After the completion of a gas forming reaction, the column of water remaining in the collection flask was measured to me 55 mm h

igh, the vapor pressure of water is 0.0313 atm at 25oC, and the atmospheric pressure that day was measured as 0.950 atm, what is the partial pressure of the gas produced by the reaction

Answer:

The partial pressure of the gas produced by the reaction is 0.9187 atm

Explanation:

Given;

vapor pressure of water, \rho_w = 0.0313 atm

measured atmospheric pressure, P_{Total} = 0.950 atm

partial pressure of the gas produced by the reaction = ?

According to Dalton's law of partial pressure; total pressure is equal to sum of partial pressure of water vapor and gas produced.

P_{Total} = P_{gas} + P_{water}

P_{gas} = P_{Total} -P_{water}

P_{gas} = 0.95 - 0.0313

P_{gas} = 0.9187 atm

Therefore, the partial pressure of the gas produced by the reaction is 0.9187 atm

Answer:

T_2=-125.58\°C

Explanation:

Hello!

In this case, considering the Gay-Lussac's law which describes the pressure-temperature behavior as a directly proportional relationship by holding the volume as constant, we write:

\frac{T_1}{P_1} =\frac{T_2}{P_2}

Whereas solving for the final temperature T2, we get:

T_2=\frac{T_1P_2}{P_1}

Thus, we plug in the given data (temperature in Kelvins) to obtain:

T_2=\frac{(22+273.15)K*1.75atm}{3.50atm} \\\\T_2=147.58K-273.15\\\\T_2=-125.58\°C

Best regards!

Is it the power of material evidence that wins, not the authority of experts that
kvasek [131]

Yes, it is the power of material evidence that wins.

  • Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
  • Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
  • Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
  • A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
  • Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.

Therefore, it is the power of material evidence that wins, not the authority of experts that

proves an answer in Science.
