Phosphorous trichloride and phosphorous pentachloride equilibrate in the presence of molecular chlorine according to the reaction: PCl3(g) + Cl2(g) → PCl5(g). An equilibrium mixture at 450 K contains the following:
PPCl3 = 0.202 atm
PCl2 = 0.256 atm
PPCl5 = 3.45 atm
What is the value of Kp at this temperature?
- Write a paraphrase of each of the following sentences:
- Many invertebrates, such as snails and worms and crustaceans, on the other hand, have a spiral pattern of cleavage.
- Similarly, the muscles will not grow in length unless they are attached to tendons and bones so that as bones lengthen, they are stretched.
- Besides being a theory about the basis and origin of knowledge and the contents of our minds in general, empiricism is also sometimes a methodology.
- As opposed to this, Locke is often supposed to be saying that, in addition to properties, things have a “substratum” which “supports” their properties.
Create a method called emptySpace () this remove space between the name and the surname (Use a regular expression "replaceAll"). The emptySpace() method also Count the number of characters within the newly created string (nameSurname) and return the total number of Characters .
The total number of characters (Name and Surname) should be the size of your arrayAlphabetizer (type integer). Populate your arrayAlphabetizer with a series of random numbers between 10 and 50.
Display all arrayAlphabetizer elements and they are corresponding indexes before executing the sort() method and after executing the sort().
Allow the user to enter a value from the arrayAlphabetizer element to search for.
* * Loop through the array until you find the value (Use a Search function to locate the value with in the array) and replace that value with the character @.
* *Print out arrayAlphabetizer with the replaced element..
A ball is tossed straight up at 24m/s. Estimate its velocity at 1s interval, and when will it reach its original starting poin
In the coal-gasification process, the reaction is: CO(g) + H2O(g) ⇌ CO2(g) + H2S(g) + H2(g). With 0.35 mol of CO and 0.40 mol of H2O placed in a 1.00-L reaction vessel, there is 0.19 mol of CO remaining. Determine the Keq at the temperature of the experiment?
Dinitrogentetraoxide partially decomposes according to the following equilibrium: N2O4(g) ⇌ 2NO2(g). A 1.00-L flask is charged with 0.04000 mol of N2O4. At equilibrium at 373 K, 0.0055 mol of N2O4 remains. Determine the Keq for this reaction.
Two mole of an ideal gas is heated at a constant pressure of 101.3K Nm-2 from 273.2 K to 373K. Calculate, in Joules, the work involved
