Mixtures and compounds are alike in the following ways:

1. Both mixture and compound contains two or more substances.

2. Both mixture and compound can be separated.

3. Both mixture and compound have physical properties.

Mixtures and compounds are different in the following ways:

1. A mixture contains two or more substances that are not chemically combined together while a compound contains two or more substances chemically combined together.

2. A mixture can be separated by physical methods while a compound can only be separated by chemical methods.

3. Mixtures can not be represented using a chemical formula. Compounds can be represented by chemical formula.

4. Examples of mixtures include: milk, kerosene in water etc. Examples of compounds include water, sodium chloride etc

Both can be separated.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
