Electric generating plants transport large amounts of hot water through metal pipes, and oxygen dissolved in the water can cause a major corrosion problem. hydrazine (n2h4) added to the water avoids the problem by reacting with the oxygen: n2h4(aq) + o2(g) → n2(g) + 2 h2o(l) about 4 × 107 kg of hydrazine is produced every year by reacting ammonia with sodium hypochlorite in the raschig process:

56.16 gregor mendel was the first scientist to use statistics to analyze scientific data. before mendel's experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. after mendel's discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. this is an example of pls
