My answer will be C. Law of Original lateral continuity. :)
True
Explanation:
The physical properties and the chemical reactivity of halogens are best investigated in several different compounds. Compounds of a substance gives us good knowledge about how they behave and exists in nature.
- Halogens are very reactive group of elements.
- Due to their high electronegativity, they are the most reactive on the periodic table.
- They tend to find one electron to complete their octet by all means.
- They favor reactions where they have easy access to electrons.
- When atoms combines, they have different chemical properties.
- When the molecules combine to form intermolecular bonds, it tells on their physical properties.
- The compounds of halogens is a very good way to investigate their chemical reactivity and physical properties.

Answer:
<u><em>No</em></u>, changes in matter are <em><u>physical changes</u></em>.
Explanation:
No. on the left side you will notice there is one Ca, and 2 oxygen. therefore on the right side there must be 1 Ca, and 2 oxygen. The correct answer would be Ca + O2 -> CaO2
I need more information but um Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water
