How many moles of lithium nitrate are theoretically produced if we start with 3.4 moles of Ca(NO3)2 and 2.4 moles of Li3PO4?Reaction: 3Ca(NO3)2 + 2Li3PO4 ? 6LiNO3 + Ca3(PO4)2
What is the most important effect of antisymmetrization in electon-electron interaction? Where did antisymmetrization come from? Explain from different statistics of distinguishable particle, indistinguishable particle
draw the organic and inorganic products and select the correct (R) or (S) designation around the stereocenter carbon in the organic substrate and organic product. Include wedge/dash bonds and H on a stereocenter.
The reaction: 2 HI → H2 + I2, is second order and the rate constant at 800 K is 9.70 × 10-2 M-1 s-1. How long will it take for 8.00 × 10-2 mol/L of HI to decrease to one-fourth of its initial concentration.
What gas was evolved when you treated the acetone-bisulfite addition compound with hydrochloric acid?
A buffer solution is composed of 1.360 g of potassium dihydrogen phosphate, KH2PO4, and 5.677 g of sodium hydrogen phosphate, Na2HPO4? What is the pH of the buffer solution
What is the pH at the equivalence point? the Ka of hydrofluoric acid is 3.5x10^-4.
A gaseous sample of this element is bombarded by photons of various energies (in these same units). Match each photon to the result of its absorption (or lack thereof) by an n=1 electron.
Is the system consisting of the aluminum and the water a closed system? Explain your reasoning. If not, how much energy was lost or gained by the system during the experiment
A) How many ions will this compound create in aqueous solution ? B) What is the coordination number of chromium ?
Some observations through an experiment shows that a gas sample of 115 mili litres has a mass of 0.170 grams at a pressure of 711mmHg and a temperature of 34 degree celsius. Determine the molar mass of the gas.
If the O2 gas present in 7.30 L at STP is changed to a temperature of 17 degrees Celsius and a pressure of 788 Torr, what will be the new volume?
Once the pKw's at the three temperatures are determined, the Van't Hoff equation can be used to determine Delta H for the reaction, and from that Delta G, and Delta S can be calculated.
