When writing a chemical reaction equation, what does the arrow ( ---> ) represent?

A. the reactants are making the products
B. the direction of the chemical equation
C. the chemical reaction cannot be reversed
D. all of the above

A

Explanation:

I think

The condition or progress of a reaction is represented by reaction arrows. The chemical reaction arrow is a single straight arrow that points from the reactant(s) to the product(s) and by-products, as well as side products.

I think this should help you find the answer more easy!

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

it is stable as it is in group 0 which have full outer shells of electrons
