Reacting with air is a chemical property because here two substances are reacting and changing their atoms and appearance, which can not be unchanged.
Chemical properties are those property properties of a substance that does not depend on the quantity of that substance.
For example, a magnet with a small amount of magnet has the same magnetic property and a large amount of magnet has the same magnetic property. The magnetic property of the magnet does not change with the amount of substance.
Air contains many gases, and substances when exposed to air, react with it and change their appearance and chemical appearance, this is a chemical change.
Thus, because two substances are here reacting and changing their atoms and appearance, which cannot be unmodified, reacting with air is a chemical attribute.

High stability over long time and source need not be replaced
High penetration and high ionization
A good source of beta radiation and has a half-life of 432 years
Answer:
Ionization smoke detectors use americium as a source of alpha particles. Alpha particles from the americium source ionize air molecules. This makes some particles positively charged and some negatively charged. ... Because of this shielding, the smoke detector poses no radiation health risk when they are properly handled.
Explanation:
Hope this helped! :D
The correct answer is (1) Chemical
Explanation:
A compound is the result of two or more chemical elements that bond to form new substances; for example, water is a compound because this contains two hydrogen atoms bonded to one oxygen atom. Moreover, compounds are the result of a chemical change that occurs as two or more substances interact in a chemical reaction, and this leads to the formation of bonds between the substances or the formation of compounds.
On the other hand, a physical change involves only a change in the state of the matter and a nuclear change leads to a change in the atom rather. Thus, the type of change that must occur to form a compound is a chemical change.
Answer:
The answer is
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = 5 mL
The density of the substance is
We have the final answer as
Hope this helps you
It's mass and volume.
Answer:
it is volume and mass
