Answer:
Explanation:
Isomerism is the occurrence of two or more compounds with the same molecular formula but different structures. Isomers with the same molecular formula and belonging to the same homologous series tends to have similar chemical properties but slightly different physical properties as a result of their constitutional (structural differences).
Thus,as the number of carbon atoms in a molecule increases , the number of isomer also increases. In the given question C7H16 is known as heptane which have nine (9) possible constitutional (structural) isomers.
The main objective is to provide the names for the constitutional isomers with the molecular formula C7H16.
In the attached file below; we've shown the possible isomers of heptane (C7H16). and we've identify them by naming them.
Answer:
D

Universe consits of galaxies, galaxies consit of solar systems, and solar systems consist of planets
The subscript for H in the empirical formula for this compound is 3.
There are 3 steps involved in the construction of empirical formula.
Calculation of empirical formula is as under as ...
Step 1: Divide the % of each atoms which their atomic weights.
C = 51.27 / 12 = 4.27
H = 7.75 / 1 = 7.75
O = 40.98 / 16 =2.56
Step 2 : Divide all the answers with the smallest answer to get the subscripts for empirical formula.
C = 4.27/ 2.56 ≈ 2
H = 7.75/ 2.56 ≈ 3
O = 2.56 /2.56 = 1
Step 3: Construction of empirical formula by putting subscripts calculated in step 2.
Empirical formula form given data = 
Thus , subscript for H in the empirical formula for this compound is 3.
