concentration in the Dead Sea due to high evaporation and damaged aquatic life near the Great Barrier Reef caused by run-off from agricultural land. Eutrophication is caused by an excess amount of nitrate and phosphate in water bodies. It is usually caused by fertiliser run off and dumping of sewage going into waterways (basically human activity). Algal bloom is the direct result of eutrophication where suffocation of aquatic life and nutrient depletion may occur. Professionals may use a colorimetric

Combustion of Acetylene (ethyne) Rx: Back Why I don’t do acetlyene explosions in our lab.... Combustion of alkanes A quick review.... • Combustion reactions of alkanes consist only of C and H (hydrocarbon) • require O2(g) as a reactant • produce CO2(g) and H2O(g) and a large amount of energy!! Oxygen can be the limiting reagent which can lead to Incomplete combustion. For complete combustion of a hydrocarbon‚ oxygen must be in excess. If there isn’t sufficient oxygen‚ incomplete combustion occurs

He states that all matter is composed of eternal‚ indivisible‚ indestructible and infinitely small substances which cling together in different combinations to form the objects perceptible to us. The Greek word for indivisible is atomos. This theory gives birth to the atom. Democritus was a Greek philosopher who lived between 470-380 BC He is the Greek to whom the conception of the Atomic theory is attributed. Democritus proclaims the atom to be the
