Examples with good details of saturated compounds
How to do I calculate the pH of original buffer given mass of NaC2H3O2*H2O (FW =136 g/mol) = 3.507 g
An acid with a Ka of 1 x 10-8 is titrated with NaOH, both solutions being 0.020 M. What should the Ka of the indicator be, in order to obtain the best end point
Molten carbonate fuel cells fueled with H2 convert as much as 60% of the free energy released by the formation of water from H2 and O2 into electrical energy. Determine the quantity of electrical energy obtained from converting 1 mole of H2 into H..
The hydrogen is slightly acidic, and it is often used as a primary standard for acid-base tritations because it is solid and air-stable, making it easy to weigh accurately. Its molecular formula is KHC8H4O4. Calculate how many mL of NaOH solution ..
If the colder block orginially weighed 200g and the warmer one 100g. calculate the final temperature and the entropy change of the universe for this process
Car manufacturers are developing engines that use H2 as fuel. In locations where hydroelectric plants produce inexpensive electric power, the H2 can be made industrially by the electrolysis of water.
Write a balanced net ionic equation for the reaction of each of the following aqueous solutions with H+ ions.
Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written
Question- Concentrations of 2 major ions in seawater. Using density of 1.022 g/mL for seawater convert the concentrations for the ions into molality for each ion.
oxalic acid h2c2o4 is a useful primary standard for standardizing solutions such as potassium permanganate kmno4. in a
consider a van parked in a lot outside a professional football stadium in atlanta ga on a sunday afternoon. one ounce
Calculate the mass, in grams, of Ag2CrO4 that will precipitate when 50ml of 0.20M AgNO3 solution is mixed with 40ml of 0.10M K2CrO4 solution. Assume that Ag2CrO4 is completely insoluble (its Ksp is ~ 0).
