Answer:
IUPAC, which stands for International Union of Pure and Applied Chemistry, has a rules that guides the naming of aliphatic compounds these are explained below.
Explanation:
The International Union of Pure and Applied Chemistry ( IUPAC) has put forward a system of nomenclature which relates the me of the compound to its molecular structure. In this system, every name consists of:
--> A ROOT: This is generally the aliphatic hydrocarbon.
--> the SUFFIX: This is added to the root to indicate the presence of the principal substituent. For example the names of alkanes ends with '-ane'.
--> as many PREFIXES as necessary.
The systematic name of a compound is formed from the root hydrocarbon by adding a suffix and prefixes to denote the substitution of the hydrogen atoms.
Basic rules in to name aliphatic compounds include:
--> Take the longest continuous carbon chain as the root hydrocarbon and name it according to the number of carbon atoms it contains, adding the appropriate suffix to indicate the principal substituent group.
--> Number the carbon atoms in the root hydrocarbon from the end which will give the lowest number to the suffix, and then the prefixes.
--> Indicate the other substituents by prefixes preceded by numbers to show their positions on the carbon chain.
Answer:
they change the state of matter
Explanation:
Physical properties can be observed or measured without changing the composition of matter
Chemical properties are only observed during a chemical reaction and thus changing the substance's chemical composition

Answer:
2
Explanation:
The sample has halved twice.
1/2 of 1/2 is 1/4, and 1/2 of 1 is 1/2.
