Define in common language, with appropriate instance the role played by redox-type reactions in the formation of photochemical smog.
In a haloform reaction with chloride, what reaction step is pertinent to the synthesis of molecular chloride?
The rate law for the reaction, 2NO(g) + O2(g) -- 2NO2(g), is found to be: rate of reaction=k[NO]2[O2]2 (PLEASE note that the 2's after the concentrations are powers, so we have NO to the power of 2 and O2 to the power of
Write down the product for the reaction; Butane (forward and backward reaction)in the presence of Aluminium bromide and HBr at the temperature of 27 degree celcius/
When 0.0024 moles of a weak acid are dissolved in enough water to make 0.500 L, the pH of the resulting solution is 5.28. Calculate Ka.
Calculate ?Sºf for oxalic acid and ?Sº for the combustion of one mole of oxalic acid. c) Calculate ?Gºf for oxalic acid and ?Gº for the combustion of one mole of oxalic acid.
Aspirin (acetylsalicylic acid,C9H9O4 ) is a weak monoprotic acid. To determine its acid-dissociation constant, a student dissolved 2.00g of aspirin in 0.600L of water and measured the ph. What was the Ka value calculated by the student if the pHof..
A piece of metal of mass 22 g at 92C is placed in a calorimeter containing 53.7 g of water at 21C. The final temperature of the mixture is 55.3C. What is the specific heat capacity of the metal?
Use MO theory to predict the net bond order after N2 interacts with a photon that results in the promotion of an electron from bonding to an antibonding orbital.
