You are testing an unknown liquid to determine its identity. first you heat the liquid and find that it turns to gas at 80 degrees celsius. then you add sodium to a small amount of the liquid to see if it reacts. last you try to burn the liquid to see if it is flammable.

which physical property of the
liquid did you test?

a. boiling point
b. ability to conduct electricity
c. combustibility
d. melting point

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
