Answer 2

Answer:

How many examples you want dear.......

is this enough....

Explanation:

1. Na2 + H2O `->` 2NaOH

Here sodium oxide is combined with water gives sodium hydroxide.

2. 4Li + O2 `->` 2Li2O

Here lithium is combined with oxygen to form lithium oxide.

3. 2Mg + O2 `->` 2 MgO

Here magnesium is combined with oxygen to form magnesium oxide.

4. H2 + Cl2 `->` 2 HCL

Here hydrogen is combined with chlorine to form hydrochloride.

5. NH3 + HCl `->` NH4Cl

Here colorless ammonia is added to colorless hydrogen chloride gives ammonia chloride.

6. 2H2 + O2 `->` 2 H2O

Here hydrogen is burned in the air or oxygen produces water.

7. S + O2 `->` SO2

Here sulphur is burned in the air to produce sulphur dioxide.

8. Ba + F2 `->` Ba F2

Here barium metal and fluorine gas is combined to produce salt barium fluoride which is highly exothermic reaction.

9. MgO + CO2 `->` MgCO3

Here magnesium oxide is combined with carbon to produce magnesium carbon dioxide.

10. 2Al + 3Br `->` 2AlBr3

Here aluminum is combined with bromine which produces 3 + aluminum iron and 1+bromine iron.

Hope it helps you dear.......
