Answer:

1.4 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V1) = 1.3 L

Initial temperature (T1) = 280 K

Final temperature (T2) = 303 K

Final volume (V2) =?

With the above data, we can obtain the new volume of the gas by using the Charles' law equation as shown below:

V1 /T1 = V2 /T2

1.3/280 = V2 /303

Cross multiply

280 × V2 = 1.3 × 303

280 × V2 = 393.9

Divide both side by 280

V2 = 393.9/280

V2 = 1.4 L

Thus, the new volume of the gas is 1.4 L

Last friday the atmospheric pressure in our 2nd year lab was measured as 731 mmhg. Calculate the temperature at which water woul
faust18 [17]

Answer:

p1/T1=p2/T2

760mmHg/212°F=731mmHg/T2

T2= 203.91°F

760mmHg/100°C=731mmHg/T2

T2= 96.18°C

Explanation:

You'd have to choose in which units you want to express the temperature.

Calculate your % yield of co2 in the reaction based on the grams of nahco3 being the limiting reagent in the reaction.
Lynna [10]

The percent yield of CO₂ is 93.3%.

<h3>What is the percent yield of CO₂?</h3>

The percent yield of a substance is given as follows:

  • Percent yield = actual yield/theoretical yield * 100 %

The equation of the reaction is used to determine the theoretical yield.

  • NaHCO₃ + CH₃COOH → CH₃COONa + H₂O + CO₂

Moe ratio of sodium bicarbonate and CO₂ is 1 : 1.

Given that sodium bicarbonate is the limiting reactant, the theoretical yield of CO₂ will be:

Moles of NaHCO₃ reacting = 2.01/84 = 0.0239 moles

Theoretical yield of CO₂ = 0.0239 moles * 22.4L/mol = 0.536 L

Actual yield = 0.50 L

Percent yield = 0.50/0.536 * 100%

Percent yield = 93.3%

In conclusion, the percent yield is the ratio of the actual yield and theoretical yield.

<em>Note that the complete question is given below:</em>

<em>Calculate your % yield of co2 in the reaction based on the grams of nahco3 being the limiting reagent in the reaction between 2.01 g of sodium bicarbonate and 24.6 mL of 1.5 M acetic acid? They produce 0.50 L of at s.t.p.</em>
