A waste containing 10,000 mg/L sulfuric acid is neutralized by the addition of concentrated lime slurry [Ca(OH)2]. If the water temperature is 15 degrees Celsius before neutralization, what is the temperature after neutralization? Note that the heat capacity for water s 4.184 J/g - degrees C. Because you are given a concentration of acid reacted, it will be convenient to find the heat generated on a per volume basis as well (i.e, use the density of water instead of the mass of water).
Write the net ionic equations that occur in the following cells: a. Pb|Pb(NO3)2||AgNO3|Ag Pb + 2Ag+ --> Pb2+ + 2Ag b. Zn|ZnCl2||Pb(NO3)2|Pb Zn + Pb2+ --> Zn2+ + Pb c. Pb|Pb(NO3)2||NiCl2|Ni Pb + Ni2+ --> Pb2+ + Ni
The aqueous solubility of CO2 at 20 degrees Celsius and 1.00 atm is equivalent to 87.8 mL of CO2(g), measured at STP, per 100 mL of water. What is the Molarity of CO2, in water, that is at 20 degrees Celsius and saturated with air at 1.00 atm. The..
