Laying hens have a high demand for calcium‚ especially during egg production when calcium output is at its greatest (Scott et al‚ 2002). Complete Randomized Design was used to find out the effect of Chicken (Gallus gallus domesticus) eggshells in the mass of the chicken layers. There were five

Macroscale and Microscale Organic Experiments ( 6th edition pp. 531-534) Belmont‚ CA: Brooks Cole. Purpose: In this experiment‚ potassium carbonate combined with a quaternary ammonium salt to form a strong base. The strong base created an anion from an ester of malonic acid. The ion reacted with bromobutane which was also in the reaction solution to give the product. The yield product was a

Chloride salts are the source of hydrogen chloride that is evolved during distillation. Magnesium chloride is the most prolific producer of HCI with calcium chloride and sodium chloride ranking second and third‚ respectively‚ in HCl production. As the concentration of a chloride decreases‚ the evolution rate diminishes

When burning the splint is placed on the test tube‚ the flame is extinguished.
