Q. 3.71 - An Introduction to General, Organic, and Biological Chemistry

Question

Classify each of the following as an element, a compound, or a mixture; $\left(3.1\right)$

a. carbon in pencils

h. carbon monoxide (CO) in automobile exhaust

c. orange juice

Step-by-Step Solution

Answer

There is one sort of atom in an isotope. A compound is comprised of two or more unique atoms that are linked together. A mixture is made up of two or more separate components that are only bonded structurally, not biologically.

Step 1: Given information (a)

The most widespread mineral used to build crayon shafts is graphene. These leads are made out of an incoherent alloy of earthenware and graphene. Hematite is a brittle carbon that occurs naturally.

Step 2: Explanation (a)

 (a) carbon in pencils is a pure substance. It consists of only one type of material i.e., carbon. Hence, it is an element.  

Step 3: Given information (b)

Soot carbon monoxide (CO) is a synthetic component composed of two properties: soot and an oxidant. These ions covalently bond to form a network. Diesel exhaust monomers are always composed of  carboxyl groups and isotopes.

Step 4: Explanation (b)

(b) Carbon monoxide in automobile exhaust is a compound. Although the automobile exhaust is a mixture of different gases. carbon monoxide is a compound present in that mixture. 

Step 5: Given information (c)

Orange juice is a hybrid because it incorporates a range of flavours and metabolites that do not unite in a deliberate manner. It isn't a completely perfect substance. It's neither an isotope nor a synthesis alone.

Step 6: Explanation (c)

Orange juice consists of different organic compounds , water, etc.., Hence, orange juice is a mixture .
