When heated zinc carbonate decomposed to form zinc oxide and carbon dioxide gas how do you knke decomposition is complete

This reaction is characteristic to metal carbonates, which decompose when heated to form the oxide of the metal and carbon dioxide gas.

Explanation:

Just did it...

If the temperature is sufficiently above the decomposition temperature, the mass of the mass will reach a steady level.  When this occurs, the decomposition is complete.  

Explanation:

If you have money and a mass spectrometer, you might consider monitoring the gas space above the zinc carbonate sample for CO2.  Once the sample stops emitting CO2, above the decomposition temperature, you may conclude the reaction has gone to completion.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
