Can an alkyl shift to cause a ring expansion ever start a SN1/E1 process even before carbocation formation?
A certain second-order reaction (B-> Products) has a rate constant of 1.80×10^-3 M^-1xs^-1 at 27C and an initial half-life of 216 s . What is the concentration of the reactant B after one half-life?Express the molar concentration numerically.
Consider the coordination of Cu2+ by the tridentate iminodiacetate ligand . When the monoprotonated form, , abbreviated HA , is added to an aqueous solution of Cu2+,
A single pulse of a laser yields an average of 5.00 × 1018 photons with λ = 633 nm. If melting ice to water at 0°C requires 6.01 kJ/mol, what is the fewest number of laser pulses need to melt 10.0g of ice?
Three manufacturers are producing carbonated bottled water. One company introduces carbonate by bubbling carbon dioxide into water until
Write the correct equation for the ready formation of a metallic deposit on placing a Ni(s) strip into 0.1 M copper nitrate.
If 4.10 mol calcium carbide (CaC2) reacts with an excess of water, how many moles of acetylene (C2H2) will be produced?
The equilibrium constant at 427°C for the reaction N2(g) + 3H2(g) 2NH3(g) is Kp = 9.4 × 10-5. Calculate the value of ΔG° for the reaction under these conditions.
Suppose that 0.92 of water condenses on a 85.0 block of iron that is initially at 22. 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 ..
If you are given a thermometer with 10 divisions between 10.1 and 10.2 degrees Celsius, and room temperature is exactly 22 degrees Celsius how should you report that value
The generic metal hydroxide M(OH)2 has Ksp= 6.64x10^-18. (Note: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH from water can be ignored. However, this may not always b..
