When ethyl ether is heated with excess HI for several hours, the only organic product obtained is ethyl iodide. T/F
1 answer:
Answer:
True
Explanation:
Ethers react with HI to form the corresponding alcohols and alkyl iodides.
Similarly, ethyl ether react with excess of HI to form ethanol and ethyl iodide. But in the excess of HI as mentioned in the question, ethanol too undergoes reaction with HI to form ethyl iodide.
<u>Hence, ethyl iodide is the only product when ethyl ether reacts with excess of HI for several hours.</u>

Explanation:
a) The amount of heat released by coffee will be absorbed by aluminium spoon.
Thus,
To calculate the amount of heat released or absorbed, we use the equation:
Also,
..........(1)
where,
q = heat absorbed or released
= mass of aluminium = 45 g
= mass of coffee = 180 g
= final temperature = ?
= temperature of aluminium =
= temperature of coffee =
= specific heat of aluminium =
= specific heat of coffee=
Putting all the values in equation 1, we get:
80.30 °C is the final temperature.
b) Energy flows from higher temperature to lower temperature.Whenever two bodies with different energies and temperature come in contact. And the resulting temperature of both bodies will less then the body with high temperature and will be more then the body with lower temperature.
So, is our final temperature of both aluminium and coffee that is 80°C less than initial temperature of coffee and more than the initial temperature of the aluminum.
