Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different.This causes almost opposite characteristics in their physical properties. Graphite is rather common mineral, but fine crystals are rare.Most Graphite mining areas produce enormous quantities from a single or several large Graphite vein s, but collector specimens in good crystals are not commonly encountered.raphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different.
A , Cardiology (Cardiovascular Disease), answered. Blood is pumped into the lungs by the right lower chamber of the heart, called the right ventricle. It then returns to the left upper chamber, called the left atrium, and flows into the left ventricle, which pumps it to the rest of the body.
deoxygenated blood comes into the right atrium, then to the right ventricle of the heart. From the right ventricle it is pumped to the lungs where it becomes oxygenated. Once oxygenated, it returns to the left atrium and then moves to the left ventricle. From the left ventricle it is pumped to the rest of the body.
