include (3) (ginkba) a cake, (4) (thinebrag),
making (5) (spreecods) foods and (6)
(liandsturi) processes.
Chemistry turned from (7) (maleych) into a true science in the
1770s. Antoine Lavoisier experimented and convinced other scientists that the total mass of
the (8) (starcanet) always equals the total mass of the
(9) (dropscut). This is known as the law of (10)
(vonscertainot) of matter and another way to say it is that matter is not
(11) (dracete) or (12) (oydderts).
(13) (rosevailio) is considered the father of modern chemistry.
He experimented on (14) (shelfim) and on animals, and came up
with plenty of experimental data and ideas about (15) (boomsctui),
(16) (praisenorti), and (17) (bammetolis)
that were helpful in the (18) (molepedevnt) of the biochemistry,
medicine, and sports science of today. He also developed a system for naming, or
(19) (tramconluten), and got together with other scientists to write a
book about it and get everybody to use the system. The (20) (PUCIA)
system is in use today for naming chemicals on the system Lavoisier started.
Chemical reactions are written down using chemical (21)
(quaintoes) with (22) (lombyss) for elements and compounds. Written
in this form, it is (23) (reasie) to tell what is happening.
