What are the steps to determine isotope fractionation between water and vapor at 25 degrees C?
An equilibrium mixture contains {\rm{N}}_2 {\rm{O}}_4, (P = 0.27 atm) and {\rm{NO}}_2 (P = 1.2 atm) at 350 {\rm K}. The volume of the container is doubled at constant temperature.
What concentrations of [K2HPO4] and [KH2PO4] will you need to make the total concentration 0.50 M? 3.) How many moles of K2HPO4 and KH2PO4 will you need? 4.) What mass of K2HPO4 and KH2PO4 will you need?
If 24 mL of 6.2 M H2SO4 was spilled, what is the minimum mass of NaHCO3 that must be added to the spill to neutralize the acid?
if the density of carbon dioxide in air is .65mg/L, what volume is occupied by 25kg of carbon dioxide?
2. 0.33g of KOH is dissolved in 350.0ml of ethanol and 1.45g of C2H5I is dissolved in 350.0ml of ethanol. Assuming the reaction is first order, when equal volumes of the two solutions are mixed, what is the initial rate at 40oC?
What us the partial pressure (in atm) of carbon dioxide and the partial pressure (in atm) of water vapor? (For the purpose of this question, assume ideal gas behavior.)
liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water. suppose 74 grams of octane is mixed with 148 grams of oxygen
Need help figuring out the proper steps on how to solve -What volume of 1.25M HCl in liters is needed to react completely
Determine the concentration of calcium and chloride in the solution in both mg/L and mmol/L. You will need to find the molecular weights on a periodic table.
rate constant for the decomposition of N2O5 to NO2 and O2 at 70 degree celsius is 6.82 x 10^-3 s-1. Suppose we start with 0.300 mol of N2O5(g) in a .500L container. What is the half-life of N2O5 at 70 degrees celsius?
Classify each of the following solutions as acidic, basic, or neutral. Explain how you reached this conclusion.
if a reation vessel contains .25 mol KO2 AND .15 mol H2O, what is the limiting reactant ? How many moles of oxygen can be formed ?
