Explanation:
btw i found that on google lol
Answer:
Following are the answer to this question:
Explanation:
In the given question an attachment file is missing, that is attached. please find the attached file, and the following are the description of the given points:
a. At 100 degrees in 100 mL 5 g is dissolved.
For, it required:
b. At 0 degrees 100 mL dissolve in 0.3 g.
So, the dissolve:
After refrigeration 0.12 g will still be dissolved.
c. After dissolving and freezing, precipitation can occur which would still be impure if the cooling is instantaneous. The added solvent was also too hard to recrystallize. The solvent was placed below its place of reservation.
d. Recovery percentage:
The melting point of acetanilide:
Found=109(medium)
Melting point error percentages:
<u>Given:</u>
Enthalpy change (ΔH) for SO3 decomposition = +790 kJ
Moles of SO3 = 2.1 moles
<u>To determine:</u>
Energy required when 2.1 moles of SO3 reacts
<u>Explanation:</u>
The decomposition reaction is -
2SO3(g) → 2S(s) + 3O2 (g)
Energy required when 2 moles of SO3 reacts is 790 kJ
Thus, for 2.1 moles of SO3 the energy requirement would be
= 2.1 moles SO3 * 790 kJ/2 moles SO3 = 829.5 kJ
Ans: 830 kJ are required when 2.1 moles of SO3 reacts.
Answer:
Attached below
Explanation:
Attached below is the required diagrams
From the attached diagram ; Compounds 1 and 2 are achiral ( i.e. stereoisomers aren't possible here )
Compound 3 : ( 1S, 2R ) - 1 - chloro-2-methylcyclopropane
Compound 4: ( 1R , 2S ) - 1- chloro-2-methylcyclopropane
Compound 5: ( 1R, 2R ) - 1 - chloro-2-methylcyclopropane
Compound 6: ( 1S, 2S ) -1- chloro-2- methyl cyclopropane
