Troposphere is the highest layer of the atmosphere and touches space

Startophere is where stratus clouds form up high in the sky

The Mesosphere is the third layer you need to know and it’s low density ...yo?

Thermosphere we’re getting closer and closer to earth

Exoshpere were airplanes are high, buckle up it’s time to fly

hat is the pressure of CO(g) in equilibrium with the CO2(g) and O2(g) in the atmosphere at 25 ????C? The partial pressure of O2(

Lubov Fominskaja [6]

Answer:

The partial pressure of CO is 5.54x10⁻⁴⁹atm. You shouldn't worry because it is very low pressure

Explanation:

First, the balanced reaction is:

CO + 1/2O₂ → CO₂

The energies of formation are:

ΔG(CO)=-137.168kJ/mol

ΔG(O₂)=0

ΔG(CO₂)=-394.359kJ/mol

The energy of the reaction is:

$delta-G_{reaction} =delta-G_{CO_{2} } -(delta-G_{CO} +1/2delta-G_{O_{2} } )\\delta-G_{reaction}=-394.359-(-137.168+0)=-257.191kJ/mol$

The expression for calculate the partial pressure of CO is:

$p_{CO} =\frac{p_{CO2} }{p_{O_{2} }^{1/2}*exp^{-\frac{delta-G}{RT} } } \\p_{CO}=\frac{3x10^{-4} }{0.2^{1/2}*exp(-\frac{-257.191*1000}{8.314*298} ) } \\p_{CO}=5.54x10^{-49} atm$

levacccp [35]

Acetylsalicylic acid (ASA) or commonly known as aspirin is used as pain reliever, treatment for fever and inflammation. The type of bond that aspirin have is covalent bond. Covalent bond is when atoms share their electrons. Aspirin is made up of carbon, hydrogen and oxygen with a formula of C9H8O4.
