Aldehydes without alpha hydrogens undergo Cannizzaro reaction in strongly alkaline conditions. However trihaloaldehydes undergo haloform reaction under the same conditions. I wonder what might be the reason?

I2 + Cl2+H2O --> HIO3- + HCl

Suppose you were dissolving a metal such as zinc with hydrochloric acid.how would the particle size of the zinc affect the rat eof its dissolution?

hi every one this my qustiong I hope find the answer Consider the reaction ca(oh)2(s)----->cao(s)+h2o(l) with enthalpy of reaction ΔHrxn =65kj/mol

I don't mean to be anal about this but I've recently stumbled upon this topic over the holidays and I'm thoroughly interested. What I fail to understand is Order's of Reactions with respect to & . Can someone give me a well concise explanation of this with a good example, say the decomposition...
