Problem- Give two definitive examples of tunneling in chemistry (as opposed to physical process). Of course, "definitive" implies that the process must be observable. Explain your answer in detail.
Kindly Please put your best effort to provide the solution of above problem
Draw the structure of hydrocarbon that reacts with 2 equivalents of H2 on catalytic hydrogenation and gives only succinic acid on reaction on acidic KMnO4
Calculate delta H rxn for the reaction MnO2(s) + 2C(graphite) ---> Mn(s) +2CO(g) from the following information: Mn(s) +O2(g) ---> MnO2 delta H = -520.03 kJ 2C(graphic) + O2(g) ---> 3CO (g) delta H = -221.04 kJ
Problem- By titration, 15.0 mL of 0.1008 M sodium hydroxide is needed to neutralize a 0.2053 g sample of a monoprotic acid. What is the molar mass of the acid
Which of the following types of radiation is composed of particles with a charge and mass identical to that of an electron?
The reaction caused the temperature of the solution to rise from 23.27 °C to 27.49 °C. If the solution has the same density and specific heat as water, what is PH for this reaction per mole of H2O produced. Presume that the total volume is the sum..
A solution of a specific vitamin has ?max = 273 nm and a concentration of 6.51 × 10-7 M. The absorbance of the solution at 273 nm is A = 0.180. What is the molar absorptivity of the vitamin at 273 nm? (sample pathlength = 1.00 cm)
If the heat released during condensation goes only to warming the iron block, what is the final temperature (in ) of the iron block. (Assume a constant enthalpy of vaporization for water of 44.0.)
what percentage of HSO4- is dissociated in 2M solution? Why does molarity approximate molality at low concentrations?
The active ingredient in some antiperspirants is aluminum chlorohydrate, Al2(OH)5Cl. Analysis of a 2.000-g sample of antiperspirant yields 0.334 g of aluminum. What percent (by mass) of aluminum chlorohydrate is present in the antiperspirant?
draw lewis structure for pcl3. calculate the formal charge on p. what is the name of geometry for the molecule? is the
The atomic absorbances were measured as 0.105 and 0.201 for Ti and Co respectively. As a reference, a standard mixture containing 2.14 g Co/mL and 1.27 g Ti/mL was prepared as well as measured to have a signal-to-signal ratio of 2.53 Ti: 1.00 Co. ..
