Answer:
Answer 9 - 100 joules energy was at the producer level
Answer 10 - Remaining energy is used in metabolism
Explanation:
Answer 9
The energy at each trophic level is only 10% of the energy at its previous trophic level.
The energy at producer level is X
% of
Joules
Joules
Answer 10
Because the remaining 90% energy is utilized by the producer for its metabolism
Answer:
Mole fraction H₂O → 0.72
Mole fraction C₂H₅OH → 0.28
Explanation:
By the mass of the two elements in the solution, we determine the moles of each:
25 g . 1 mol/ 18g = 1.39 moles of water (solute)
25 g . 1 mol / 46 g = 0.543 moles of ethanol (solvent)
Mole fraction solute = Moles of solute / Total moles
Mole fraction solvent = Moles of solvent / Total moles
Total moles = Moles of solute + Moles of solvent
1.39 moles of solute + 0.543 moles of solvent = 1.933 moles → Total moles
Mole fraction H₂O = 1.39 / 1.933 → 0.72
Mole fraction C₂H₅OH= 0.543 / 1.933 → 0.28
Remember that sum of mole fractions = 1
Answer:
it states that the total mass of the products are the same as the total mass of the reactants in a chemical reaction.
Explanation:
Since the question is incomplete, the table has been searched in order to comply with the question.
Based on the table that I have provided, the order of increasing
depth from shallowest to deepest are the following; A,B,C,D,E. The reason that
this is the order to be chosen because the one responsible for making water
dense is the salt that is on the water and by that, the base is likely to sink
whereas the ones with less salt won’t be as thick compared those who have much
salt and will skim on its top.
