Volume finding

C16-0112. Suppose that the equilibrium system described in Problem is expanded to twice its initial volume. Find the new equilibrium pressure. 

Reactants are available in separate streams at Ca0 = Cb0 =0.1 mol/liter and both cost 0.50/mol. Fixed costs are 0.01/(hr)(liter of reactor volume). Find the optimum conditions for making 100 mol/hr of product R. 

Exercise. The space outside a sphere of radius R is filled with a medium in which there are p independently diffusing particles per unit volume. Find for the rate at which these particles are absorbed into the sphere ... 

Click on the radio button for volume. Find out what happens to the volume as you change the pressure number of atoms and temperature. As you do this be sure to note which quantities are constant and which are changing. For example with the volume radio button checked, you can find out what happens to the volume when you change the pressure while keeping the number of atoms and the temperature constant. To investigate this in the real world, you would have to set up your apparatus to ensure that these latter quantities remained constant. That can he difficult (how would you ensure that the temperature of the gas didnT change ), which is why a simulation like this one is a valuable tool. 

Boyle s research assistant was Robert Hooke (1635-1703), who would become a famous scientist in his own right. Together they performed a series of experiments that would transform not just the study of matter but the practice of science. Boyle was particularly interested in air, and his great tool for the study of air was the air pump. He looked at the relationship of pressure to volume, finding, for example, that water would boil at a lower temperature at low pressure. His experiments were compiled and published in New Experiments Physico-Mechanicall Touching on the Spring of Air and Its Effects (1660). It was... 

Solutions are often prepared by dilution of more concentrated solutions. If you know that the molarity of one solution times its volume must be equal to the other solution molarity times its volume, find how many milliliters of l.OOMNaCl is needed to make 1.00 L of O.lOOMNaCl solution. 

As series editors, we would like to thank the contributors to this volume - and in particular Fulvio Gualtieri - for their co-operation in its preparation. We feel sure that those scientists who have an interest in new synthetic approaches in medicinal chemistry will, in this volume, find not only an abundance of information on the topics described, but also the guidance and encouragement to apply the appropriate techniques with success. 

Obtain pieces of steel, wood, and concrete of known volume. Find pieces with simple shapes so that you can measure the dimensions and calculate the volume quickly. Determine their mass by pladng eadi on an accurate scale, and calculate their densities. 

Write two consecutive reactions that take place when 40.0 mL of 0.100 M piperazine are titrated with 0.100 M HCl and find the equivalence volumes. Find the pH at = 0,20.0,... 

In each experiment, 0.50 mL of blood was treated with Cr(VI) standard and oxidant. After digestion, the solution was brought to a final volume of 20.0 mL prior to stripping analysis. Prepare a standard addition graph for the case of constant final volume. Find the concentration (and uncertainty) of Cr in the 20.0 mL volume and in the original 0.50 mL of blood. 

Once you calculate the volume, find the radius from the volume using the formula for the volume of a sphere. 

Starting from the relationship between temperature and kinetic energy for an ideal gas, find the value of the molar heat capacity of an ideal gas when its temperature is changed at constant volume. Find its molar heat capacity when its temperature is changed at constant pressure. 

An amount of an ideal gas expands from 12.0 L to 24.0 L at a constant pressure of 1.0 atm. Then the gas is cooled at a constant volume of 24.0 L back to its original temperature. Then it contracts back to its original volume. Find the total heat flow for the entire process. 

A system at equilibrium contains 12(g) at a pressure of 0.21 atm and 1(g) at a pressure of 0.23 atm. The system is then compressed to half its volume. Find the pressure of each gas when the system returns to equilibrium.
