Question

CAN SOMEONE PLEASE HELP ME!!!! I CAN'T GET ANY HELP IN THE SCIENCE SECTION!!!!!

Which of these experiments tests a chemical property of an object?

heating the object to determine its melting point

shining a bright light on the object and testing for decomposition

placing the object in water to see if it dissolves

trying to lift the object with a magnet

Answer 1

A chemical property would have to be something that changes and produces new substances. That is one of the main aspects of chemical changes/properties.

Heating an object to determine it's melting point is a physical property.

Shining a bright lighr and testing for decomposition however may be classifieds as a chemical properties because in the process of decomposition, organic substances are being broken. In physical properties, substances are not being broken.

Answer 2

Answer: shining a bright light on the object and testing for decomposition

Decomposition is the separation of a molecule into its elements or simpler compounds.

And a chemical property is the ability of a substance to combine or to become one or more substances.

Then, testing the ability of an object for decomposition is testing a chemical property.
