How many moles of 0.225 M CaOH2 are present in 0.350 L of solution?

Calculate the number of moles of solute (CaOH2)

M CaOH2)

(0.350 L ) =

mol CaOH2

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

i think it's letter a.
