What properties differentiate an ionically bonded compound from a covalently bonded compound

ionically bonded compound transfer its electrons while covalently bonded compound share their electrons. ionically bonded compounds are charged while covalently bonded compound are neutral

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

i would say b
