1. The following reaction has achieved equilibrium. Predict the effect on the formation of phosphorous pentachloride (increase, decrease or no effect) for the stated changes to the system: PCl3(g) + Cl2(g) ? PCl5(g) a) The concentration of phosphorous trichloride is increased. b) The concentration of chlorine is decreased. c) The volume of the container in which the reaction is taking place is suddenly made smaller. d) The pressure of the system is increased by adding one atmosphere of gaseous nitrogen to the container.
2. Newton's third law of motion can be stated like this: "For every action, there is an equal and opposite reaction." How are Le Chatelier's Principle and Newton's third law similar? How are they different?
Determine how much Nitrogen gas is consumed if 13.6 grams of FeN are formed in above reaction?
Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
Write down the full Hamiltonian for a He atom moving freely in space, i.e., there is no external potential. b) Now assume there is no repulsion between the electrons
Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all atoms in the correct structure.
How Much Chlorine Must be Added to a Swimming Pool? A solution used to chlorinate a home swimming pool contains 7% chlorine by mass. An ideal chlorine level for the pool is one part per million (think of 1 ppm as being 1 g chlorine per million gra..
Draw the Major Organic Products that will form when (E)-3-methyl-3-hexene reacts with ozone
In chemical reactions the total number of moles of products must be the same as the total number of moles of reactants.
Explain the bond and angle terms of this structure, not confident about what it is - it looks like a ring structure and I have been unable to find it using familiar web searches.
Use the Frost Circle to draw the energy levels of the Pi molecular orbitals for this ion, show the electronic configuration and explain why the ion is aromatic.
If 69.5 kJ of heat is applied to a 1040. g block of metal, the temperature of the metal increases by 11.4°C. Calculate the specific heat capacity of the metal in J/g°C.
