Question

NEED THE ANSWER !!! NOW i have like an hour

Answer 1

Answer No 1:

The chemical model that is flawed is:

4 C2 + S8 → 4 CS2

In this reaction, there are more number of carbon atoms in the reactants but lesser number of cabon atoms in the products. For a reaction to be balanced, there should be the same number  of atoms in the reactants and products. Hence, option A does not represent a balanced equation.

Answer No 2:

The correct option is B) The model shows an unbalanced number of carbon atoms.

Consider the equation:

4 C2 + S8 → 4 CS2

In the reactants side of the equation, there are 8 atoms of carbon. In the products side there are only four carbon atoms. This shows that this equation in not balanced because of the carbon atoms.

The number of sulfur atoms remains same before the reaction and after the reaction. There are eight sulfur atoms in the reactants as well as products.
