How does the law of conservation of mass apply to this reaction: C2H4 + O2 → H2O + CO2?
Because all atoms are made from the same particles which are protons, neutrons, and electrons.
Hope this helped!!!
The correct answers are
-formation of a precipitate
-bubble formation
-color change
-temperature change
-odor formation
The only one that isn’t correct is change in state of matter. A change in a state of matter does not mean it’s a chemical change. For example, water boiling so it turns into gas is not a chemical change, and is a physical one. Also, water can freeze and turn into ice, which is also still a physical change. If something changes state of matter, it does not necessarily mean it’s a chemical change.
