Lead dioxide has been studied for over 150 years as a component of the lead-acid battery. Based on first-principles calculations, we predict that by tuning the concentration of electrons in the material, through control of the defect chemistry, PbO(2) can be rendered from black to optically transparent, thus opening up applications in the field of optoelectronics.
Galena is a common and popular mineral for rock hounds. Its characteristic cubes, distinctive cleavage and high density make it easy to identify and a favorite in high school geology labs. The structure of Galena is identical to that of halite, NaCl. The two minerals have …
Lead can be prepared from galena [lead(II) sulfide] by first heating with oxygen to form lead(II) oxide and sulfur dioxide. Heating the metal oxide with more galena forms the metal and more sulfur dioxide. Write a balanced equation for the overall reaction by adding the balanced equations for the two steps.
Divalent lead has a strong affinity for inorganic ions containing oxygen (eg, carbonate) or sulfur (sulfide). Lead can also complex with electron rich ligands in many organic cmpd such as amino acids, proteins, and humic acid. Kayser, R., D. Sterling, D. Viviani (eds.). …

Wisconsin State Mineral Galena (Lead sulfide) (Lead Sulphide) Adopted on March 9, 1971. The state mineral became Galena at the same time red granite became the state rock, thanks to the proposal put fourth by the Kenosha Gem and Mineral Society in 1971. They wanted to promote awareness of Wisconsin's geology.
Editor's note: Some chemicals in this database contain more information than others due to the original reason this information was collected and how the compilation was accomplished. While working with material safety data sheets (MSDS), I found that manufacturers sometimes used obscure names for constituent chemicals and I didn't always have a good idea of what I was dealing with.
