Answer : Option B) Air
Explanation : As the speed of light depends on the refractive index of the medium; then according to Snell's law (refer the attachment) Air is the medium that would have the longest wavelength amongst the given options.
As the refractive indexes of water is 1.33, glass is 1.5 and diamond 2.42 are much higher than air. Therefore, it will be the medium which will allow maximum light to pass through it easily and hence, will be the medium with longest wavelength.
Answer:
V=12.6148888506L
Explanation:
using charles law Volume1/Temperature1 = Volume2/Temperature2
13.4L/(17C+273.15C)=V/273.15K
remember gas equations require kelvin not celcius so converting celcius to kelvin is Celcius + 273.15 which is standard temperature conditions
The concentration of the diluted solution will be 2.44%.
<h3>Dilution problem</h3>
From the equation of dilution:
(M1)(V1) = (M2)(V2).
where M1 = concentration before dilution, M2 = concentration after dilution, V1 = volume before dilution, and V2 = volume after dilution.
In this case:
V1 = 17.06 mL
V2 = 50.00 mL
M1 = 7.16%
M2 = ?
M2 = (M1)(V1)/(V2)
= 7.16 x 17.06/50
= 2.44%
Thus, the concentration of the diluted solution is 2.44%.

Answer:
The pressure of CO2 = 0.48 atm
Explanation:
Step 1: Data given
Kp = 0.23
Step 2: The balanced equation
2NaHCO3(s) ↔ Na2CO3(s) + CO2(g) + H2O(g)
Step 3: Calculate the pressure of CO2
Kp = (p(CO2))*(p(H2O))
For 1 mol CO2 we have 1 mol H2O
x = p(CO2) = p(H2O)
Kp = 0.23 = x*x
x = √0.23
x = 0.48
pCO2 = x atm = 0.48 atm
The pressure of CO2 = 0.48 atm
