Explanation:
Make sure to check for sig figs though. Basically, you have 2.54 mL and you multiply that by the 0.789 g/mL and mL cancels out and you are left with 2.00406g. There are 46.06844 grams per mol of ethanol, so to cancel out grams we multiply by 1/46.06844. And then we are left with 0.04350179862 mol
A it increases is the correct answer.
Good luck and I hope this helps.!
Answer:
Fecal coliform increases the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.
Explanation:
Fecal coliform are species of bacteria that are found in the intestine of warm-blooded animals like humans etc. Hence, they are released whenever they excrete feaces. Due to this reason, the presence of fecal coliform bacteria in a water body indicates fecal discharge into that water.
The presence of excessive fecal coliform in a water body increases the amount of organic substances in the water. These organic substances are decomposed by bacteria, which causes the oxygen present in the water body (dissolved oxygen) to deplete/decrease. The depletion of oxygen in the water threatens aerobic aquatic organisms e.g fishes and they ultimately suffocate and die.
