Copper in Silver Nitrate Lab: Making Silver Sabrina Kate S. Carranza – Chemistry Hour 6 I. Purpose: The purpose of this experiment is to distinguish the relationships between reactants and products‚ in addition to expanding on concepts such as single displacement reactions‚ mole ratio values‚ moles to mass‚ theoretical yields‚ limiting reactants‚ excess‚ stoichiometric relationships and percentage errors. II. Hypothesis: /3 -If the copper metal is submerged in the silver nitrate solution

I believe that Copper Sun should be taught to future generations because it is an inspirational and informational novel. This novel instructs us about a dark time in our history‚ and how if we want it not to repeat itself‚ we should advice future generations to prevent that from happening again. Copper Sun is an exceptional good read. The book teaches us multiple lessons about how you should always persevere through the difficult times just like the two main characters in the book‚ Polly and Amari

Quantitative Research Methods Quantitative means quantity which implies that there is something that can be counted. Quantitative research has been defined in many ways. It is the kind of research that involves the tallying‚ manipulation or systematic aggregation of quantities of data (Henning‚ 1986) John W. Creswell defined quantitative research as an inquiry into a social or human problem based on testing a theory composed a theory composed of variables‚ measured with numbers‚ and analysed with

this is the affected variable. Then the X-axis is the independent variable which affects the other variable (Argyrous‚ 2005). Once the scatter graph has been plotted the direction‚ correlation and the strength of the correlation can be analysed. Analysis becomes a lot more intensive after the data has been collected (Thomas‚ J.R‚ 2005). The correlation can be positive or negative and is represented as a numerical figure. This decimal figure ranges from -1 to +1 (Hosker‚ 2008) When the figure is
