If you've noticed that your car has thick smoke coming out of the exhaust pipe, it may be a sign that your engine needs some attention. Just like you can examine an animal's stool to get an idea of its health, you can pay attention to the quality of your car's exhaust to get an idea of what's going on inside the engine.
The word sulfur has old roots. It comes from the ancient Latin word for sulfur, sulpur, which later changed to sulphur, perhaps under the influence of the Arabic word for yellow, sufra.
Not really. Sulphur is an element. Sulphur that is mined or recovered from oil and gas production is known as elemental sulphur, or brimstone. Sulphur can be combined with other elements to form various compounds. Sulphur compounds, such as sulphuric acid, also are produced as a by-product of ferrous and non-ferrous metal smelting.
