For the answer to the question above, the number of naturally occurring elements is actually in dispute, believe it or not. Some say 98, others say 88 and all cite various reasons. The traditionally accepted answer would be 92.

zhannawk [14.2K]

In this drama, a crucible would represent the constant building action leading to the climax of the pot.

What is crucible?

A crucible is a ceramic as well as metal vessel used to melt metals or subject other substances to extremely high temperatures. Crucibles can be made from any material that can withstand temperatures high enough to melt and otherwise change their contents, despite historically being most frequently made of clay. The crucible's shape has changed over time, with designs that take into account both regional variation and the process for that they are used. The earliest crucible forms date to Iran and Eastern Europe in the sixth or fifth millennia B.C.

Similar to the contents of a crucible, the characters seem to be constantly enduring severe trials; in this case, the witching trials. The crucible would, in my opinion, symbolize the town itself and its residents. The symbolism of this suggests a theme of the townspeople going through the witching trials and coming out with a "refined" lesson. The unnecessary accusations and trials will teach a hard lesson to the people who live within the town and influence their future.

Calculate the solubility of carbon dioxide at 400 kPa.
BaLLatris [955]

The solubility of carbon dioxide at 400 kPa  at room temperature is ;

( B ) 0.61 CO2/L

<u>Given data </u>

pressure of CO₂ = 400 Kpa = 3.95 atm

Kh of CO₂ = 3.3 * 10⁻² mol/L.atm

<h3>Calculate the solubility of carbon dioxide </h3>

Solubility = pressure * Kh value of CO₂

                = 3.95 atm * 3.3 * 10⁻² mol / L.atm

                = 0.13 mol/l  CO₂

                = 0.61 CO₂ / L

Hence we can conclude that the solubility of CO₂ at 400 kPa is 0.13 mol/l  CO₂.
