Determine concentrations of Ca2+, HCO3-, CO32-, and H2CO3. Examine the charge balance and comment on what else your neighbor might be doing.
Balanced thermochemical equation and enthalpy diagram, The decomposition of zinc carbonate, ZnCO3(s), into zinc oxide, ZnO(s), and CO2(g) at a constant pressure requires the addition of 71.5kJ of heat per mole of ZnCO3.
At 340 K, Kp = 69 for the reaction H2(g) + I2(g) ô€• 2HI(g). 50.0 g of HI is injected into an evacuated 5.00-L rigid cylinder at 340 K. What is the total pressure inside the cylinder when the system comes to equilibrium?
draw a lewis structure of the molecule and indicate the number of bonds and orbitals used in bonding. Show electron configurations of the central bonding atom in both the unhybridized and hybridized states.
Acetaldehyde is produced by the dehydrogenation of ethanol according to the following reaction: C2H5OH CH3CHO + H2 An undesired side reaction occurs, which produces ethyl acetate: 2C2H5OH CH3COOC2H5 + 2H2 In a pilot plant, the conversion of ethano..
Often reactions of tertiary alcohols or tertiary alkyl halides result in elimination reactions and not substitution reactions
