Which physical property can be measured? color density odor shape
The physical property that can be measured is the density. Color, odor and shape are properties that cannot be measured. They can be only observed through the naked eye and is subject to qualitative measurement.

b) I took the test
Explanation:
B. Kryptonite
C. Quartz
D. Pyrite
This reaction is best described as
(1) addition involving a saturated hydrocarbon
(2) addition involving an unsaturated hydrocarbon
(3) substitution involving a saturated hydrocarbon
(4) substitution involving an unsaturated hydrocarbon
This reaction is best described as substitution involving a saturated hydrocarbon. Therefore, the correct option is option C.
When one atom or group of atoms in a molecule is replaced by another atom or group of atoms, the chemical reaction is known as a substitution reaction. Usually, a reactant molecule and a reagent molecule, which supplies the replacing atom or group, engage in this reaction. Nucleophilic substitution and electrophilic substitution are the two primary categories of substitution processes. A nucleophile (a substance rich in electrons) can replace another atom or group in a molecule in nucleophilic substitution processes. A nucleophile combines with an electrophile (an electron-deficient species) in organic chemistry regularly to produce this kind of reaction, which results in the formation of a new molecule.
