What evidence led you to formulate the composition of the solid residue after heating the marble chip?
The evidence is by chemical analysis.
What is the evidence of chemical changes in a fire cracker that explodes?
yes, a chemical change.. Often silver fuminate AgCNO is used as the "explosive" The products of explosion include CO and N2
Are changes in properties always evidence of a chemical change and why?
No. Boiling water is a physical not a chemical change, and yet clearly steam has very different properties than liquid water does. A chemical change is one which will change the composition or identity of the material. So not only will its properties change, but it's chemical composition will also be changed
What would most likely be found in a supporting sentence?
Evidence and statistics are most likely found in a supporting sentence.
Which is not evidence that Earth is a sphere?
the core's composition of nickel and iron

What is the only sure evidence for a chemical reaction?
The only way to be sure a chemical reaction or change has occurred is to test the composition of a sample before and after a change.
If you were required whether a particular metal had reacted with a specific reagent what sensory evidence could be used to argue that a chemical transformation of the substance had occurred?

Is it legal to charge someone with a felony if there is no evidence supporting it?

What is chemical evidence?
Chemical Changes involve a change in chemical composition in the substances which are being investigated so you cannot easily get back your original substances as something new has been formed. Some examples of chemical changes are a gas is produced, the temperature changes, a substance disappears, a solid is formed, a color change occurs, and a new odor is produced.
Are we ever obligated to trust our emotions without any clear supporting evidence?
We are never obligated to trust our emotions, even withclear supporting evidence. However, it seems we often do trust our emotions even when that is contrary to clear supporting evidence that we should not.
What changes are evidence for a chemical change?
Remember that a chemical change is anything that alters the identity or composition of a substance. So something such as color change, a solid being formed, a gas being produced or temperature changing would constitute a chemical change.
