Answer:

nitrite ion is NO2- and nitrate ion is NO3-

Explanation:

The nitrite ion has two oxygen atoms and one nitrogen atom while nitrate ion has three oxygen atoms and one nitrogen atom. They are both univalent negative anions that form compounds with metallic cations as shown below;

Na+ + NO3- ⇒ NaNO3 (sodium nitrate)

Na+ + NO2- ⇒ NaNO2 (sodium nitrite)

Ca2+ + NO3- ⇒ Ca(NO3)2 (calcium nitrate)

Ca2+ + NO2- ⇒ Ca(NO2)2 (calcium nitrite)

You can deduce from the above ionic equations that nitrate ion is NO3- while nitrite ion is NO2-.

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:

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

What is the mole, and why is it useful in chemistry?

Snowcat [4.5K]

Answer:The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.
