Semiconductors are made of the metalloids silicon and germanium
Wavelength of any wave can't be equal to the number with exponential of 23, otherwise, if you're focusing on visible light, and neglecting the exponential then your color would be: orange. [ Again, remember wavelengths can be in between 10 to 10^-14 ]
In short, Your Answer would be: Orange
Hope this helps!
Answer:
![[NO]=\frac{k_{-1}}{k_1} [N_2O_2]](https://tex.z-dn.net/?f=%5BNO%5D%3D%5Cfrac%7Bk_%7B-1%7D%7D%7Bk_1%7D%20%5BN_2O_2%5D)
Explanation:
Hello!
In this case, since the reaction may be assumed in chemical equilibrium, we can write up the rate law as shown below:
![r=-k_1[NO]+k_{-1}[N_2O_2]](https://tex.z-dn.net/?f=r%3D-k_1%5BNO%5D%2Bk_%7B-1%7D%5BN_2O_2%5D)
However, since the rate of reaction at equilibrium is zero, due to the fact that the concentrations remains the same, we can write:
![0=-k_1[NO]+k_{-1}[N_2O_2]](https://tex.z-dn.net/?f=0%3D-k_1%5BNO%5D%2Bk_%7B-1%7D%5BN_2O_2%5D)
Which can be also written as:
![k_1[NO]=k_{-1}[N_2O_2]](https://tex.z-dn.net/?f=k_1%5BNO%5D%3Dk_%7B-1%7D%5BN_2O_2%5D)
Then, we solve for the concentration of NO to obtain:
Best regards!
I think it's letter:
B.Coefficients are placed in front of the reactants and/or products
Answer:
A-A and B-B attractive forces contains more energy than AB attractive forces
Explanation:
AA and BB are separated as solutes and solvents in themselves which is an endothermic reaction ΔH<0 while they are free to react to form the product AB that contains lesser amount of energy than the reactants AA and BB of which the excess energy is observed as increased temperature of the solution
ΔH<0 : Exothermic Reaction (negative), because the the products less energetic than reactants.
Dispersing the molecular bonds of the solute AA and the solvent BB solutions by themselves are generally endothermic reactions in as their cohesive forces are broken down to allow them mix, while allowing the free reaction of the molecules is an exothermic reaction as they form the solution component AB which is less energetic accompanied by excess energy as that is observed in heat of the reaction
