Help me timed test Manganese-56 has a half life of 2.6 hrs. How many g of a 13.3 g sample will remain after 8 half lives? Keep 2 sig figs, and be sure to use the correct units in your answer.

since electrons are negative the answer is neagtaive

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 correct answer would be b) volume versus temperature, because they are also directly proportional.
