Answer:
a) Watch the attaccment
b) Ethyl bromide is more reactive than n-propyl bromid, and this more than neopentyl bromide. Ethyl bromide has less steric hindrance than the others, to SN2 reactions.
c) t-butyl bromide is more reactive than isopropyl bromide, and this more than ethyl bromide. t-butyl bromide structure stabilize the carbocation, better than the others.
Explanation:
Speed of SN2 reactions depends on steric hindrance, the less hindrance, the most reaction speed, meaning more reactivity. Then, those linear structures are more reactive to SN2 reactions.
In the other hand, speed of SN1 reactions depends on the stability of the carbocation formed. Structure with ramifications can stabilize better the carbocation, these structures are more reactive to SN1 reactions.
It was named Avagadro number for the reason that it was discovered by Amadeo Avagadro, it was named after his last name. The one who in reality initially evaluated the real number of particles in a given substance, was Josef Loschmid. Avagadro was a legal counselor who had an enthusiasm for it, and the reason the number is named after him was a direct result of a French physicist named Jean Baptiste Perrin. Perrin utilized the term as a result of Avagadro's enthusiasm for Brownian movement. What Avagadro had done was assembled everything that researchers had found to help clarify the varieties that existed amongst iotas and atoms. The mole unit is short for the German word molekulargewicht. It was to some degree an aggregate push to build up the idea. Every individual that is said to have found it, is an alternate individual, however these four individuals are the most pertinent
Answer:water erodes the earth by passing over rock and thinngs many times, as in a river, the water slowly washes away the rock turning it into sediment or silt.
Explanation:
The process of conversion of inorganic substance into organic substance in presence of light by autotrophs is known as photosynthesis
Autotrophs : the organism which can synthesize their own food
The inorganic substanc used by autotrophs is CO2 and water
This CO2 and water is converted to glucose in presence of light or chemical energy.
The reaction is
6CO2 + 6H2O ---> C6H12O6 + 6O2
Thus in the process O2 is released as by product
Density=mass divide by volume
density=1.5g/mL, V=50mL
1.5=Mass/Volume
1.5(50)=mass
Mass=75g
Hope this can help.
