test on mixtures

1. 1a [blank_start]homogenous mixture[blank_end] is the same all through

   1. Ahomogenous mixture
   2. Bheterogenous mixture
2. 2a mixture is a combination of two or more substances [blank_start]physically[blank_end] combined.

   1. Achemicallly
   2. Bphysically
3. 3an example of a Homogeneous mixture is [blank_start]salt and water[blank_end]

   1. Asand and orange juice
   2. Boil and water
   3. Csalted water
4. 4a and b represent [blank_start]heterogeneous and Homogeneous[blank_end] types of mixtures

   

   1. AHomogeneous and heterogeneous
   2. Bheterogeneous and Homogeneous
   3. Cheterogeneous and immiscible
   4. Dimmiscible and Homogeneous
5. 5homogeneous mixtures [blank_start]where a solute dissolves in solvent[blank_end] is called a solution .

   1. Awhere a solvent dissolves in solute
   2. Bwhere silt particles dissolve in water
   3. Cwhere a solute dissolves in solvent
   4. Dwhere oil particles dissolve in the sea
6. 6[blank_start]heterogeneous residue filter & filtrate[blank_end] are the labels a,b c and d of the diagram

   

   1. Aheterogeneous residue filter & filtrate
   2. Bheterogeneous filtrate filter & residue
   3. Chomogeneous filter filtrate & residue
   4. Dhomogeneous filter residue & filtrate
7. 7a suspension is a homogeneous mixture in which the solute particles remain dispersed in the mixture.

   1. AVerdadero
   2. BFalso
8. 8milk, smoke, foam. aerosol, emulsions -(mayonnaise) are examples of

   1. Aonly heterogeneous mixtures
   2. Bsolutions
   3. Ccolloids
   4. Donly heterogeneous suspensions
9. 9A suspension is a heterogeneous mixture in which particles do not dissolve, settle on standing and thus can be separated by simple filtration
   eg chalk and water.

   1. AVerdadero
   2. BFalso
10. 10colloids can be classed as a suspension but not all suspensions can be classed as a colloid

    1. AVerdadero
    2. BFalso
