g Which of the following is TRUE for a system that is in dynamic equilibrium? Which of the following is TRUE for a system that i

Firdavs [7]

Answer:

none of the above

Explanation:

A system is said to have attained dynamic equilibrium when the forward and reverse reactions proceed at the same rate. That is;

Rate of forward reaction = Rate of reverse reaction

The implication of this is that the concentrations of reactants and products remain constant when dynamic equilibrium is attained in a system. This does not mean that the reactant and product concentrations become equal; it rather means that their concentrations do not significantly change once dynamic equilibrium has been attained.

The chemical formula for ethanol is C2H601.How many total atoms are in 30 molecules of ethanol?

12345 [234]

There are two carbon atoms in every ethanol molecule, so there would be 60 carbons all together.

I hope this helped you!
