Why to some copper compounds emit green light when they are heated?

When copper bonds with oxygen, it turns green. The copper is bonding with oxygen in the fire because there must be oxygen nearby because a fire needs heat, fuel, and oxygen.

How can a green penny turn green?
Pennies are made, or at least coated, with Copper and that copper can oxidize and turn green. Newer pennies have an alloy metal that is supposed to reduce this chemical action.
Why does when an unknown sample of a metal is placed in a flame a bright green light is released?
A green flame is due probable to copper.
Are all the compounds of copper plus 2 blue?
Not necessarily. They might be blue, green, or essentially white depending on how many waters of hydration are associated with the copper (II) ion. It's very easy to see this if you just take some copper (II) sulfate pentahydrate (blue vitriol) in a test tube and heat it; as the waters of hydration are driven off, the crystals turn white (some people call it a very light green; it looks white to me). When the crystals are allowed to cool they will absorb water from the air and eventually turn blue again. Aqueous solutions of copper (II) compounds are blue, as far as I know; at least I can't think of any counterexamples.
What is the importance of green plants as food producers?
The green plants perform photosynthesis and thus produce organic compounds like glucose from inorganic compounds like H2O and CO2 in their chloroplasts in the presence of light. All other food products are derivatives of photosynthetic products.
What colored chemical compounds absorbs light?
Many chemical substances absorb light.

If a light green powder is heated in a test tube A gas is given off while the solid becomes black In which classification of matter does the green powder belong?
The green powder is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
What is the Statue of Liberty original color?
Copper (brownish)
What are colored chemical compounds that absorb light in plants?
the colored compounds in them are chloroplast and chlorophyll that are colored green and absorb light for the process of photosynthesis....
Why does copper turn black when it meets oxygen?
Foolish Fools!, it does infact turn Green! because the oxygen bonds with the copper to form copper oxide, wich is green, it reflects different fractions of light to the copper
When a strontium compound is heated in a flame red light is produced When a barium compound is heated in a flame yellow-green light is produced Explain why these colors are emitted?
Yes

Why does fire turn green while burning copper?
Green fire is usually a result of the burning of copper sulfate. This occurs because when copper is heated, the electrons start to move very rapidly. This rapid movement causes the electon to move through different levels of energy. These different levels of energy cause different colors also known as the light spectrum. You can also cause fire to change colors by burning other chemicals such as lithium chloride (blue) and Calcium Chloride (intense orange).
Is a copper chloride solution blue?
Yes. The dihydrate is a light blue-green. Solutions are a pale blue-green in color.
