A compound has to be chemically bonded, however, air is not chemically bonded.
This can be proven by freezing air. By freezing air, it yields different liquids at different temperature. Liquid nitrogen has a different boiling point than liquid oxygen.
If air was a compound, they would all have a single boiling point and a single freezing point.
Hope this helps :)

Electrical energy accelerates the electrons in the neon gas. The gas ionizes and becomes plasma, containing both positive and negative ions.</span>
Answer:
Isotopes of bromine have same chemical properties because they have same number of electrons.
Isotopes have only different number of mass that does not affect it's chemical properties too much.
Answer:
Explanation:
Given data:
Mass of water used = 4.05 g
Mass of each product produced = ?
Solution:
Chemical equation:
2H₂O → 2H₂ + O₂
Number of moles of water:
Number of moles = mass/ molar mass
Number of moles = 4.05 g/ 18 g/mol
Number of moles = 0.225 mol
Now we will compare the moles of water with hydrogen and oxygen.
H₂O : H₂
2 : 2
0.225 : 0.225
H₂O : O₂
2 : 1
0.225 : 1/2×0.225 = 0.113 mol
Mass of hydrogen:
Mass = number of moles × molar mass
Mass = 0.225 × 2 g/mol
Mass = 0.45 g
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 0.113 mol × 32 g/mol
Mass = 3.616 g
In order to do this you must add up all of the molar masses of each compound and then judge accordingly.
