Lab Report 1 Introduction: Proper chemical formulas entitle many challenges such as the Law of Multiple proportions that states that there may be more than one plausible mole ratio for the elements in that compound. However if we determine the mass of each element in the compound we will be able to get the true chemical formula. In this experiment‚ we used the law of definite proportions to find the chemical formula for a hydrated compound containing copper‚ chlorine‚ and water molecules

Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

Lab Report 1: Natural Selection Introduction: In today’s lab we learned how natural selection and survival of the fitness took place in Darwin theory by testing it out with four different utensils which were Spoon‚ Fork‚ chopstick‚ and clothespin which represent the four different types of bird beaks. Our goal was to see which one utensil ( bird beak) would outcome the other four utensil ( bird beak) by being able to survive with the limit amount of food‚ the environmental chances‚ and see who

The purpose of this lab was to understand that because substances have different properties‚ such as mass‚ that can be separated by chromatography. In our experiment‚ we chose 4 different color source to separate in water. We made sure that all the sources were water soluble because only polar substances will dissolve in water. We chose a black wet-erase marker‚ a red marker‚ a green marker‚ and mixed food coloring to test. The chromatography paper was split into 4 sections‚ about 2 cm above the

Journal: Grandmothers as Replacement Parents and Partners: The Role of Grandmotherhood in Single Parent Families Lone parent families have long been analysed and researched by how they function and how children from these families are affected and develop. Drawing on a research paper from the Journal of Intergenerational Relationships‚ Harper and Ruicheva (2010) discuss the increasing significance of grandmothers’ involvement and frequent adaptions to becoming replacement partners and parents within
