Write a molecular equation for the reaction sodium bromide and sulfuric acid (states of reactants and products must be shown)
Determine the amount of heat produced when 100 g of CH4 combust, CH4 + 2O2 yields CO2 + 2H2O + 1063kJ
Add 1mg of alcohol dehydrogenase. Assuming all of the ethanol is converted to acetaldehyde, what will the final concentration of NADH be in the solution
Assuming the reduced mass associated with the stretch equals the mass of the hydrogen atom, preduct the frequency of the C-D stretch of CDCl3
Which of the following options give the correct relationships between the decimal prefixes? Select all that apply. Pay close attention to the sign and magnitude of exponent. -1 mL= 1x10^3 microliters -1GHz=1x10^6 Hz -10^3 kg=1 g -10^9 nm=1m -10ps=..
Write out all equations (but you do not have to do the integration!) how you would calculate the absolute entropy of Cl2(g) at 298K. For full credit, you must include the limits of integration.
You are given an unknown, colorless, solution that may contain only one salt from the following set: NaA, NaB, NaC. In solution each salt dissociates completely into the Na+ ion and the anion A-, B-, or C-. The Na+ ion is a spectator ion. Given th..
A 0.456 gram sample of an unknown monoprotic acid (let's call it HZ) was dissolved in some water (you pick the amount). Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
