A solution of NAOCH3 in methanol can be prepared by adding NaH to methanol (CH3OH). A flammable gas is produced as a byproduct.
a) write the acid-base reaction that takes place
b) write the reaction that takes place when CH3I is added to NaOCH3
One way to make a set of solutions of regularly decreasing concentrations is to make serial dilutions of the most concentrated one. a. starting with
A 1 L solution of 1.5 M acetic acid and 1.5 M sodium acetate has a ph of 4.74. 10 ml of 0.1 M NaOH were added to the solution followed by the addition of 50 ml of 0.02 M HCl.
calculate the enthalpy change for the complete combustion of but-1-ene, according to the following equation.
if a sample of 4.17 L of ethane gas at 725 C is cooled to 175 C at constant pressure, what is the new volume?
methanol, CH3OH can be produced through the reaction of CO and H2. if 75.o grams of CO is used and the typical yield is 79.8%, what mass of methanol is likely to be produced.
predict how many grams of calcium chloride would be produced.
Write the expression for the equilibrium constant, Kb, for methylamine also compute the molar concentration of OH- in the 50.0 mL sample of the CH 3 NH 2 solution.
A catalyst has a avoid fraction of 0.40, an internal surface area of 180 m2/g and a pellet density of 1.40 g/cm3. Estimate the effective diffusivity of thiophene with hydrogen
How much heat does your body lose when 1.5 g of sweat evaporates from your skin at 25 C? (Assume that the sweat is only water.) The heat of vaporization of water at 25 C is 44.0 kJ/mole.
