Iron pyrite (fes2) is the form in which much of the sulfur exists in coal. in the combustion of coal, oxygen reacts with iron pyrite to produce iron(iii) oxide and sulfur dioxide, which is a major source of air pollution and a substantial contributor to acid rain. what mass of fe2o3 is produced from 84 l of oxygen at 3.41 atm and 148◦c with an excess of iron pyrite? answer in units of g.

Explanation:

For this case we have the following equation:

After balance the equation.

For this case we can use the following expression for an ideal gas:

And if we solve for we got:

The mass for the is given by: , since we have 2 molecules of iron and 3 from oxygen.

For this case since the pyrite is the excess reactive we can calculate the amount of with the oxygen and we can do this:

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
