What mass of hydrogen is produced from the reaction of 50.0 g of Mg and 75.0 g of HCl? How much of the excess reagent is left over? Mg + 2HCl → MgCl2 + H2

i think its 100

i hope this !

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
