram777 [196]

All of the above answers are true right answer is option D

because, no bond no molecule no interaction no life,

no bond= only element will exist

Energy would not exist coz energy consumption and excretion takes place during bond formation and bond breaking process!

Plz answer thx<br><br><br> ​How many moles are in 2.5 x 10^18 grams of water?
alex41 [277]

Answer:

1.39\times 10^{17} moles of water in 2.5\times 10^{18} g of water.

Explanation:

Mass of water = m = 2.5\times 10^{18} g

Molar mass of water = M = 18 g/mol

Moles = n = \frac{m}{M}

n=\frac{2.5\times 10^{18} g}{18 g/mol}=1.39\times 10^{17} moles

So, there are 1.39\times 10^{17} moles of water in 2.5\times 10^{18} g of water.
