The expansion work on an irreversible system is equal to:
W = - PV
Assuming that the gas is ideal, therefore:
PV = nRT
[P=pressure, V=volume, n=number of moles, R=gas constant,
T=absolute temperature]
Therefore,
W = -nRT
W = -(1 mol) * (8.314 J / mol K) * (1250 K)
W = -10,392.50 J
Therefore about 10,392.50 J or 10.4 kJ of work is done on
the system.
Answer:
What will determine the number of moles of hydronium in an aqueous solution of a strong monoprotic acid? The amount of acid that was added.
Explanation:
Acids are chemicals with a pH less than 7 that can donate a proton or H+ ion in a reaction. Bases have a pH greater than 7 and can accept a proton or produce an OH- ion in a reaction. If you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water. Mixing equal amounts of a strong acid with a strong base also produces a neutral pH (pH = 7) solution. This is called a neauturization and looks like
HA + BOH → BA + H2O + heat
Two or more substances that are blended together but not chemically combined make up a mixture.
Answer:
Two constitutional isomers for the compound C3H8S are shown in the attachment below
Explanation:
Constitutional isomers are isomers that have the same molecular formula but different connectivity. Two constitutional isomers for the compound C3H8S are shown in the attachment below.
