Answer:
None of the conditions will favor either the forward reaction or backward reaction , hence the answer is D
Explanation:
- The principle of chemical Equilibrium is applied here, where the concentration of the reactants or the forward reaction is same as the concentration of the products or the backward reaction.
- The equilibrium constants is also involved here, K can be in terms of pressure (Kp) or concentration (Kc) hence equilibrium constant is the ration of the concentration of the products to the concentration of the reactants raised to the power of the coefficient of the reactants and products.
- Partial pressure , total pressure and the mole fraction relationship is also applied
- The step by step explanation is as shown in the attachment below.
Answer:
d. Electrons would be ejected and they would have greater kinetic energy than those ejected by yellow light.
Explanation:
A formula that describes the kinetic energy of an electron ejected when a surface is truck by light is:
- Ephoton = KineticEnergyElectron + Φ
As you see, the higher the energy of the photon striking the surface, the higher the kinetic energy of the ejected electron.
<em>Ultraviolet light has more energy than yellow light</em>, so it would cause<em> the ejected electron to have greater kinetic energy as well</em>.
Answer:
i dont understand ... whats the question?
Explanation:
I am taking a guess that you mean 5 M solution instead of 5m, there is a different because M means molarity while "m" means molality.
molarity (M)= moles/ Liters
you can use this formula to solve for the moles
moles= Molarity x liters
molarity= 5 M
liters= 500mL= 0.500 L
moles= 5 x 0.500= 2.5 moles
note: if you did mean molality, let me know so I can edit the answer but it is actually the same answer.
