Which two factors must be equal when a chemical reaction reaches equilibrium?

1 answer:

3 0

The correct answer is the statement in option 3. Chemical equilibrium is achieved when both the reactants and the products are in concentrations that has no further tendency to change even as time goes to infinity. This happens when the forward reaction rate is the same as the reverse reaction rate.

Which of the following statements characterizes nuclear fission?

san4es73 [151]

Answer: C) the splitting of a nucleus released a large burst of energy

Explanation:

nuclear fission occurs when an isotope (usually unstable) is hit with particles such as neutrons and splits, resulting in an extreme burst of energy.

for instance, the atomic bombs developed by the U.S. during WWII were products of nuclear fission in which plutonium-239 and uranium-235 were struck by a neutron that hit either nucleus of either isotope. The result was the neclus split into fragments that released huge amounts of energy snd the fission process became self-sustaining as neutrons produced by the splitting nucleus hit other nuclei and produce more fission, causing a chain reaction.
