10th Class Physical Science Project Works in Chapter 2. Chemical Reactions and Equations

These are the important physical science project works will be given to the Students who are studying 10th Class in both Andhra pradesh & telangana States. These Project works increase the creative thinking in the Students which is helps allot in New Evaluation System C.C.E (Continuous Comprehensive Evaluation System) introduced by SCERT.

Write the word equations for each of the following chemical reactions:
10th Class Physical Science Project work - 1:
When dissolved beryllium chloride reacts with dissolved silver nitrate in water, aqueous
beryllium nitrate and silver chloride powder are made.

10th Class Physical Science Project work - 2:
When dissolved sodium hydroxide reacts with sulfuric acid (H2SO4), aqueous sodium
sulfate, water, and heat are formed.


10th Class Physical Science Project work - 3:
When fluorine gas is put into contact with calcium metal at high temperatures, calcium
fluoride powder is created in an exothermic reaction.


10th Class Physical Science Project work - 4:
When sodium metal reacts with iron (II) chloride, iron metal and sodium chloride are
formed.
