How and why are the lines from the metal salt solutions different from the hydrogen lines. Explain in terms of theory of hydrogen atoms and salt solution atoms.
What mass of CO2 and H20 would be produced during the combustion analysis of 0.1674 g of the cobalamin?
Under standard-state conditions, what spontaneous reaction will occur in aqeuous solution among the ions
The cup is a volume widely used by cooks in the U.S. One cup is equivalent to 237 cm^3. If 1 cup of olive oil has mass of 216 g, what is the density of olive oil in g/cm^3?
An excess of zinc metal reacts with 500. mL of 12M hydrochloric acid and produces 48.8 L of hydrogen gas at 20 degrees C and 750 torr. a)Determine the mass of zinc metal reacted b)Determine the percent yield for the reaction
Phosphorus pentachloride decomposes to phosphorus trichloride at high temperatures according to the reaction: PCl5(g) ?PCl3(g) + Cl2(g)
The density of an unknown gas is 2.00 grams per liter at 3.00 atmospheres pressure and 127 degrees C. What is the molcular weight of the gas?
Enzyme X is a highly pigmented protein that imparts the characteristic color to certain blue-green algae. It also facilitates a reaction necessary to the survival of this species
Hydrogen Sulfide gas has toxicity comparable to Hydrogen Cyanide, but because of its intense odor its presence is observed at concentrations well below toxic levels.
Consider the titration of a 25.0 mL sample of .125M RbOH with .105M HCl. Find the initial pH.
The reaction will be spontaneous at high temperatures because increasing the temperature of a system with a negative change in S eventually results in a positive change in G.
