Answer:
The percent yield of this reaction is 42.1 % (option B)
Explanation:
Step 1: Data given
Theoretical yield of beryllium chloride = 10.7 grams
actual yield of beryllium chloride = 4.5 grams
Step 2: Calculate the percent yield for this reaction
Percent yield = (actual yield / theoretical yield) * 100%
Percent yield = (4.5 grams / 10.7 grams ) * 100 %
Percent yield = 42.1 %
The percent yield of this reaction is 42.1 % (option B)
Answer: radiation
Explanation: we get radiation from the sun, because radiation is the transfer of heat, and that's what its doing is transferring the heat from the sun to our bodies that is mainly why we get dehydrated, and too much sun can be very bad and harmful to our bodies especially if there is no sunscreen present.

The shape of a sal crystal is a right parallelepipede (cuboid)
The formula for the volumen, V, is: V = area of the base * height = side 1 * side 2 * side 3.
V = 1.44 * 10^-2 m * 2.4*10^3 m * 7.4*10^-1m = 2.56*10^-5 m^3
hey there!:
In the case of ammonia, the hydrogen bond is formed using the lone pair present in nitrogen and the hydrogen having δ+ charge (due to bonding with electronegative N) of another ammonia molecule. Thus the inter molecular attraction increases which in turn increases the boiling point .
Option B is the correct answer.
Hope this helps!
