Answer: A. Diethyl ether has a very low miscibility in wate
The fact that the diethyl ether is miscible or not in water <u>does not imply a ris</u>k for the person who is working with this reagent in the laboratory.
However, the fact that diethyl ether forms explosive peroxides and that it is highly flammable implies that there is a risk of explosion when exposed to air and sunlight. On the other hand, as option C mentions, if a person inhales a large quantity of this reagent, they may lose consciousness and suffer some injury when fainting, due to the powerful anesthetic effect of this reagent.<u> In conclusion, options B, C and D are statements that imply safety problems associated with the use of diethyl ether in the laboratory, while option A does not imply it.</u>
It should be increasing the rate of the forward reaction will cause a shift to the left because the external stress, which is the increase in rate, will cause the reaction to be unbalanced, and to reach equilibrium it needs to shift to the right.
Answer:
The mass of ammonia (NH3) that contains 
hydrogen atoms is 
g.
Explanation:
As 
atoms of hydrogen = 1 mole of the hydrogen atom
Therefore, 
atoms of hydrogen 
moles of the hydrogen atom.
Now, there are 3 moles of hydrogen atoms in 1 mole of ammonia 
.
As the mass of 1 mole of ammonia is 17g, so
when there are 3 moles of hydrogen atoms, then the mass of ammonia = 17 g
Therefore, when there are 
moles of hydrogen atoms, then the mass of ammonia 
g.
Hence, the mass of ammonia that contains hydrogen atoms is g.
