Answer:
Ethanol
Explanation:
Hello,
Since the hexanes and the ethyl acetate are mostly composed by C-C, C-H and for the ester C-O bonds which are apolar, just the ethanol which has one O-H bond could be classified as polar, allowing H-bridges to be present.
Best regards.

Answer:
44,55 can be produced.
Explanation:
First, we balanced the equation
1Cu + 2AgNO3 → 1Cu(NO3)2 + Ag
Then, we find the moles of each reagent
Now, we find the limiting reagent from the quantities of product that can be formed from each reagent
1,086 moles of AgNO3 is necessary for each mole of Cu since we have 0.413 moles of Ag(NO3), the nitrate is the limiting reagent
the value of the limiting reagent determines the amount of product that is generated
∴ 0,413 mol of Ag can be produced
Ag = 
= 44,55g
Ag≈ 44,6g
Answer:
ecosystem:a biological community of interacting organisms and their physical environment.
rainforest: a luxuriant, dense forest rich in biodiversity, found typically in tropical areas with consistently heavy rainfall.
major part of rain forest:Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation.
coral reefs :a ridge of rock in the sea formed by the growth and deposit of coral.
type of coral reefs:fringing reefs, barrier reefs, atolls, and patch reefs

Answer:
W = -25 J
Explanation:
For a cyclic process, the variation of internal energy (ΔU) must be 0. It means that ΔU from step 1 must be equal to ΔU from step 2. For the first law of the thermodynamics, the energy must be conserved, so:
ΔU = Q - W, from each step. Q is the heat and W the work
When the heat is gained by the system, the process is endothermic, so Q >0, when the system loses heat, the process is exothermic, and Q<0. When the system is expanding W>0, and when it is compressing, W<0.
From step 1:
ΔU = 42 - 14
ΔU = 28 J
From step 2:
28 = -53 - W
W = -53 + 28
W = -25 J
