What is the conductivity of salt? Describe the following types of corrosion and give a practical example of each: 1. pure chemical corrosion. 2. pure electrochemical corrosion. Sodium chloride (salt) is not corrosive. None the less, it commonly gets the blame for corroding metals. Explain how...

chemical reaction kinetics are calculated from initial rate studies. One reagent is held at an artificially high concentration so that the concentration is effectively constant, and the kinetic rates are calculated from the change in concentration of another reagent. Because of the impediments associated...
What is corrosion ? Describe the role of zinc in cathodic protection of iron. Can we use tin in place of zinc for this purpose. Give reason.
Corrosive (corrosion of table and hand) Acute toxicity (skull and crossbones) Hazardous to environment (dead tree and fish) Health hazard/hazardous to the ozone layer (exclamation mark) What are the 5 types of hazards? There are many types of hazards -chemical, ergonomic, physical, and psychos...
How does the number of atoms change during a chemical reaction? What are the parts of a chemical reaction? Corrosion is what type of chemical change? What happens to chemical bonds during chemical reactions? What is the chemical activity of a substance?
what corrosion really is?my teacher says it is disintegration and decaying of metals via chemical and more precisely redox reaction.so according to my teacher corrosion is the wearing away of a metal through a chemical reaction.my question is as corrosion is process of decaying,wearing ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Corrosion, on the other hand, is a chemical reaction where metal reacts with oxygen in air or water to form rust. Rust is an oxide substance that weakens metal components over time. Corrosion can occur indoors and outdoors and usually happens slowly over time unless environmental conditions are...
