alex41 [277]

Answer:

there is no shift in the state

Explanation:

The correct answer is - There is no shift in the state.

Reason -

If K > Q, a reaction will proceed forward, converting reactants into products.  If K < Q, the reaction will proceed in the reverse direction, converting products into reactants.  If Q = K then the system is already at equilibrium.

where Q, is the reaction Quotient

What is the kinetic energy of a 478 kg object that is moving with a speed of 15m/s
AVprozaik [17]

Answer:Kinetic energy = (1/2)*mass*velocity^2

KE = (1/2)mv^2

KE = (1/2)(478)(15)^2

KE = 53775J

Explanation:

Kinetic energy = (1/2)*mass*velocity^2

KE = (1/2)mv^2

KE = (1/2)(478)(15)^2

KE = 53775J

When an electron of an atom returns from an excited state to the ground state, it emits energy in the form of a photon. How does
Andrej [43]
The change in energy level is equivalent to the energy of the released photon. This is related by Planck's equation:
E = hcf
The higher the energy change, the greater the frequency, f, of the photon.
