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

Though‚ may I might add‚ the tale is still epic in a timeless sense‚ ‘Spearesy’ uses small-scale settings and conversations to say a thing or two about morality and its effect on life and lives. “ ‘Murder most foul‚ as in the best it is; but this most foul‚ strange’‚ ‘Haste me to know’t‚ that I‚ with wings as swift As meditation or the thoughts of love‚ May sweep to my revenge’ “.

advancements in all aspects of life whether it be scientifically or creational (creatively). Technology is part of every person’s life and without it we wouldn’t be able to move forward. So why do we want to move back? Although many of us are for technology and the new scientific and social developments that come with it but there are others that are not so fond of it and complain that technology is taking over our lives and some people argue that technology may be the cause of our lack of social skill
