This is the images below are models that represent the reactants and products of a chemical reaction. based on the models, was mass conserved in this chemical reaction? a. yes, because the number of each type of atom is the same in the products as it is in the reactants. b. yes, because the number of reactant molecules is the same as the number of product molecules. c. no, because the reactants are made up of different types of molecules than the products. d. no, because the purple atom formed two bonds in its reactant molecule and only one bond in its product molecule.

Answer : the correct option is, A

Explanation :

In the chemical reaction, some substances react together are called reactant and the substance are formed are called product.

From the given diagram, we conclude that the arrangement of molecules are different on both side.

On the reactant side, the purple molecules bonded with red and white molecule and the green molecule with white molecules. On the other hand i.e on product side, the red molecule bonded with two white molecule and purple molecule bonded with green molecules. The molecular arrangement are different on both side of the reaction mixture. But, the mass remains conserved.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

i think it is true since you can test the answer and can use observations to complete it.
