Which of the following are examples of physical properties of ethanol? Select all that apply. The boiling point is 78.37°C

It is a clear, colorless liquid

It is flammable

It is a liquid at room temperature

c. electrical charges of ionic bonds.

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
