At night, an equilibrium reaction between two different nitrogen compounds generates N2O5N2O5 in the atmosphere, as represented
kakasveta [241]

The breakdown of NO3 in the day leads to more consumption of N2O5 in the day hence its concentration is greater at night than in the day.

<h3>What is equilibrium constant?</h3>

The equilibrium constant is a number that shows how much reactants are converted to products in a reaction. It is often shown as capital letter K in English.

Given the situation described in the question, we know that the concentration of N205 will be higher at night, because the decomposition of NO3(g) in the daytime will result in an increase in the rate of consumption of N2O5(g) to reform NO3(g).

A voltaic cell is constructed from an Ni2+(aq)−Ni(s) half-cell and an Ag+(aq)−Ag(s) half-cell. The initial concentration of Ni2+
SCORPION-xisa [38]

Explanation:

For what I can see, is missing the concentration of [Ag+] in the half-cell. To calculate it:

Niquel half-cell

Oxidation reaction: Ni \longrightarrow Ni^{2+}+2 e^-

E=E^0 - \frac{R*T}{n*F}*ln(1/[Ni^{2+}])

Assuming T=298 K / R=8.314 J/mol K / F=96500 C

E=-0.23V - \frac{8.314*298}{2*96500}*ln(1/0.014M)

E=-0.285V

Silver half-cell

Reduction reaction: Ag^+ + e^- \longrightarrow Ag

E=E^0 - \frac{R*T}{n*F}*ln(1/[Ag+])

E_{cell}=E_{red} - E_{ox}

E_{red}=1.12 V + (-0.855V)=0.835V

Assuming T=298 K / R=8.314 J/mol K / F=96500 C

0.835V=0.8V - \frac{8.314*298}{1*96500}*ln(1/[Ag+])

[Ag+]=0.26 M

How are organelles connected to cell theory?
dsp73

Answer: bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

Explanation: An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.
