Q. What is naming covalent compounds?
In naming covalent compounds, each element in a covalent compounds needs a prefix to denote the number of atoms of that element. These prefixes are Greek (mon-, di-, tri-, etc) and the last element in the formula also gets the suffix “-ide.”
Q. Do you have to balance molecular compounds?
You can write the formula for a covalent compound from its name by writing the symbols for the first and second elements and translating the prefixes into subscripts. You aren’t balancing charges of covalent compounds; if the compound does not contain a metal, don’t try to balance this!
Q. How do you know if something is a molecule?
When an atom bonds with other atoms, either the same type (O2) or a different type (H2O), it’s called a molecule. Molecules are tiny so you can’t see them with the naked eye. However, scientists can break them down to their atomic parts. For example, water is made of two hydrogen atoms and one oxygen atom (H2O).
Q. Is O2 a molecule or compound?
The oxygen molecule O2 is considered a molecule but not a compound. This is because O2 is made of two atoms…
Q. Why oxygen is usually found as a molecule?
Oxygen is found naturally as a molecule. Two oxygen atoms strongly bind together with a covalent double bond to form dioxygen or O2. Oxygen is normally found as a molecule. It is called dioxygen.
Q. Is 02 a mixture?
A mixture contains more than one compound. O2 is just elemental oxygen. It’s a pure substance, but not necessarily because it only contains oxygen atoms, it’s because there’s only oxygen molecules present.
Q. Is caffeine a homogeneous mixture?
All the particles are the same. Different types of particles are mixed together….
| Material | Pure Substance or Mixture | Element, Compound, Homogeneous, Heterogeneous |
|---|---|---|
| Caffeine | PURE SUBSTANCE | COMPOUND |
