A student was asked to determine the strength of the acetic acid in a vinegar solution. For 25.00 mL of vinegar he used 32.05 mL of a 0.4235M solution of sodium hydroxide to neutralize using phenolphthalein as indicator. What was the concentration..
Starting out on a road trip you inflate your tires on your car to the recommended pressure of 46.5 psi on a day when the temperature is -5.0 C. Upon arrival at your destination, the temperature is now 28.0 C/ The volume of the tires has increased ..
How many photons will be required to raise the temperature of 2.3 g of water by 2.1k ? Water is exposed to infrared radiation of wavelength 2.7×10?4 cm . Assume that all the radiation is absorbed and converted to heat.
Using chemical equations, show how the triprotic acid H3PO4 ionizes in water. Phases such as (l) or (aq) are optional Ka1 = ? Ka2 = ? Ka3 = ?
How many gram of each of the following substances will dissolve in 100 mL of cold water. Ce(IO3)4 RaSO4 Pb(NO3)2 (NH4)2SeO4
What is the pressure inside the system when the stopcocks are opened. Assume that the lines connecting the bulbs have zero volume and that the temperature remains constant.
why was the titration performed by the addition of permanganate solution to oxalate solution and not the other way
When an ionic solid dissolves in water, water molecules attract the ions causing them to dissociate of come apart. The resulting dissolved ions are electrically charged particles that allow the solution to conduct electricity. The following chemic..
A 0.2527-g sample of a mixture of Mg(OH)2 and Al(OH)3 was treated with 50.00 mL of 0.225 mol L 1 HCl(aq). The resulting solution required 13.73 mL of 0.176 mol L 1 NaOH(aq) to neutralize the excess, unreacted HCl.
