- A colloid is a homogeneous mixtures of two phases.
- The dispersed phase and the dispersion medium.
- Water is the dispersion medium and oil is the dispersed phase.
They have the following properties:

1.915e23 Atoms
Explanation:
There are 6.02214076e23 is the mass of a mol in amu. Since the amu of lead is 207.2, and there is 65.89 grams of it, you can find that it creates approximately 1.914 atoms.
Answer:
Presence of impurities in the product.
Explanation:
Laboratory experience has shown that the percent yield obtained from a reaction may be greater than 100% if the product obtained from the reaction contains impurities that causes its mass to be greater than it actually would be if the product was pure.
A typical impurity that may be present in a product is the solvent used. This can be removed by evaporation of the solvent or by washing the product thoroughly.
Reaction of solid products with gases may also increase the percentage yield above 100%.
