2Mg + 02 - 2Mgo a) If 6 moles of Mg reacts with 4 moles of O2, How many moles of MgO are formed?

b) If the actual yield of MgO is 100 g. What is the percentage yield of Mgo?

he would use the colour black

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
