How many joules of heat are absorbed to raise the temperature of 435 grams of iron (specific heat 0.444 J/gC at 1 atm from 25°C to 100.°C?

i would say b

explanation:

but i think i would need more information than that

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

the answer your looking for is c).
