The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges.
The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds.
Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas
The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.
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:
plants take carbon dioxide out of the atmosphere and use the energy from sunlight to combine the carbon dioxide and water to form sugar and oxygen
Answer:
I think it's light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change
You have to move the decimal point forward 2 times to make the number 3.4,which makes the scientific notation 3.4×10^-2
