(That means that there is no loss of kinetic energy during the collision.) That's because the SI unit of volume is the cubic metre, m 3 - not cm 3 or dm 3 with 1 m 3 = 1000 dm 3 = 1,000,000 cm 3 . So if you are inserting values of volume into the equation, you first have to convert them into cubic metres.

There is a subtle difference between the two statements that is easily illustrated with a simple analogy. In chemical terms, if particles collide with enough energy they can still react in exactly the same way as if the catalyst was not there; it is simply that the majority of particles will react via the easier catalyzed route.

If ...If you look back at the second stage of the primary alcohol reaction, you will see that an oxygen inserted between the carbon and the hydrogen in the aldehyde group to produce the carboxylic acid. If you look at what is happening with primary and secondary alcohols, you will see that the oxidizing agent is removing the hydrogen from the -OH group, and a hydrogen from the carbon atom is attached to the -OH.

Iodobenzene can be made from the reaction of benzene with iodine if they are heated under reflux in the presence of concentrated nitric acid, but it is normally made from benzenediazonium chloride solution. There is a simple reaction between the diazonium ions present in the benzenediazonium chloride solution and the iodide ions from the potassium iodide solution.

For simplicity, the page only looks at amino acids which contain a single -NH2 group and a single -COOH group.

As the atoms get larger down the group, the bonding pair is further from the nuclei and the strength of the bond should, in theory, decrease, as indicated in the figure below.

(BBC Radio 4 is found between 92 - 95 MHz!) If you have also looked at proton-NMR, the frequency is about a quarter of that used to flip a hydrogen nucleus for a given magnetic field strength.
