Answer:
2
Explanation:
There are at least 2 atoms in a molecule
The words are:
True, false, weak electrolyte, strong electrolyte, non-electrolyte, does not, does, H+ is, OH- is, no ions are, acidic, basic, neutral.
HCN is a weak electrolyte that partially ionizes in water and forms an acidic solution as H+ ions are formed, while acetone is a non-electrolyte that does not form ions in water and the resulting solution is neutral.
It is true that when hydrogen cyanide, HCN, dissolves in water, the solution is weakly conducting and acidic in nature. This is because hydrogen cyanide, HCN, is a weak electrolyte that only partially ionizes in water, and hence does support the movement of charge, albeit to a lesser extent than a strong electrolyte. In addition, since H+ ions are specifically formed from the ionization of HCN in water, the solution is acidic.
It is false that when acetone, CH3COCH3, is dissolved in water a conducting solution results. This is because acetone, CH3COCH3, is a non-electrolyte. It does not ionize in water, and therefore does not support the movement of charge. As such, no ions are formed when acetone is dissolved in water and the solution remains neutral.

The colloid particles are more solid.
The colloid particles are smaller.
The colloid particles are larger.
Answer: The correct option is that the colloid particles are smaller.
Explanation: There are 3 types of solutions:
1) True solutions: These are the solutions in which the size of the particles are less than 1nm. These are considered as homogeneous mixtures.
2) Colloids: These solutions are the solutions in which the size of the particles lie in the range of 100nm to 1nm. These are assumed to be homogeneous mixtures but actually are heterogeneous mixtures.
3) Suspension: These solutions are the solutions in which the size of the particles are greater than 100 nm. These are considered as homogeneous mixtures.
The particles which are dispersed in a colloid have smaller particles than the particles which are dispersed in a suspension.
Answer:
some bonds are broken and new ones are formed. Now you are ready to learn more about those bonds. Chemical bonds are attractions between atoms. They are simply attractive forces (between the + nucleus of one atom and the - electrons of a neighboring atom) that hold groups of atoms together and make them function as a unit.
