Explanation:
(a) Equilibrium constant expression is ratio of concentrations of products over reactants each raised to their power of stoichiometric coefficients.
For example consider an equilibrium which is:
The expression is:
![K_c=\frac {[C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%20%7B%5BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D)
(b) Equilibrium constant of the chemical reaction is value of the reaction quotient of the reaction at the stage of chemical equilibrium which is a state that is approached by the dynamic chemical system at which the composition of the reactant and the product has no measurable tendency towards the change.
(c) Absorbance is the measure of capacity of the substance to absorb the light of a specific wavelength. Absorbance is equal to the logarithm of reciprocal of transmittance.
(d) The Beer's law relates attenuation of the light to properties of material through which light is travelling.
The expression for the law is:
A = ε × l× c
Where,
A is the absorbance
ε is molar absorptivity coefficient
l is the path length
c is the concentration.
Mass of Copper : 63.5 g
<h3>Further explanation</h3>
Given
Reaction
Cu(s)+2AgNO₃ (aq) ⇒Cu(NO₃)₂ (aq)+2Ag(s)
Required
Mass of Copper
Solution
mol of Silver nitrate :
= M x V
= 2 mol/L x 0.5 L
= 1
From the equation, mol ratio of Cu : AgNO₃ = 1 : 2, so mol Cu = 1
Mass of Cu(Ar=63.5 g/mol) :
= mol x Ar
= 1 x 63.5
= 63.5 g
The ability for gas to mix with other or multiple substances is diffusion
Answer:
Tc
Explanation:
You just have to follow the rows with the exponents. Just remember that when we get to d, the number in the front is a period lower. Hope this helps!
The energy input into the icemaker is used to drive the cooling system. The equipment has a radiant that requires to be run by electricity. Liquid ammonia in the radiant tubes of the icemaker pick up heat from the water and evaporate. As the ammonia evaporates and moves to the radiator, the action of the fan cause it to lose heat to the environment. The ammonia cools and becomes liquid and moves back to collect more hest from teh water. This cycle continues unilt the water turns to ice.
