Provide the name(s) for the constitutional isomer(s) with the molecular formula C7H16 that have an unbranched chain. If there is
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.

If the reactants of wood when burning weigh 10 kgs, how much will the products weigh?
aksik [14]

Answer:

the weight of products is is equal the weight of the wood plus the weight of oxygen that was used to burn that wood, so weigh of the product is greater than 10 kilograms.

Explanation:

Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.

In this example wood (mostly carbon) and oxygen are reactants and carbon dioxide (mostly) is product of reaction.
