SORC has sent some water samples to your lab. These samples have been collected from the Wafting River as it flows through Hometown. The lab has done some preliminary tests on the samples for various common river pollutants and for dissolved oxygen. The results are shown in Table 1. What problems can you identify in the water sample?

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

a corroding iron, if that's one of your choices
