Tema [17]

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: 2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O

Explanation:

Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken. In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.

The balanced combustion reaction is,:

2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O
