NH3 has a bond angle of 107 degrees and is pyramidal this is because it has 3 bonded pairs and 1 lone pair. the lone pair repels more than the bonded pairs and this results in the bond angle being 107 deg...

This is to do with the definition of a transition metal (TM). A TM is a metal which loses electrons to form an ion with an incomplete D subshell. Scandiums most stable ion is a Sc3+ ion losing both the el...

The forward reaction in the Harber process is exothermic. Following Le Chatelier's principle, the reaction would therefore be favoured by using lower temperatures, increasing the yield of ammonia at equil...

Benzene consists of a ring of 6 carbon molecules. Each of these carbon molecules are bonded to each other by single bonds. This leaves free electrons in p-orbitals. The p-orbitals overlap, creating pi-bon...

The element carbon can exist as a few different "isotopes" - all this means is that the number of neutrons in the nucleus can vary to give atoms that behave the same way chemically so are still ...
