A mixture of .100 mol NO, .050 mol H2, .100 mol H2O is placed in a 1.00 liter vessel and allowed to reach equilibirum. [NO]=0.062 M. Reaction: 2NO(g)+2H2(g)=>N2(g)+2H2O(g) Calculate the equilibirum concentration of all the gases( in class my instructor said that a method called the ICE table is useful. do you know how to do that?). b) calculate the numerical value of Kc.
Calculate the change in temperature for 4.5g of CaCl2 dissolved in 90.0mL of H20. Assume that calorimeter absorbs no heat. (Ccal=0)
a 27.7 sample of CO2(g) was collected over water at 25 degree celcius ans 1atm.What pressure due to CO2(g) (the vapour pressure of water at 25c is 23.8 torr? what will the volume be of CO2 be at the same temp and pressure after removing the water ..
What concentration of acetate ion should be present in 0.100 M acetic acid to produce a buffer solution with pH 4.00?
Acetylene gas (C2H2) used in welding, produces an extremely hot ?ame when it burns in pure oxygen according to the reaction 2 C2H2(g)+5 O2(g) -→ 4 CO2(g)+2 H2O(g)
At a certain temperature and pressure 1.4 L of N2 reacts with 2.1 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced?
the permangenate ion and determine the standard reduction potential for the reaction.
