In determining the Hreaction for formation of MgO, why didn’t we directly burn the Mg metal in air and measure the heat produced?

so what is the problem with your lab report and whats the subject of the lab report? i will you

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

i believe the answer is three water molecules
