1.5 % is the percent yield in the reaction.
Explanation:
Given that:
original mass of the sample used in reaction = 1.897 grams
product formed after decomposition = 1.071 grams
The reaction for the decomposition:
Mg(HCO3)2 (s) ⇒ CO2 (g) + H2O (g) + MgCO2 (s)
It says that 1 mole of Mg(HCO3)2 yielded 1 mole of MgCO2 on decomposition
68.31 grams/mole or 68.31 grams of MgCO2 is formed
percent yield = x 100
putting the values in the equation:
percent yield =
= 0.015 x100
PERCENT YIELD = 1.5 %
Answer: Option (d) is the correct answer.
Explanation:
Carbon tetrachloride is a non-polar solvent. Whereas out of the given options,
,
,
, and HI are all polar molecules.
On the other hand, only is non-polar molecule.
Also it is known that like dissolves like.
So, being non-polar will dissolve the give alkane,
