Given the EÂ° values for two half reactions, you can easily predict the potential difference of the corresponding cell: simply add the reduction potential of the reduction half-cell to the negative of the reduction potential (that is, to the oxidation potential) of the oxidation reaction.
How to Melt Glass With a Torch. Glass melting has a long history, going back to approximately 3000 BC. In these early times, glass was melted to decorate vases. Glass is made up of silica, sodium carbonate and calcium carbonate. Most glass melts at 1400 to 1600 degrees Farenheit. Nevertheless, there are specialized glasses that will melt at as low as 900 degrees.
Best Answer: Soda glass is normal glass! it is the cheapest eg compared with pyrex glass for heat resistant ovenware. Strictly soda glass may be just sand and soda fused together.The soda makes the glass water-soluble, soft and not very durable. Therefore lime is added increasing the hardness and chemical durability and providing insolubility of the materials.
