Chemical equations may be either unbalanced or balanced. An unbalanced chemical equation doesn't account for conservation of mass, but it's often a good starting point because it lists the products and reactants and the direction of the chemical reaction. As an example, consider rust formation....

Write the chemical components of the reaction in the standard notation format. In our example, this will be CH4, O2, CO2 and H2O. In chemistry, to "yield" means that whatever is before turns into whatever comes after, so be sure that "yield" is roughly in the middle. That phrase will...
Describe the difference between chemistry and chemical technology. Discuss some of the healthcare applications of chemical reactions. Two substances are mixed together. Explain how the observer could determine if this reaction is just a mixture or an actual chemical reaction. Give an example of ...
China's scientific and technological progress earned similar recognition. For example, the research team where Evans works now has advanced equipment that is worth tens of millions of dollars in their state key lab, which, two decades ago, was just a rudimentary facility. The team has grown fro...
