Answer:
SN2
Explanation:
The first step of ether cleavage is the protonation of the ether since ROH is a better leaving group than RO-.
The second step of the reaction may proceed by either SN1 or SN2 mechanism depending on the structure of the ether. Methyl and primary ethers react with HI by SN2 mechanism while tertiary ethers react with HI by SN1 mechanism. Secondary ethers react with HI by a mixture of both mechanisms.
Dipentyl ether is a primary ether hence when treated with HI, the reaction with HI proceeds by SN2 mechanism as explained above.
Answer:
both are chemical changes
525L
Explanation:
Given parameters:
Volume to Temperature ratio = 1.75
Temperature = 300k
Unknown:
Volume of the gas = ?
Solution:
We must carefully analyze and comprehend the detailed description of this experiment:
It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.
This implies that the pressure in the vessel is constant
This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.
Mathematically;

V and T are the volume and temperature
Now we can solve the given problem;
= 1.75
Since temperature is given as 300K
Input the variables:
= 1.75
V = 1.75 x 300 = 525L

Answer:
Model 1 represents the old geocentric model of the solar system and Model 2 represents the newer heliocentric model of the solar system.
Explanation:
Model 1 has earth in the center, therefore it is geocentric. the geocentric model of the solar system is old. Nobody believes in it anymore because it is scientifically inaccurate.
Model 2 has the sun in the center, therefore it is heliocentric. This is the newer model of the solar system.
Physical Change because a new substance was not created and if it was a chemical change, a new substance would have to be created.
