Chemistry of today
Chemistry of today is so extensive that it is divided into 5 branches to explain it:
Organic chemistry: molecules studied by carbon chains.
Inorganic Chemistry: study minerals and elements from the periodic table.
Analytical chemistry: study the composition of matter in qualitative and quantitative.
Biochemistry: study the composition of the six living.
Physical chemistry: studies matter from the point of physically and chemically. -
Scientific method
Is a research method used mainly in the production of knowledge in science. For being called scientist, a research method should be based on the empirical and measurement, subject to the specific principles of scientific method testing is razonamiento. The cientific method, that has characterized much, consists mainly in systematic observation, measurement, experimentation, formulation, analysis and modification of hypotheses. -
