So far we have only studied simple mixtures.in our natural environment,substances usually in the sense that there are several compnents.
for example.air is a mixture of gases-oxygen,nitrogen,arg0n,and the other gases that are usually released by the activities of human beings or are products of technology.if such gases are present in am0unts that…[Read more]
