I was on the phone to see if you wanted me a couple questions and I would be able answer questions on how
The conversions that will be used are:
1 mole of copper / 63.5 grams of copper
6.02 x 10²³ atoms of copper / 1 mole of copper
Multiplying the given mass by these conversions,
660 g * (1 mol Cu / 63.5 g Cu) * (6.02 x 10²³ Cu atoms / 1 mole Cu)
The sample contains 6.25 x 10²⁴ atoms of copper
Then as the electrons in the atoms fall back down, they emit electromagnetic radiation (light). The amount of light emitted at different wavelengths, called the emission spectrum, is shown for a discharge tube filled with hydrogen gas in Figure 12.6 below.
Answer:
A physical property is any property that is measurable, whose value describes a state of a physical system.
Explanation:
-color
-density
-volume
I'm pretty sure all 4 are subatomic particles but if i had to guess i'd be Photons
