I will be glad to help another with their chemistry problem. However there are some basic cultures to observe. The help is given as a friend so do not take the demanding approach. I expect you to introduce yourself in a friendly manner. Your name and where you are from will be welcome. SOme pointers are given below:

• Who you are and which country you are from.
• A student or from the commercial sector.
• If you want clarification about a lesson posted, refer to the topic and the lessons and state exactly what you do not understand.
• If it is a chemistry problem from your school or work, provide the background to your problem and state exactly the help you require. I would need to know how much you know and be able to deal with the depth you require.

All mails with the above information will receive a reply.
