order to compensate for the lack of supply of food the farmers need to somehow make their animals grow faster. For the solution they introduced the use of hormones. These hormones include estradiol‚ progesterone‚ testosterone‚ zeranol‚ trenbolone acetate and melengesterol acestate. Some of these hormones are found naturally in humans and some are synthetic growth promoters. But‚ is it safe for these foods to be consumed by people; and do they have any effects on our bodies? First‚ let’s define

Solvents used were water‚ methanol‚ n-butanol‚ ethylene glycol‚ acetone‚ hexane‚ toluene‚ ethyl acetate‚ and dichloromethane. Then added to the vials was 0.5 mL of isooctane in each one. The vials were then swirled and observed to determine solubility. In part two of the experiment‚ 0.5 mL of concentrated sulfuric acid was added into two sample vials

• The equilibrium law DYNAMIC EQUILIBRIUM forward A +8 reaction ""r=====~’~ reverse reaction Most chemical reactions do not go to completion. Once some products are formed the reverse reaction can take place to reform the reactants. In a closed system the concentrations of all the reactants and products will eventually become constant. Such a system is said to be in a state of dynamic equilibrium. The forward and reverse reactions continue to occur‚ but at equilibrium
