Can some one verbally explain the ideas of tunneling and reflection in the case of particles confronting an energy barier?
what is the product of the reaction of CsCl and SnCl4 and what is the role of cesium chloride in the reaction
When you combine 2-ethoxybenzaldehyde and 4-heptanone what is the product and structure of that product. With 95% ethanol and 3M sodium hydroxide
if you burn 10.00g of octane. if the temperature is 500K, and you have an expansion of 1.00 atm, how much work in joule can be done by the system if the octane is completely converted to CO2 and water vapor. what will be the enthalpy change
given the pk for acetic acid is 4.76. suppose that we dissolve a mole of this weak acid in 10l of water. find the ph of
Write the half reactions and the blanced equation for the galvanic cell: Ag(s) | AgCl(s) | Cl^-(aq) || Cl^-(aq) | Hg_2Cl_2(s) | Hg(l).
Place drying tube filled with CaCl2 on condenser. Heat to reflux at 190 C for 25 minutes then cool. Add 0.5mL tolulene and petroleum ether 0.5-0.75 mL until slight cloudiness remains. Reheat until clear and cool in ice bath. Collect product and wa..
110 micro mol of 206^Pb. Assuming that all the 206^Pb comes from decay of the 238^U, estimate the rocks age (in yr).
Calculate the vapor pressure of a solution made by dissolving 109 grams of glucose
The cup is a volume widely used by cooks in the U.S. One cup is equivalent to 237 cm^3. If 1 cup of olive oil has mass of 216 g, what is the density of olive oil in g/cm^3?
use curved arrows to show the flow of electrons in each step, and note any relevant charges or lone pairs of electrons.
The rate at which a metal alloy oxidizes in an oxygen containing atmoshphere is a type of the Arrhenius equation (rate(k)=Ce^(-Q/RT)). For example, the rate og oxidation of a magnesium alloy is represented by a rate constant k.
