Bromobutane can be converted to butanol using aqueous potassuim hydroxide solution. Outline one possible method. that does NOT involve the use of rate experiments, of determining wether the mechanism of the reaction is SN1 or SN2
The solubility of oxygen in lakes high in the Rocky Mountains is affected by the altitude. If the solubility of O2 from the air is 2.67 × 10-4 M at sea level and 25°C.
Write one overall equation, using an alkali metal ion and a nitrate ion as spectator ions if needed, for the following net ionic equation: H+(aq) + OH-(aq) ? H2O(l)
What is the volume percent concentration of (a) 35.0mL of water in 725mL of an ethanol-water solution,and (b) 78.9mL of acetone in 1550
a 5.0 g sample of a hydrate of CaCl2 was heated, and only 4.3 g of the anhydrous salt remained. what percentang of water was in the hydrate?
volume of 2.25 L at 278 K and 1.01 atm. Calculate the pressure when the volume is 1.95 L and the temperature is 303 K.
Determine value for the rate of formation of HCl during the same interval of 3 seconds If the rate of disappearance H2 = -0.13 M/s at this specific time?
A chemist is commissioned to produce 50,000 liters of 0.550 M aqueous phosphoric acid. The chemist can purchase solid, 98.64% pure, phosphoric acid to dissolve in water. How many grams of this reagent are required?
A sample of Br2(g) takes 34.0 min to effuse through a membrane. How long would it take the same number of moles of Ar(g) to effuse through the same membrane
How much heat in kilojoules is required to warm 10.0g of ice, initially at -20.0^\circ C, to steam at 110^\circ C. The heat capacity of ice is 2.09 {\rm J}/{\rm g} ^\circ {\rm C} and that of steam is 1.84 {\rm J}/{\rm g} ^\circ {\rm C}.
If 100. grams of liquid water at 100.0 C and 200. grams of water at 20.0 C are mixed in an insulated container, what will be the final temperature of the water? The specific heat of water is 4.18 J/g
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more com- plicated, but this is a reasonable ?rst ap proximation.)
dissolving 3.00 g of an impure sample of CaCo3 in an excess of HCl produced 0.656 L of CO2 (measured at 20 C and 792 torr) . Calculate the percent by mass of CaCO3 in the sample
