Measure 25cm³ of the ammonia provided and transfer it into a conical flask at 50cm³ of 0.1mol of sodium hydroxide to the ammonia in the conical flask add three drops of phenolphthalein filled the burette provided with 0.1mol of HCl solution and titrate it against the excess HCl in the conical flask. repeat the titration two or three times following the same procedure. calculate concentration of the ammonia in mol/dm³. Balance the equation for the reaction.​

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.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
