How much heat is required to raise the temperature of 45.0g of Iron (Fe) from 15.5°C to 87.5°C? (C​ p​for Iron= 0.4494 J/g°C)

i do not get it   at all

i think its 100.

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
