Using the van der Waals equation, the pressure in a 22.4 L vessel containing 1.00 mol of neon gas at 100 °C is ________ atm. (a
svetoff [14.1K]

Answer:

The answer to your question is        P = 1.357 atm

Explanation:

Data

Volume = 22.4 L

1 mol

temperature = 100°C

a = 0.211 L² atm

b = 0.0171 L/mol

R = 0.082 atmL/mol°K

Convert temperature to °K

Temperature = 100 + 273

                      = 373°K

Formula

               (P + \frac{a}{v^{2}} )(v - b) = RT

Substitution

               (P + \frac{0.211}{22.4})(22.4 - 0.0171) = (0.082)(373)

Simplify

               (P + 0.0094)(22.3829) = 30.586

Solve for P

                           P + 0.0094 = \frac{30.586}{22.3829}

                           P + 0.0094 = 1.366

                                 P = 1.336 - 0.0094

                                P = 1.357 atm

Select all the true statements regarding chemical equilibrium.
gladu [14]
Chemical equilibrium is reach when the concentrations of the product and reactants will no longer change with time. this does not mean that there is no change in concentration, only the net change is zero. the forward rate of reaction is now equal to backward rate of reaction.

Please answer these 2 questions it would help me a lot and I’ll give BRAINLIEST Please Help me and answer soon
ipn [44]

Answer:

B) more genetic variation

B) when the organisms produce offspring

Explanation:

More genetic variation means the species is most likely to not die out whenever the environment changes. Take a group of giraffes with varying neck lengths, for example. If the height of the trees were to change, then less of them would die of starvation.

Genes are created through reproduction. During reproduction, an organism with different genes from its parents occurs, creating more genetic variation. Additionally, mutations can also occur, resulting in genes not from either parent.
