The outermost electrons of the atom are either lost or gained by one of the atoms to the other. therefore the atom gains negative charge when gaining and positive charge when losing
Answer:
See explanation
Explanation:
The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.
Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.
However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.
Answer: I believe the answer is an earthquake.
Explanation: Sorry If I am wrong!
thunderstorms and heavy rain
Explanation:
The weather in a region with an incoming air mass made up of moist air is predominantly that of thunderstorms and heavy rain.
Moist air brings in rainfall and thunderstorms. They are peculiar and predominant in tropical regions of the world .
- A moist air is an air mass that is moisture laden or full of water vapor.
- They are usually formed where evaporation of water vapor from sea water is very high.
- The evaporated water is warmer and lighter than the surrounding air.
- By virtue of this, it moves inland and condenses to form massive rainfall accompanied by thunderstorm.

Answer:
i) 0,7 molH20/s
ii)11,2 g O/s
iii)1,4 g H/s
Explanation:
i) To find the molar flow rate of water, we just convert the mass of water to moles of water using its molecular weight(g/mol) and changing to the proper units (lb to grames and hours to seconds):
ii) Now we just consider the oxygen in the water stream (for 1 mole of water there is 1 mole of oxygen):
iii)Just considering the hydrogen in the stream (for 1 mole of water there is 2 moles of hydrogen):
