Question

which is made up of organic molecules?

copper electrical wires
plastic storage containers
table salt
antacid

Explanation:

Define organic molecules

Using the Organic Compounds knowledge point
Organic molecules are carbon-based compounds, typically containing carbon-hydrogen (C-H) bonds, often forming long chains or complex structures.

Analyze copper electrical wires

Copper wires are made of elemental copper (\(\text{Cu}\)), which is a metallic element and entirely inorganic.

Analyze plastic storage containers

Using the Synthetic Polymers knowledge point
Plastics are synthetic polymers made from petrochemicals, consisting of long chains of carbon and hydrogen atoms, making them organic.

Analyze table salt

Using the Inorganic Compounds knowledge point
Table salt is sodium chloride (\(\text{NaCl}\)), an ionic compound that does not contain carbon, classifying it as inorganic.

Analyze antacid

Antacids typically consist of inorganic bases, such as calcium carbonate (\(\text{CaCO}_3\)) or magnesium hydroxide (\(\text{Mg(OH)}_2\)), which do not contain organic carbon-hydrogen bonds.

Answer:

• copper electrical wires
• plastic storage containers (Correct answer)
• table salt
• antacid
