I am recalling this equation from memory, so I hope it’s accurate. We last used it about four months ago in my chemistry class:

(P-(n^2•a)/V^2)(V-nb)=nRT

Substituting the provided values:

(P-(1•1.35)/(1.42^2))(1.42-(1•0.0322))=(1)(0.0821)(300)
(P-(1.35/2.016))(1.42-0.0322)=24.63
(P-(1.35/2.016))=17.75
P=18.42 atm

Therefore, the pressure from the Argon gas amounts to 18.42 atmospheres.

32.7 grams of water vapor takes up how many liters at standard temperature and pressure (273 K and 100 kPa)?
alisha [2963]
At standard temperature and pressure, it is established that 1 mole of gas has a volume of 22.4 liters.

According to the periodic table:
the molar mass of oxygen is 16 g
and the molar mass of hydrogen is 1 g
Hence, the molar mass of water vapor is calculated as 2(1) + 16 = 18 g

Thus, 18 g of water occupies 22.4 liters, therefore:
the volume for 32.7 g is (32.7 x 22.4) / 18 = 40.6933 liters

How many 2º alkyl bromides, neglecting stereoisomers, exist with the formula c6h13br?
Anarel [2989]

A secondary alkyl halide would be characterized by having a carbon atom connected to two other carbon atoms, with bromine attached to that carbon.


Therefore, bromo-hexane qualifies as a 2-degree or secondary alkyl halide

PLEASE HELP!! What direction do you predict the addition of a base to the solution containing bromophenol blue will drive the eq
Alekssandra [3086]

Answer:

Here is an explanation related to the same question.

Explanation:

  • According to Le Chatelier's principle , when the balance of a system is disturbed by external changes, the system adapts by altering the concentrations of its components in a manner that counteracts the disturbance, thus achieving a new stable equilibrium of concentration that differs from its previous state.
  • Bromothymol blue is known to function as a phenolic compound that operates effectively as an acid in water solutions. Because it is classified as a weak acid, it should not react rapidly, while simultaneously establishing equilibrium with its largely unrelated form.

For such a weak diprotic acid, the typical economic expression can indeed be articulated as:

    ⇒  H_2In_(aq)\rightleftharpoons In^{2-} +2H^+

  • It can be ultimately shown through Le Chatelier's concept that when a strong acid is introduced, the complete disorientation of either component influences an increase in the proton levels within the medium.
  • Likewise, it takes up protons throughout the medium leading to the breakdown of water each time a solution is introduced. Consequently, the concentration of particles in the medium decreases. To adjust for this change, the equilibrium shifts appropriately, thereby prompting further dissociation of the respective acid into its dianion in the presence of protons, aiming to nullify the initial disturbance.

A metallic object holds a charge of −4.8 × 10−6 C. What total number of electrons does this represent? (e = 1.6 × 10−19 C is the
Anarel [2989]

Answer:

n=3.0\times 10^{13}

Explanation:

Charge of one electron = -1.6\times 10^{-19}\ C

The formula for calculating charge is:

Charge=n\times q_e

Given that: Charge = -4.8\times 10^{-6}\ C

-4.8\times 10^{-6}=n\times (-1.6\times 10^{-19})

n=\frac{4.8\times 10^{-6}}{1.6\times 10^{-19}}=3.0\times 10^{13}

Total electrons, n = 3.0\times 10^{13}
