Answer:
The BOD5 for this sample is 5 mg/L
Explanation:
The BOD5 takes into consideration the difference between the initial DO and the final DO divided by the fraction of the sample tested in a 300 mL BOD flask. The problem states that the sample was directly placed in a BOD bottle so we assume that the volume used was 300 mL of the water sample. The fraction of water is 1 (300/300).
BOD5 = (10-5)/1
BOD 5 = 5 mg/L

<u>Answer:</u>
<em>The two primary factors that impact how a well of lava will eject are consistency and gas content. </em>
<u>Explanation:</u>
<em>Both are identified with the arrangement of the magma. </em>Hawaiian volcanoes will in general emit basalt , which is low in consistency and low in gas content (about 0.5 weight percent).
The higher the level of silica substance of magma, the more thick it is. <em>Since a magma with less silica substance is moderately liquid and has a high capacity to stream (low consistency)</em>
