A. Chlorine is the most electronegative element out of the possible choices. Generally (though not 100% of the time) electronegativity increases as you go further left and up the periodic table.

Consider the reaction below 2SO2(g) + O2(g) ⇌ 2SO3(g) At 1000 K the equilibrium pressures of the three gases in one mixture were
Vsevolod [243]

Answer:K_p for the reaction is 3.45

Explanation:

The balanced chemical reaction is:

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

At eqm.   0.562 atm   0.101 atm    0.332 atm

As we are given that:

The expression of K_p for above equation follows:

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

Putting values in above equation, we get:

K_p=\frac{(0.332)^2}{(0.562)^2\times 0.101}=3.45

The value of K_p for the reaction is 3.45

A geochemist in the field takes a small sample of the crystals of mineral compound X from a rock pool lined with more crystals o
dedylja [7]

Answer:

1. <u>No, you cannot calculate the solubility of X in water at 26ºC.</u>

Explanation:

You cannot calculate the solubility of X in <em>water at 26 degrees Celsius </em>because you do not know whether the solution formed by dissolving the crystals in 3.00 liters of water is saturaed or not.

The only way to determine the solubility of the compound X is by dissolving the crystals in certain (measured) amount of water and making sure that some crystals remain undissolved, as a solid on the bottom of the beaker.

Next, you should filter the solution to remove the undissolved crystals. Then, weigh the solution, evaporate, wash, dry, and weigh the crystals.

Then you have the mass of the crystals dissolved and the mass of the solution which will let you calculate the mass of pure water, and then the solubility.
