Bette Nesmith Graham As electric typewriters came into widespread use after World War II‚ Bette Nesmith Graham and countless other secretaries let out a collective groan. The new machines did make typing easier‚ but their carbon-film ribbons made it impossible to correct mistakes neatly with a pencil eraser. As a result of this predicament‚ Graham ended up inventing one of the most widely used office products of the 20th century. Born in 1924 in Dallas‚ Texas‚ Bette Graham dropped out of high

Do Gas Stations cause soil pollution? Soils are extremely important parts of every ecosystem. They are a home to many microbes and provide vital nutrients to the plants that live in them. pH is the measure of acidity or alkalinity of a solution‚ and most organisms have a very small range of pH values in which they can survive. 7 is considered neutral‚ lower than 7 is acidic (lemon juice‚ rain water) and above 7 is basic (bleach‚ soap). Lots of urban areas are dependent on car transportation‚

The cost of gas is expensive enough and car companies are employing new tactics to alleviate most of the pollution that cars cause‚ by the use of electric cars‚ cars that have higher gas mileage‚ smaller cars‚ smaller engines and inspection regulations for each automobile to be done every year. As far as raising gas prices‚ I think that will cause more damage than good. People rely too much on transportation nowadays to make gas expensive. It would potentially put the

Lab #2 – Separation of a Mixture of Solids Abstract The mixed solution contained benzoic acid‚ iron‚ table salt‚ and sand. When separated using water‚ fuel‚ or a magnet‚ their characteristics and properties changed. The mass of the entire mixed solids was 6.6 grams. When the magnet was used‚ the iron was immediately picked up. The mass for that was 1.7 grams. The table salt was 1.2 grams. Benzoic acid mass was 0.8 grams and the sand was 1.4 grams after being separated. Introduction The objective
