Sulfur dioxide burns in oxygen to form sulfur trioxide. How many moles of O2 would react with 2.2 x 10^20 molecules of SO2?

they are made of gases.

they have a spherical shape.

they make energy through fusion.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
