4) How many moles are in 1.18 g of NO2?
Molar mass NO2 = 46.0 g/mole1.18 g NO2 x 1 mol NO2/46.0 g = 0.0257 moles NO2 (to 3 significant figures)
How many moles are in 19 g of NO2?
0.41
Equation to show NO2 acts as a reducing agent and oxidising agent?
NO2(g)+SO2(g)-->NO(g)+SO3(g) here NO2 act as a oxidising agent
What is the equilibrium constant for the reaction so2 (g) no2 (g) so3 (g) no (g)?
SO2(g) + NO2(g) ==> SO3(g) + NO(g)Keq = [SO3][NO]/[SO2][NO2] Without knowing concentrations, one cannot calculate the actual value of Keq.
How would the equilibrium change if NO2 were added to SO2(g) NO2(g) NO(g) SO3(g) heat?
The amount of NO2 and SO2 eould

NO2(g)+SO2(g)-->NO(g)+SO3(g) here NO2 act as a oxidising agent
What is the equilibrium constant for the reaction so2 (g) no2 (g) so3 (g) no (g)?
SO2(g) + NO2(g) ==> SO3(g) + NO(g)Keq = [SO3][NO]/[SO2][NO2] Without knowing concentrations, one cannot calculate the actual value of Keq.
How many moles are in 25.6 g of NO2?
Molecular mass of nitrogen dioxide, NO2 = 14.0+2(16) = 46.0Amount of NO2 = 25.6/46.0 = 0.557molThere are 0.557 moles of NO2 in a 25.6g sample.
How would the equilibrium change if NO2 were added to SO2(g) NO2(g) NO(g) SO3(g) heat?
