Answer: When the concentration of nanosilver particles in water is increased, the population of Daphnia magna will decrease
Explanation:
The statement below that is the most likely testable hypothesis based on the information provided is that when there is an increase in the concentration of nanosilver particles in water, the population of Daphnia magna will decrease.
Since we are informed that the particles may decrease survival in many aquatic organisms, it simply means that an increase in the particles in water will bring about the decrease in the Daphnia magna, which is the tiny freshwater crustacean.
I’m sorry but i don’t see an attachment of choices or anything
Answer:
Explanation:
There is a chemistry category, but:
find the ratio by dividing by smallest value:
find and balance chemical formula:
2 molO and 1 mol C is needed for a complete reaction, therefore the limiting reactant is the O
solve for CO2 using the mol of O
convert mol to g again
