A mixture of hydrazine (N2H4) and hydrogen peroxide (H2O2) is used as a fuel for rocket engines. These two substances react as shown by the equation:
N2H4 + 2H2O2 → N2 + 4H2O
What mass of N2H4, in grams, is needed to react completely with 24.3 g of H2O2?
grams of N2H4

A certain substance, intially present at 0.950 M, decomposes by first-order kinetics with a rate constant of 1.25 x10-2 mol m-1 s-1. calculate the time (in seconds) required for the system to reach a concentration of 0.431M
A saturated solution of lead(II) chloride, PbCl2 , was prepared by dissolving solid in water. The concentration of Pb2+ ion in the solution was found to be 1.62x10^-2 M. Calculate for Ksp for PbCl2.
If yeast were supplied with glucose labelled with 14C at the C-1 position to produce ethanol and CO2 anaerobically, would the label appear in the CO2
Problem- When a metal at a higher temperature is transferred to water at a lower temperature, heat is inevitably lostt to the calorimeter. Will this unmeasured heat loss increase or decrease the calculated value of the specific heat of the metal. ..
