The reaction p4 + 5o2 → p4o10 + 712 kcal is exothermic. true false

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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
