Answer 2

Why does the chemical reaction seen here obey the law of conservation of matter?

Answer:

• Because there are the same number of atoms of each element shown on both sides

Explanation

• As in chemical reactions, atoms bonds are break and new bonds are formed. As new substance are formed but overall they have same elements, no new elements come from outside or go to outside. In other words , rearrangement of atoms take place but number of atoms remained same.

                            NaOH + HCl -----> NaCl + H2O

• As in above reaction there are the same number of atoms of each element shown on both sides .
