The answer is
option D "electron-cloud model." A electron-cloud model includes: includes positive charge, contains electrons, explains the photoelectric effect, suggests the probable location of electrons. It was also invented by Erwin Schrödinger.
Hope this helps!
Answer:
The rate of the forward reaction and the rate of the reverse reaction are equal
The concentrations of the reactants and products no longer change.
Explanation:
The equilibrium state is a state of rest or motion of chemical system.
These are some of the condition for dynamic equilibrium of a system:
the systems must be involved in reversible chemical reactions.
the rate of forward reaction is equal to that of the reverse process.
the system offers no resistance to any change in any of the factors.
there is no change in concentration of each of the species in equilibrium with respect to time.
We can see that a system in equilibrium clearly identifies with the chosen options.
I depends on the height of the other side of the cart. If it was lower, 400 N. If Higher, at least 600 N.
