examples of chemical transformation that you use in your daily activities?

Tums is a great example... By mixing with the acid in your stomach, it neutralizes the acid, causing it to form water, and a salt(not the same as table salt).  Everytime you breathe it's a chemical transformation as the hemoglobins pick up the oxygen from your lungs, and carry them throughout your body.

chemical reactions are the basis for life on this planet, and the fact that everything in the world that we know of realtes to chemistry it carries a very high importance in understanding the world around us. The greater understanding of the world the better the chance that we can manipulate the world to suit our needs and desires.

Typically you can do most regular organic chemistry reactions with radiolabelled substrates. So for instance\n\nacetaldehyde + NaT4 -> CH3CTHOH\n\nCH3CTHOH + Na(129)I -> CH3CTH(129)I would work

A hydrocarbon where some of the hydrogens have been replaced with alkyl side-chains or other elements (e.g. halogens, oxygen-containing, or nitrogen-containing groups)

enzymes in our body are chemical reactions catalyst's like saliva for example which helps us to decompose large sugar molecules...other examples are the catalyst's that make food ferment and we use it in wines and old cheeses or Yakult (fermented milk) yogurts and other products

single replacement, for example: CO2+N3=CN3+O2

NaHCO3(s) + CH3COOH(aq) → CH3COONa(aq) + CO2(g) + H2O(l) \nThis is the real chemical reaction.

using letters to represent the general situation for a replacement reaction you'd get:\n\nA  + B-C react to produce B + A-C. In other words molecule A was by itself in the beginning but it replaced B to form a new molecule and molecule B ends up by itself.

Functionallizing the EDTA to make a substituted EDTA

Lucas Reagent replaces the OH group by a Cl group.\nTherefore CH3-C5H8-OH + HCl -> CH3-C5H8-Cl + H2O

1a.) So you do not end up with more of one element than you started out with, elements cannot be created or destroyed in chemical reactions\n1b.) in a physical change, the elements do not combine with other elements- it remains the same substance (i.e. cutting paper or melting ice) a chemical change happens when chemical properties are changed, and new substances are formed (i.e. burning, baking soda and vinegar)\n2.) organic compounds an be found in living things, soil, or near anywhere living organisms are.\n3.) Carbon, Hydrogen

A synthesis reaction is when you start off with 2 substances and end up with 1:\nA+B--->AB\n\nFor example \n\nanhydrous copper (II) sulfate + water --> copper sulfate pentahydrate\nCuSO4 + 5H2O  ---> CuSO4* 5H2O\n\nIn this reaction, the color changes from white to blue. So the color change is the evidence.

Apparently groups in Sweden, Australia, and the UK are working on this. There are probably others as well. They are making progress. It does appear that this might allow the industrial scale separation of water into hydrogen and oxygen, and the reduction of atmospheric CO2. \n\n\nRecently, Jim Barber and So Iwata of Imperial College in London identified the actual crucial molecules that are used to split water by plants. This might lead to huge advances eventually. It is quite exciting.
