accessory factors in addition to proteins‚ carbohydrates‚ fats‚ minerals and water. Then‚ in 1912‚ thee chemist Casimir Funk identified that the antiberiberi substance in unpolished rice was an amine (a type of Nitrogen-containing compound)‚ so Funk proposed that it be named vitamine‚ from vital amine. It was later discovered that different vitamins have different chemical properties. This discovery caused vitamine to be turned into vitamin. In 1912 Hopkins and Funk made a hypothesis

THE PROBLEM AND REVIEW OF RELATED LITERATURE AND STUDIES Introduction Everyone is naturally pre-determined to have an offspring. This would just exist in a relationship of a man and woman. It is not always true in a relationship if there is a new life that will be formed. Several factors may contribute to the hindrances in the formation of new life especially to man because male (sperm) gamete is the one responsible to initiate fertilization‚ the union of male (sperm) and female (ovum) gametes

Synthesis Procedure 1 -1.0 Introduction A Cobalt-Amine-Halide compound is synthesized from cobalt (II) chloride hexahydrate. An orange-tinted solid is produced and is considered to be unknown since the specific ligand amounts are unknown. By determining the percent composition of various elements and compounds in the unknown‚ its true identity can be predicted. Chloride‚ ammonia‚ and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns
