1) 1.9g MgY2 is dissolved in 100cm^3 of water to produce a solution with the molarity of 0.2 moldm^-3. What is the relative atomic mass of Y? [Relative atomic mass : Mg =24]​

its going to be mutualism cuz they both benefit from the relationship.

the answer is c i took the test

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
