Basic phyiscal and chemical properties are things like boiling point, melting point, solubility in water, conductivity, pH (acid, alkili/base or neutral).
The bonding type (ionic, covalent or polar covalent) can be extremely influential on the properties of a compound.
Ionic compounds have bonding between physically separate positive and negative ions. Covalent compounds involve sharing of electrons in bonds that keep atoms fixed in place.
If this is for an assignment and you don't know where to look, try looking in your course materials or data booklet in the section about ionic and covalent bonding, as it looks like that type of question. You may find there is a data table there listing the properties found in compounds according to their bonding type. This is certainly provided in Scottish Higher Chemistry.
All the best for the assignment!

Added to what the last person said sand is Silicon dioxide. (SiO2).
As people before have said looking in Wikipedia is a good place to start as the MSDS sheets. If you go to a chemical company website like Sigma Aldrich and put in the chemical name it will come up with a selection of different sizes and purities they sell. Select one and it will include information like the Molecular weight, pH range, Melting point solubility and so forth. It also has a link to the MSDS (material safety data sheet).
The one below is the one for salt, sodium chloride.

Chalk = calcium carbonate, which is also found in antacids
(Table) Salt = sodium chloride, which is delicious
Sand = could be quartz
Try finding the MSDS sheets on these chemicals

First as it is sublimate heat it until it evaporates Then you get salt and sand mixture . To separate the sand from salt you should add water to the mixture. Then using filter paper separate the sand from the salt solution . Heat the solution so that the water evaporates then you get salt This is how you separate the mixture

ammonium chloride - NH4Cl
- it sublimes based on NH4Cl (s) <=> NH3 (g) + HCl (g)
chalk - CaCO3 - limestone - reacts with acids to form CO2
salt - NaCl - makes food yummy!
sand - SiO2 - Giant macromolecular structure similar to that of diamond.

Hopefully these will get you started. Never use wikipedia as a single source. Although generally accurate, it is subject to error and vandalism.
