Complete question:
Write the condensed formula from left to right, starting with (CH3)x where x is a number.
See attached image for the structure formula of the compound
Answer:
(CH₃)₂CHC(CH₃)₃ named as 2,2,3-Trimethylbutane
Explanation:
If we number the longest chain of the carbon starting from the left, we will observe that there are four carbons in the straight chain as shown in the image.
Starting from first carbon from the left of the carbon chain, at carbon number number 2, there two alkyl group, that is two methyl (CH3 is two). Also at carbon number 3, there are three alkyl group, that is three methyl (CH3 is three).
The condensed formula will be written as;
(CH₃)₂CHC(CH₃)₃
This compound is named as 2,2,3-Trimethylbutane, an isomer of Heptane
Answer:
B.sugar solution
Explanation:
A sugar solution is not a compound.
Rather, the solution is a mixture and an impure substance.
- A compound is composed of two or more kinds of atoms or elements joined in a definite grouping .
- The properties of the compound is distinct from those of the individual atoms that makes them.
- Sugar solution is sugar and water
- It is made up of two compounds not chemically combined.
Correct answer- B the electrons every two elements are arranged in energy levels: a maximum two electrons in the first level. ((( i thinkkk )))
Explanation:
The given data is as follows.
T = 298 K,
= -5645 kJ/mol
= -5798 kJ/mol
Relation between
and
are as follows.
=
-5798 kJ/mol = -5645 kJ/mol - 
-153 kJ/mol = -
= 0.513 kJ/mol K
Now, temperature is
= (37 + 273) K = 310 K
Since,
=
= 
= (-5645 kJ/mol - 159.03 kJ/mol)
= -5804.03 kJ/mol
As, change in Gibb's free energy = maximum non-expansion work

= -5804.03 kJ/mol - (-5798 kJ/mol)
= -6.03 kJ/mol
Therefore, we can conclude that the additional non-expansion work is -6.03 kJ/mol.
