Mixtures can be classified as <u>homogeneous </u>or <u>heterogeneous</u>.
Answer:
2.64 ×
J
Explanation:
I think you should mark it a physics question instead but anyway.

The Planck equation should be applied:
E = hv , while E is energy of proton; h is Planck constant; and v is frequency.
E = 6.6 ×
× 4 × ![10^{7}](https://tex.z-dn.net/?f=10%5E%7B7%7D)
= 6.6 × 4 × ![10^{-27}](https://tex.z-dn.net/?f=10%5E%7B-27%7D)
= 2.64 ×
J
A) The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion.
b) Gaseous particles tend to undergo diffusion because they have kinetic energy.

Barium Ba 137.327
Hydrogen H 1.00794
Oxygen O 15.9994
Hope this helps, good luck
I believe it’s physical property because there is no chemical reaction to an unlit match♀️
