How many ml of 0.50M KOH is needed to react completely with 60.0ml of 0.250M FeCl2 solution to percipitate Fe(OH)?
2. A reaction is carried out between 200ml of 0.12M Pb(NO3)2 and 3.0g Zn. Calculate the mass of Pb(s) produced.
3. A mixture consists of 50.0ml of 0.10M H2SO4 and 50.0ml of 0.30M Ba(OH)2. Calculate the mass of solid produced.
4. How many grams of Epsom Salt (MgSo4•7 H2O) arr needed to react completely with 100.0ml of 0.100M BaXl2 solution?
5. A mixture is prepared by adding 20.0ml of 0.200m Na3PO4 to 30.0ml of 0.150M Ca(NO3)2.
A) what weight of Ca3(PO4)2 will be formed?
B) what will be the concentrations of each of the ions in the mixture after reaction?
Please show the work for these answers :(
I really need help with my chemistry ASAP!!
