Sucrose (C12H22O11) can be mixed with potassium nitrate to form an amateur rocket propellant called rocket candy, which, despite its name, is at least mildly toxic. The properly balanced mixture reacts to form K2CO3, N2, H2O and CO2. Write the balanced reaction and determine the mass of KNO3 that should be mixed with 0.4 g of sugar to produce optimally balanced rocket candy.
do not specify stereochemistry. (The absolute stereochemical configurations of chiral substances cannot be determined from the data.)
If a solution containing 60.998 g of mercury(II) perchlorate is allowed to react completely with a solution containing 10.872 g of sodium sulfide, how many grams of solid precipitate will be formed?
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.
a researcher plans to compare two treatment conditions by measuring one sample in treatment 1 and a second sample in
What is the half-life of a compound if 78 percent of a given sample of the compound decomposes in 45 min? Assume first-order kinetics.
Take 7 test tubes from the Glassware shelf and place them on the workbench. Add 1g of the seven metals on the chemicals shelf (Ag, Ca, Cu, Fe, Mg, Pb, Zn) into the seven test tubes, one metal per test tube.
How is quantitation achieved in XPS and how does it depend upon analyte concentration
the mass of a proton is 1.673 sdot 10-24 g. the mass of a neutron is 1.675 sdot 10-24 g. the mass of the nucleus of an
If an acid base reaction produces a solution with a pH of 7 at its equivalence point, why does an indicator solution that changes color at either a pH of 5 of 9 work just as well as one that changes at a pH of 7
