What is the approximate value of the length of the carbon-carbon bond in ethene?
MAVERICK [17]

Answer:

The answer to your question is: 1.21 A°

Explanation:

Ethene has 1 double bond between its carbons and a single bonds between Carbon and Hydrogens

Structure of ethene

                                H₂C = CH₂

The length of single bonds is 1.42 A°                                    

The length of double bonds is 1.21 A°

The length of triple bonds is 1.10 A°

3. A 0.300 g of gas Y at 3.00 atm was filled in a flask with a volume of 82.0 ml. Calculate
kotykmax [81]

The new volume of gas Y is 89.38 mL

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

Initial volume (V₁) = 82.0 mL

Initial temperature (T₁) = 27.0 °C = 27 + 273 = 300 K

Final temperature (T₂) = 54.0 °C = 54 + 273 = 327 K

Pressure = 3 atm = constant

<h3>Final volume (V₂) =? </h3>

Since the pressure is constant, we shall determine the final volume of gas Y using the Charles' law equation as follow:

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}} \\\\\frac{82}{300} = \frac{V_{2}}{327}

Cross multiply

300 × V₂ = 82 × 327

300 × V₂ = 26814

Divide both side by 300

V_{2} = \frac{26814}{300}\\

<h3>V₂ = 89.38 mL</h3>

Therefore, the new volume of gas Y is 89.38 mL
