Meausre the mass of two nails of each kind. Put the nails into the testtubes. For the series of 'Immersed', fill the testtube half with tab water and measure the total masses.

For the seiries of 'Dry', wrap a small amount of calcium chloride with a piace of tissue, and then put the tissue into the mouth of the testtubes. Allow the testtubes to rust for two weeks. After two weeks, mesuare the change in the mass of each nail.

Calculate the rates of each nail's rusting by dividing the the changes in mass by the time day. Purpose of the Experiment to know how to measure a reaction rate.

Chemistry of Rusting Iron. Rust is a general term for iron oxides formed by the reaction of iron with oxygen. Several forms of rust are distinguishable visually, and form under different circumstances. Rusting is the common term for corrosion of iron and its alloys, such as steel.

Although oxidation of other metals is equivalent, these oxides are not commonly called rust. Pure, solid iron oxidizes in water: This leads to the formation of OH- ions in cases where the body of water is significantly large, the pH does not rise as sharply, but this is of no consequence since OH- ions are always present, even in pure water.

In water with limited dissolved oxygen Fe3O4 s is formed, which is a black solid and commonly called lodestone:After my post on my son’s first job, I reached out to a few friends to hear from them about their high school work initiativeblog.comor Allison Fultz, a lawyer at Kaplan Kirsch Rockwell, wrote that she.

Grades Nine Through Twelve 3. g.* Students know how to identify reactions that involve oxidation and reduction and how to balance oxidation-reduction reactions. Prerequisites At least 9 units of Level III Pure Mathematics courses at credit standard or above and a strong background in Computer Science.

Restrictions Available only to students admitted to a relevant Honours program Course Description Students are required to take 5 courses and a research. Aug 27,  · So I'm thinking of just doing pure coursework, taking the comprehensive final and getting it over with in 2 years.

I could also do research as an elective, but just not write a thesis, so there's no time pressure.
