Draw structures of the active sites of the deoxy and oxy form of hemerythrin, showing the complete ligands attached to the central metal ions (drawing N as a ligand is not complete), and give the d-electron count for each metal ion at each site in the deoxy and oxy form.
What is the sum of the simplest whole number ratio coefficients in the balanced chemical equation for complete combustion of C3H8.
Consider the following reaction: CO(g)+2H2(g)-->CH3OH(g) Kp=2.26*10^4 at 25 degrees C. Calculate deltaGrxn under each of the following conditions- At STP, at Equilibrium, and when PCH3OH=1.1 atm, and pCO=pH2=1.3*10^-2 atm.
When the container is re-sealed, the pressure is 185 kPa and the temperature is 10 degrees C. What is the ratio of the amount of gas lost?
Research the number of electrons that can fit into energy levels higher than the third level. Why does that explain why there is a space in the lower periods of the periodic table?
Explain why it is important that the glassware and reagents used in a Grignard reaction are completely dry. Write an equation that describes what happens if phenylmagnesium bromide reacts with water.
list the names and chemical formulas for two allotropes of oxygen, three allotropes of phosphorus, and four allotropes of carbon
A solution containing the thiourea complex of bismuth (III) has a molar absorptivity of 9.32*10^3 l/mol*cm at a wavelength of 470 nm
A white powdery solid, and asked to evaluate its purity and to determine whether it might be identical to a given sample of an illegal drug, a white crystalline solid. Clearly explain what you would do, and how you would interpret your results.
if 50.00ml of Ba(OH)2 solution is mixed with 30ml of HBr solution, what is the pH of the resulting solution. (0.1385 M Ba(OH)2 and 0.2050 M HBr).
The reaction between sodium metal and chlorine gas is highly exothermic and produce NaCl. Comment on this observation relative to the calculated enthalpy for the aforementioned gas-phase reaction.
Consider the following reaction in a closed reaction flask. If 1.50 atm of gas A is allowed to react with 0.500 atm of gas B and the reaction goes to completion at constant temperature and volume, what is the total pressure in the reaction flask a..
In a reaction, 82.00 g of sodium reacts with 74.00 g of ferric oxide to form sodium oxide and iron metal. Calculate the mass of solid iron produced
