Which cellular molecules would you expect to be soluble in a container of benzene?

1 answer:

3 0

The cellular molecules that you would expect to be soluble in a container of benzene would be the triglycerols which ae fats and oils in the cells, the cholesterol and the chains of fatty acids that are present. Benzene is a nonpolar solvent as it does not have any unequal sharing of electrons in its structure. You would expect that molecules that would have equal charges in their structures or the nonpolar molecules would readily dissolve in this solvent since like dissolves like. Along with this, all polar molecules would not be dissolved and be visible in the mixture since these are not miscible in benzene.

At 920 K, Kp = 0.40 for the following reaction. 2 SO2(g) + O2(g) equilibrium reaction arrow 2 SO3(g) Calculate the equilibrium p

Alex777 [14]

Answer: The equilibrium partial pressure of sulfur dioxide, oxygen and sulfur trioxide is 0.366 atm, 0.443 atm and 0.154 atm respectively.

Explanation:

We are given:

Initial partial pressure of sulfur dioxide = 0.52 atm

Initial partial pressure of oxygen = 0.52 atm

Initial partial pressure of sulfur trioxide = 0 atm

For the given chemical reaction:

$2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)$

Initial: 0.52 0.52

At eqllm: 0.52-2x 0.52-x 2x

The expression of $K_p$ for above equation follows:

$K_p=\frac{(p_{SO_3})^2}{(p_{SO_2})^2\times p_{O_2}}$

We are given:

$K_p=0.40\\\\p_{SO_3}=2x\\\\p_{SO_2}=0.52-2x\\\\p_{O_2}=0.52-x$

Putting values in above equation, we get:

$0.40=\frac{(2x)^2}{(0.52-2x)^2\times (0.52-x)}\\\\x=-1.13,-0.402,0.077$

Neglecting the negative values because partial pressure cannot be negative.

So, x = 0.077

Equilibrium partial pressure of sulfur dioxide = $(0.52-2x)=(0.52-(2\times 0.077))=0.366atm$

Equilibrium partial pressure of oxygen = $(0.52-x)=(0.52-0.077)=0.443atm$

Equilibrium partial pressure of sulfur trioxide = $2x=(2\times 0.077)=0.154atm$

Hence, the equilibrium partial pressure of sulfur dioxide, oxygen and sulfur trioxide is 0.366 atm, 0.443 atm and 0.154 atm respectively.

A student needs to use the metric system while measuring the length of a box. Which units should he use?

Roman55 [17]

Answer:

Centimeters or milimeters.

Explanation:

The answer depends on the size of the box.

The metric system base unit for length is the meter. Centimeters and milimeters are thus also part of the metric system.

If the box is a "regular-sized" box that we use to put stuff in (books, presents, etc), then centimeters would be the most appropiate.

If we're talking about those tiny boxes that are printed on paper (for example in some notebooks) then milimeters would be the most appropiate.

Use the portion of the periodic table shown below to answer the questions. A portion of the first three columns of the periodic

Alja [10]

Part 1: Potassium, and Rubidium.Part 2: Calcium has 20 protons and 20 electrons because the atomic number for calcium is 20 and that determines how many protons there are and in an atom, the number of protons is the same number of electrons. Calcium has about 20 neutrons. I got the number of Neutrons by subtracting the mass number(40.078) and the atomic number(20), I got 20.078. Round to the nearest whole number because you cannot have half or partial neutron. So, Calcium has 20 protons, 20 electrons, and 20 neutrons,
Hope this helps and please mark as brainliest!
