Beer's Law states that A=ebc, where A is the absorbance, ε is the molar absorptivity of the solute, b is the path length, and c

is the concentration. Identify the experimental evidence from the activity that you have for the dependence of absorbance on each variable
The evidence for the dependence of absorbance on the variable ε is:_________

a. increasing the cuvette width increases the absorbance.
b. changing the compound changes the absorbance behavior.
c. adding more water decreases the absorbance.

Answer:

b. changing the compound changes the absorbance behavior.

Explanation:

  • Option a) would be akin to modifying the <em>path length</em>, b.
  • Option b) would involve using a different solute, as such, there would be another <em>molar absortivity</em>, ε.
  • Option c) would decrease the<em> concentration</em> (c) of the solute, which would explain why the absorbance would decrease as well.

DedPeter [7]

Answer:

moles HCl = 101.2 g /36.461 g/mol=2.78

[H+]= 2.78 mol/ 150 L =0.0185

pH = - log 0.0185=1.73

1.73 is the answer

renewable resources:  a natural resource that is unlimited or that is naturally replenished rather quickly, such as sunlight or water

non renewable resources: (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.

A) A sample of ideal gas is in a sealed container. The pressure of the gas is 725 torr, and the temperature is 18 ∘C. If the tem
Fudgin [204]

Answer:

a. The new pressure is 606,25 Torr.

b. -243,9°C is needed to reach the pressure of 7250 Torr.

Explanation:

Gay Lussac's law for gases says that if the volume in a gas remains constant, the pressure will be directly proportional to the temperature change.

P1 . T1 = P2. T2

(Temperature must be in K)

725 Torr . 291 K = P2 . 348 K

(725 Torr . 291 K) /348 K = P2

606,25 Torr = P2

725 Torr . 291K = 7250 Torr . T2

(725 Torr . 291K) /7250 Torr = T2

29,1 K = T2

T° K - 273 = T°C

29,1 K -273 = -243,9°C
