if 22.8 ml of 0.100 m mgcl2 is needed to completely react 15.0
ml of agno3 solution, what is the molarity of the agno3 solution?
the reaction is: mgcl2(aq)+2 agno3(aq)->2
afcl(s)+mg(no3)2(aq)
1) Calculate the amount of 1.50 M Na2CO3 needed to react
completely with 25.0 mL of 0.500 M CaCl2.
2) Calculate the theoretical yield of chalk (calcium carbonate)
for each reaction (#1 & #2)—show all calculations. For reaction
#1 CaCl2 should be limiting and for reaction #2 Na2CO3 should be
limiting. You need to figure out how much sodium carbonate solution
you will use in your experiment
Na2CO3(aq) + CaCl2(aq)
àCaCO3(s) + 2NaCl(aq) (molecular
equation)
CO32–

75.0 mL of 0.200 M AgNO3 is combined with 125.0 mL of 0.100 M
Nacl. solid AgCl forms.
a) what mass of AgCl forms ?
b) what is the concentration of each of the 4 ions in the final
solution ? assume that volumes are additive. note.... none of the
concentration will be zero.'
-Ag , Na , NO3 and Cl
A 50.0 mL sample of 0.0645 M AgNO3(aq) is added to 50.0 mL of
0.100 M NaIO3(aq). Calculate the [Ag+] at equilibrium in the
resulting solution. The Ksp value for AgIO3(s) is 3.17 × 10-8.
[Ag+] =____ mol/L
a) A beaker contains 200.0 mL of 0.250 M AgNO3. 200.0 mL of
0.100 M HCl(aq) is added to it. What is the NO3− concentration in
the final mixture?b) What is the Ag+(aq) concentration in the final
mixture? (Hint: does anything happen when you mix these
solutions?)
When 20.0 mL of 0.200M AgNO3 and 30.0 mL of
0.100 M NaCl, both at 24.71°C. are mixed
in a coffee-cup calorimeter, AgCl precipitates and the temperature
of the mixture increases to 25.65°C. Calculate
ΔH in kJ per mole of AgCl(s) produced. (Assume
that the total volume is the sum of the volumes and that the
density and specific heat capacity of the solution are the same as
for water.)
13. A 15.0 mL NaOH solution is required to neutralize
10.0 mL of 0.100 M H2SO4(aq)
solution.
What is the concentration
of NaOH solution used?
2NaOH (aq) + H2SO4(aq) → Na2SO4(aq) +
2H2O(l)
What volume (in mL) of a 0.125 M HNO3 solution is required to
completely react with 39.8 mL of a 0.102 M Na2CO3 solution
according to the following balanced chemical equation?
Na2CO3(aq)+2HNO3(aq)→2NaNO3(aq)+CO2(g)+H2O(l)
