anode. My experiment is aimed at testing the corrosion of 2 different types of nails in a certain molar solution of salt water in anticipation of determining which of the two would be more suitable for beachside residencies. I hypothesized that the iron nails would almost double in content of rust as the molarity of the solution they’re soaked in increases. The galvanized nails hopefully will end up with limited amounts of rust in all solutions. The activity series plays a major role in corrosion

Ukraine is rich in natural resources: coal‚ iron ore‚ manganese‚ nickel and uranium‚ and others. The reserves of sulfur are the largest in the world‚ the reserves of mercury ore are the second largest. Also more than 5% of world reserves of iron ore are concentrated in Ukraine. There are oil and gas deposits but their reserves are not significant (the reserves of these fossil fuels were partly depleted during the Soviet period). Coal is the main fossil fuel of Ukraine. It is mined in the Donetsk

The hydrochloric acid was a clear liquid that looked like water It weighed 42.2 grams in total. During the reaction‚ the two substances produced bubbles‚ creating smoke and became warm with a smell that is irritating to the human nose. After the reaction‚ it appeared to be a clear‚ bubbly

Determination of Manganese in Steel Submitted by: ------------------- Date of Submission: 27.03.11 Objectives: In steel production aside the iron‚ which is the primary source‚ some amounts of manganese is used together with carbon. The objective of this experiment is determining the manganese amount in the steel compound by using UNICAM UV-VIS Spectrometer. Theory: Many molecules absorb ultraviolet or visible light. The absorbance of a solution increases
