Which is more harmful to the environment, NO2 or NO2-?
NO2 is more harmful to the environment than NO2-.
What is the pH of a 0.020 M nitric acid solution?
HNO2 ==> H+ + NO2^-Ka = 4x10^-4 = [H+][NO2^-]/[HNO2] 4x10^-4 = (x)(x)/0.100 x^2 = 4x10^-5 x = 6.32x10^-3 = [H+] pH = -log 6.32x10^-3 pH = 2.2
What is the conjugate base of hno2?
The conjugate base of HNO2 is NO2-. When HNO2 loses a proton, it forms its conjugate base, nitrite ion (NO2-).
What is the difference between NO2 plus and NO2?
NO2 plus (NO2+) is a cationic species with a positive charge, while NO2 is a neutral molecule. NO2 is a brown gas at room temperature, whereas NO2+ is a highly reactive and unstable species that is rarely encountered independently.
What is the name of NO2 -1?
The name of NO2- is nitrite.
What is the pH of a 0.35 M solution of NaNO2 in water KB for NO2- 2.5 x 10-11?
NaNO2 yields NO2 - + Na+ The salt NaNO2 completely ionizes, producing 0.35M [NO2-] and 0.35 [Na+] ions. NO2- is the conjegate base of the weak acid HNO2. You have to write a balanced equation for the reation at equilibrium. After you have done so, you need to set up an ICE (Initial, change, equilibrium) table, experssing the equilibrium concentrations of all species in terms of initial concentrations and a single unknown x, that represenst the change in concentraion: NO2 - + H2O yields HNO2 + OH- ---- Initial 0.35 0.00 0.00 Change -x +x +x ---- Equil. 0.35-x x x Know we use the equilibrium equation: Kb = [HNO2][OH-]/[NO2 - ] (2.5 x 10-11) = x2/ 0.35 - x (in this case we can omitt the x that is subtracted from the 0.35 concentration because the Kb value is so small and will not affect the value) So, 2.5 x 10-11 = x2/0.35 x = [OH-] = 2.96 x 10-6 Now that we have solved for the OH- concentration, we can solve for the pOH and then use that to solve for the pH. pOH = -log[OH-] pOH = -log[2.96 x 10-6] pOH = 5.53 pH + pOH = 14 pH = 14 - pOH pH= 14 - 5.53 pH= 8.47 ----
What chemical component in air causes the pH of rain lower than neutral?
These are oxides which can form acids: NO2, SO2, CO2.
Which is more harmful to the environment, NO2 or NO2-?
NO2 is more harmful to the environment than NO2-.
What is the Molecular formula for NO2?
NO2 is the molecular formula for NO2.
How NH4 NO2 NO3 effect pH in water?
When ammonium nitrite (NH4NO2) dissolves in water, it forms nitrite (NO2-) ions and ammonium (NH4+) ions, which can be slightly acidic due to the release of hydrogen ions (H+). On the other hand, nitrate (NO3-) ions from ammonium nitrate (NH4NO3) do not have a significant impact on water pH as they are neutral. Overall, the net effect on water pH will depend on the relative amounts and concentrations of these ions present.
What is the pH of a 0.020 M nitric acid solution?
HNO2 ==> H+ + NO2^-Ka = 4x10^-4 = [H+][NO2^-]/[HNO2] 4x10^-4 = (x)(x)/0.100 x^2 = 4x10^-5 x = 6.32x10^-3 = [H+] pH = -log 6.32x10^-3 pH = 2.2
Is NO2 bromine?
No. NO2 Is Nitrogen Dioxide.

How many moles of molecules are in 25.5g of NO2?
Determine the molar mass of NO2 using the subscripts in the formula and the atomic weights in grams from the periodic table. 1 mole NO2 = (1 x 14.0067g N) + (2 x 15.9994g O) = 46.0055g NO2 Calculate the moles NO2 by dividing the given mass by the molar mass. 25.5g NO2 x (1mol NO2/46.0055g NO2) = 0.554mol NO2
Will pH fluctuate in water?
Yes, because water absorb from atmosphere gases wit acidic potential (CO2, NO2, SO2, etc.) and become more acidic.
What does NO2 stand for?
NO2 is the chemical formula for nitrous oxide.
