Chromium

divided in two classes: macrominerals, present in abundant quantities in the body. Macrominerals are calcium, chloride, magnesium, phosphorus, potassium, sodium and sulfur.

cutting down the biodiversity of our planet. Like the other two effects of the urban sprawl, pollution is mainly caused by humans. It is a byproduct of burning coal because when coal is burned, it releases harmful chemicals like sulfur, lead, mercury, chromium, arsenic, and cadmium. These chemicals can cause sickness, chronic illness, and death to any organism that comes in contact with it. The catalytic converter that was discusses earlier is the fix we currently have for car emissions. Clean…

pollutants, hazardous toxins which are dissolved, other particles, suspended matters and sediments of varying size at different concentration levels and composition are present. Chemical or physical pollutants • Heavy metals, including mercury, lead, and chromium • Organic particles such as feces, hairs, food, vomit, paper fibres, plant material, humus, etc.; • Soluble organic material such as urea, fruit sugars, soluble proteins, drugs, pharmaceuticals,…

The primary ports of Madagascar are Toamasina and Mahajanga. Tourism also aids the economy of Madagascar. Minerals reserves found in Madagascar are of bauxite, graphite, limestone, chromite, and mica. Madagascar is the tenth largest producer of chromium ores. The primary energy supply comes from the use of firewood, charcoal, and sugar cane residue. Many of the roads and airfield of Madagascar are not paved which may impede on economic production. In 2000 there were only about 10 percent of the…

The metric system was introduced to australia to provide an easier system than the imperial system. The metric system is a base 10 system (all units are done by powers of 10). The imperial use more complicated bases. Metric eg; 1000 mm = 1m, 1000m = 1km (not confusing) Imperial eg; 36 inches = 1 yard, 1760 yards = 1 miles (confusing) Types of motion: Rotational-pg 141 (…
