Question

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

a. because there are the same number of atoms of each element shown on both sides
b. because they both start and end with diatomic (two-atomed) molecules
c. because they both start and end with the same types of particles
d. because they both start and end with two sets of particles eliminate

Answer 1

The chemical reaction seen here obey the law of conservation of matter because there are the same number of atoms of each element shown on both sides. The answer is A. Thank you for posting your question here. I hope it helps. 

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

Step-by-step 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 .
