While performing sn2 chemistry- synthesis of 1-bromobutane from butan-1-ol, Explain what would be the purpose of refluxing the RXN mixture for 30 minutes as an alternative of just boiling and what would need modified if you used 1-chlorobutane instead?
Consider the following experimental data set obtained for the density of a metal object as measured by three students in the laboratory: 6.02g/mL, 6.04g/mL, and 6.05g/mL. The actual density of the object is known to be 5.00g/mL. Calculate the abso..
ammonia undergoes autoionization by the transfer of a proton: 2NH3 NH4+ + NH2-, K = 1×10^-33 at -50°C Since ammonia is better proton acceptor than water, the ionization of acids is relatively enhanced in liquid ammonia. For example, acetic acid i..
What total mass of hydrogen is contained in 7.1 g of solution that is 51 % hydrogen peroxide
at 1000 k the total equilibrium vapor pressure over liquid bismuth metal is 4.84 x 10-5 atm. it is known from mass
a basketball is inflated to 9.0 psi (pounds per inch) above atmosphere pressure of 14.7 psi ( a total pressure of 23.7 psi). The diameter of the basketball is 10 inches. What is the pressure of the air in the basketball, expressed in atmospheres?
Trichloroethane has a vapor pressure of 100.0 mm Hg at 20.0 C and boils at 74.1 C. An uncovered cup (1/2 pint) of trichloroethane (d=1.325 g/mL) is kept in an 18-ft3 refrigerator at 39 F. What percentage (by mass) of trichloroethane is left as a l..
Carbon-12 contains 6 protons and 6 neutrons. The radius of the nucleus is approximately 2.7 (femtometers) and the radius of the atom is approximately 70 (picometers). Calculate the volume of the nucleus and the volume of the atom.
Sodium peroxide (Na2O2) reacts with water to form sodium hydroxide and oxygen gas. Write a balanced equation for this reaction and determine how much oxygen (in grams) is formed by the complete reaction of 35.23g of Na2O2.
During a standarization of sodium hydroxide solution, it takes 12.35mL of 0.100 M HCl(aq) to neutralize a 25.00 mL sample of the NaOH(aq) solution. What is the concentration of the NaOH(aq) solution?
