Combination: Joining of two different substances to form a more complex substance.
Decomposition: Breaking of a compound into two or more products.

Answer:
Alcohols effectively inactivate non enveloped viruses by attacking lipids.
Explanation:
Antimicrobial agents are the chemicals use to kill or stop the growth of the micro organisms. These antimicrobials can be applied on the living tissue and works against specific microbes.
The alcohols is used as an antiseptic that can protect the organisms from harmful microorganisms. The alcohol cannot inactivate the virus by attacking lipids as non enveloped virus do not have any cell membrane made of the lipids.
Thus, the correct answer is option (1).
A physical change can happen without changing any of the characteristics, for example if you have an ice cube which is frozen H2O and you let it sit it will melt only changing the physical appearance and the molecules in the substance. A physical change doesn't change the physical composition.
Answer: Octet rule
Explanation: The elements which have filled s and p orbitals or noble gases are most stable and thus every element tends to get stable by completing their octet.
For example: Sodium [Na] has atomic no of 11 and thus the electronic configuration is :
tends to get stable by losing one electron and gets converted to ![Na^+](https://tex.z-dn.net/?f=Na%5E%2B)
Electronic configuration for ![Na^+:1s^22s^22p^6](https://tex.z-dn.net/?f=Na%5E%2B%3A1s%5E22s%5E22p%5E6)
Thus acquiring stable configuration with filled s and p orbitals.
For example: Fluorine [F] has atomic no of 9 and thus the electronic configuration is :
tends to get stable by gaining one electron and gets converted to ![F^-](https://tex.z-dn.net/?f=F%5E-)
Electronic configuration for ![F^-:1s^22s^22p^6](https://tex.z-dn.net/?f=F%5E-%3A1s%5E22s%5E22p%5E6)
Thus acquiring stable configuration with filled s and p orbitals.
