Where could you find hydrocarbon chains?
ser-zykov [4K]

Answer: Most Hydrocarbon chains are found in petroleum, coal, and natural gas. First of all, a hydrocarbon chain is a molecule that consist of entirely hydrogen and carbon.

Explanation: There are many types of hydrocarbon chains, which can be found in alkanes, alkynes, arenes, alkenes, and cycloalkanes. Natural rubber for instance is a hydrocarbon that primarily consists of alternating single and double bonded carbons.

In an experiment, 0.42 mol of co and 0.42 mol of h2 were placed in a 1.00-l reaction vessel. at equilibrium, there were 0.29 mol
Likurg_2 [28]
To determine the Keq, we need the chemical reaction in the system. In this case it would be:

CO + 2H2 = CH3OH

The Keq is the ration of the amount of the product and the reactant. We use the ICE table for this. We do as follows:

          CO           H2             CH3OH
I         .42           .42                    0
C     -0.13      -2(0.13)            0.13
-----------------------------------------------
E =    .29           0.16               0.13

Therefore, 

Keq = [CH3OH] / [CO2] [H2]^2 = 0.13 / 0.29 (0.16^2)
Keq = 17.51

A sample of a gas in a 4L container at 300K has a pressure of 1 atm. If the
zavuch27 [327]

The final pressure of the gas in the container is 4 atm

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

Initial volume (V₁) = 4 L

Initial temperature (T₁) = 300 K

Initial pressure (P₁) = 1 atm

Final temperature (T₂) = 600 K

Final volume (V₂) = 2 L

<h3>Final pressure (P₂) =?</h3>

  • Using the combine gas equation, we can obtain the final pressure of the gas as illustrated below:

\frac{P_{1} V_{1} }{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}\\\\\frac{1 * 4}{300} = \frac{P_{2} * 2}{600} \\\\

Cross multiply

300 × 2 × P₂ = 4 × 600

600 × P₂ = 2400

Divide both side by 600

P_{2} = \frac{2400}{600} \\\\

<h3>P₂ = 4 atm</h3>

Therefore, the final pressure of gas is 4 atm.
