Answer
The volume of the container that the gas is in = 874.30 L
Explanation
Given:
Moles, n = 3.2 mol
Pressure, P = 0.095 atm
Temperature, T = 43 °C = (43 + 273.15 K) = 316.15 K
Molar gas constant, R = 0.0821 atm•L/mol•K
What to find:
The volume of the container that the gas occupied.
Step-by-step solution:
The volume of the container that the gas occupied can be calculated using the ideal gas equation.
Therefore, the volume of the container that the gas occupied is 874.30 L
Answer:
B). The equivalence point is where the amount of acid equals the amount of base during any add-base titration.
Explanation:
Equivalence point -
During the process of titration of the neutralization reaction , like acid - base reaction .
In the titration process , the equivalence point is the point , when the amount of acid is equal to the amount of base .
In indicator used for th process is pH sensitive ,
It is not always necessary to have pH = 7 at the equivalence point ,
The titration curve is plotted for the pH v/s base .
Hence , from the given options , the correct statement is ( B ) .
Answer:
If infrared radiation of a given frequency strikes a sample composed of molecules having a vibrational frequency the same as that of the incident radiation, the molecules absorb radiation and the energy of the molecule is increased. However, if the incident frequency differs from the characteristic frequencies of the molecule, the radiation passes through undiminished, or in some experiments, it is reflected. The vibrational frequencies for a particular molecule are determined primarily by the masses of the atoms in the molecule and the strengths of the bonds connecting them. For a diatomic molecule, this frequency can be derived from Hooke's law and is written as:
F=1/2pi*(w/k)^1/2
The energy produced by the reaction
