Find the volume of hydrogen evolved when 3.25g of zinc granules react completely with excess hydrochloric acid solution (Zn=65)
3H2 + N2 -> 2NH3. At 200 degrees C in a closed container, 1.00atm of nitrogen gas is mixed with 2.00atm of hydrogen gas. At equilibrium, the total partial pressure is 2.00atm.
A sample of nitrogen gas in a 4.4-L container at a temperature of 35°C exerts a pressure of 3.7 atm. Calculate the number of moles of gas in the sample.
A compound contains 10.13% C, and 89.87% Cl (by mass). Determine both the empirical formula and the molecular formula of the compound given that the molar mass is 236g/mol
The standard molar heat of fusion of ice is 6020 J/mol. Calculate q, w, and E for melting 1.00 mol of ice at 0C and 1.00 atm pressure.
Using the values for the resonance energies of benzene and naphthalene given above, explain why Diels-Alder reactions of anthracene take place at the center ring, not one of the end rings.
If you know the answer please give units :) Part A: The reactant concentration in a zero-order reaction was 5.00×10^?2M after 140s and 3.00×10^?2M after 300s. What is the rate constant for this reaction? -> For this I got that 1.25x10^-4M/s, whic..
