Answer:
See explanation and image attached
Explanation:
Aromatic hydrocarbons undergo electrophillic substitution. Usually, substituted benzene is more or less reactive to electrophillic substitution compared to unsubstituted benzene.
Substituents on the benzene ring tend to direct the incoming electrophile during electrophillic substititution. The presence of the -CH3 group on toluene directs the incoming Br electrophile to the ortho/para position.
Where the incoming electrphile E is Bromine, we can see that in the ortho/ para product, the electron pushing -CH3 stabilizes the resonance structure formed and increases electron density at the ortho/para position via resonance compared to the meta product as we can see from the image attached. Hence, the ortho and para products predominate over meta products.

Just use a solubility chart! Find the cation on the far left and the anion on the top and find where they connect. If it says "s," it is not soluble. If it says "aq," it is soluble. Here, ZnF (Zinc Fluoride) is soluble. Hope that helps! :)
P.S. Not all of the compounds above are on this particular chart. In future problems, just google "solubility chart" until you find one with all of the compounds you need to look at.
Answer:
16.5moles of CO2
Explanation:
Molar mass of O2 is 32g/Mol
No of mole = 880/32 = 27.5 moles
27.5 Mol of O2 gives X mole of CO2
5 mole of O2 gives 3 moles of CO2
No of mole of CO2 = (27.5×3)/ 5 = 16.5moles
Answer:
Some of the orbits are nearly circular, while the moons farthest from Jupiter have more irregular orbits. The outer moon's orbit in the opposite direction in which Jupiter spins, which is unusual and indicates the moons were asteroids that were sucked into Jupiter's orbit after the initial system was formed.
