how to determine the amount of copper in a soil quantitatively
What volume of dilute nitric acid of density 1.11g/mL and 19% nitric acid by weight contains in 10g nitric acid.
1. How much NH4Cl is required to prepare 100mL of a solution containing 70mg NH4Cl per mL?
CH4 + 2O2 ----> CO2 + 2H2O Heat released is 890.4kJ
How much heat is released by burning 15g of CH4?
Phosgene is a poisonous gas that was used during World War I. It can be formed by the reaction of carbon monoxide with chlorine gas in the equilibrium reaction:
CO(g) + Cl(g) ----> COCl2(g)
The reaction was allowed to proceed at 74*C until equilibrium was reached. The equilibrium concentrations of each species was determined and recorded as follows: [CO]=2.4 x 10^-2 M, [Cl2]=0.108M and [COCl2]=0.28 M. Calculate the equilibrium constant for the reaction at this temperature.
If 0.200 grams CCl4 is mixed with 0.175 grams of SbF3, how many grams of CCl2F2 is formed
