Ase Ruth Alozie Chemistry Take home test May 4, 2013

In a laboratory experiment, a student reacted 2.8 grams of Fe (s) (steel wool) in excess CuSO4 (aq), according to the following balanced equation: Fe(s) + CuSO4 (aq) -> FeSO4 + Cu(S). When the Fe(s) was completely consumed, the precipitated Cu had a mass of 3.2 grams. Did the student’s result on this experiment verify the mole ratio of Fe(s) to Cu as predicted by the equation? Answer: yes, because the experiment result was 2:1

Calculate the mole ratio of Fe to Cu and explain

Ase Ruth Alozie Chemistry take home test May 4 2013 Statement: All experiment carried out by scientist in laboratory yield experimental results that are accurate. Scientist follows directions accurately and repeat experiments multiple times to ensure that all their result are correct. If an experiment is done correctly, the final product (actual yield) will be equivalent to the amount of the product expected to be produced (Theoretical yield) I agree with the statement above for various reasons. Since the beginning of time, people have tried to find out more about the world around them, wondering how and why things work. A scientist is someone who studies science. With an experiment, the scientist is trying to learn something new about the world, or explanation of why something happens. A scientist conducts research and performs experiments for the purpose of making new discoveries about the world and how it works. They may concentrate on a particular field of science, such as Biology, Ecology, or...
