Q:

What is a hydrated crystal?

A:

Quick Answer

A hydrated crystal is a crystal with water molecules bonded to its ions. Although it contains water, it is still a solid. It is created from a highly ionic substance that crystallizes from a water solution.

Full Answer

Although hydrated crystals are solids, the water molecules can be removed through the crystal lattice by heating. Heating occasionally causes hydrated crystals to shatter in the process of removing the water molecules. If the crystal remains intact, the heating process forms an anhydrous crystal, which means "without water." Hydrated crystals generally change color once they become anhydrous.

Hydrated copper sulfate is a common type of hydrated crystal and is blue in color.

    What is the rock that has an igneous texture characterized by two distinctly different crystal sizes?

    A:

    Porphyritic rock is a texture of igneous rock with two distinctly different crystal sizes due to two periods of cooling occurring at different rates. Larger crystals are called phenocrysts, while the smaller grains are known as groundmass or matrix.

    What are the six basic crystal shapes?

    A:

    There are seven basic crystal shapes: cubic (isometric), tetragonal, orthorhombic, hexagonal, trigonal, triclinic and monoclinic. A crystal's shape is determined by one of seven crystal lattice systems, which are used to describe the crystal's geometric symmetry.

    What is the difference between diamond and graphite?

    A:

    The primary difference between diamond and graphite is the way their carbon atoms are arranged to form their physical crystal structures. The arrangement of carbon atoms in diamonds makes them bond together strongly, while graphite atoms are held together with a weaker bond, creating a soft physical substance.

  • Q:

    What is the difference between rock and stone?

    A:

    According to National Geographic, the main difference between rocks and stones, or gemstones, are their rarity and crystal formation. Most gemstones have a crystal formation, which makes them rare and valuable after they are cut. Rocks usually do not have a crystal formation, which means they are not considered to be of value. Unlike rocks, gemstones are classified on their rarity and value into two categories: semiprecious and precious.
