A macromolecule is a molecule with lots and lots of atoms. (i.e. protein, nucleic acid...)
A network solid is <span>is a chemical compound where the atoms are "bonded by covalent bonds in a continuous </span>network<span> extending throughout the material."
A single grain of sand consists of, on average, </span><span>~50,000,000,000,000,000,000 atoms.
That's A LOT.
However, these atoms do bond in network covalent bonds.
But that means it's a covalent network solid.
The short answer is that sand is both a </span><span>macromolecular substance as well as a covalent network solid, so I would go with it's macromolecular but you can interpret that the way you want.</span>
Answer:
A point is a 0-D object, infinitely small.
Explanation:
Carbon Dioxide
A positive test will result in the lime water turning milky. Lime water turns milky as the Calcium hydroxide (chemical name for limewater) reacts with carbon dioxide to form Calcium Carbonate which is insoluble in water and thus forms a milky white precipitate.
