<span>the electrons change their energy states and photons in visible spectrum (and infrared spectrum) are emitted.More the losses, more would be the light, but at the same time, more would be the heat generated.So
this necessitates that the metal used should have high resistivity (and
hence high losses), good thermmal conductivity and high melting point.
hope it helps

The answer is the el second one since it is a physical change
Answer:
5.97 mol
Explanation:
To find the number of moles when given the mass of a substance, we divide the mass of the sample by its molar mass.
so, we get,
nN203 = 454 g / 76.01 g /mol
= 5.97 mol
Answer:
A
Explanation:
The answer A is the best answer because it contains the most general characteristic of a chemical change.
