Which of the following equations illustrates the law of conservation of matter?
a. 2na + cl2 nacl
b. 2na + cl2 2nacl
c. 2na + 2cl2 2nacl
d. na + cl2 2nacl

The correct answer is option (B).

Explanation:

Law of conservation of mass: 'In a chemical reaction, mass neither be created nor be destroyed'

In the balance chemical equation,total mass of the reactants is equal to the total mass of the products.

A.

117 g/mol  ≠ 58.5 g/mol

Law of Conservation of Mass not followed.

B.

117 g/mol  =  117 g/mol

Law of Conservation of Mass is followed.

C.

188 g/mol  ≠ 117 g/mol

Law of Conservation of Mass not followed.

D.

94 g/mol  ≠ 117 g/mol

Law of Conservation of Mass not followed.

Hence, the correct answer is option (B).

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

thermal energy is the answer
