For the following redox reactions, identify the species being oxidized, the species being reduced, the oxidizing agent, and the reducing agent:
17) Ni + F2 --> NiF2
18) Fe(NO3)2 + Al --> Fe + Al(NO3)3
19) Li + H2O --> LiOH + H2

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.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
