answer : i don’t knowww :)
Right spelling:
Answer: I don’t know. :)
1 mol of Xe has a mass of 131 grams
x mol of Xe has a mass of 12 grams.
1/x = 131/12 Set up proportion from the information above. Cross multiply
131x = 12 Divide by 13`
x = 12/131
x = 0.0916 mol <<<< ====
Just for fun
I don't know if a calculator would even tell me the number of miles in 12 grams of Xe
The diameter is 216 * 10^-12 meters. Maybe.
1 mol of anything is 6.02 * 10^23
0.0912 mols contain x atoms
1/0.0912 = 6.02 * 10^23 / x
x = 0.0912 * 6.02 * 10^23
x = 5.49 * 10 ^ 22 This thing is going to stretch out quite a ways.
1 atom = 312 * 10^- 12 meters.
5.049 * 10^22 = x meters.
x = 312 * 10^-12 * 5.49 * 10^22
x = 1.7 * 10 ^10 km = 1.07 * 10 ^10 miles We're talking about beyond Pluto.
I'm sorry I should delete this. If you want to you can. Take my answer for the number of mols. It's likely correct.
Answer: Any Alkali metal
Explanation:
T he cool thing about the periodic table is the way it is organized. You can find chemical with similar properties is just looking in the column they are in in to determine the answer. Since Na is in the first column, any of these answer can work:
Li, K, Rb, Cs, and Fr
The answer we be C. which is karst topography.
He is making a conclusion from a single observation.
Silver isn’t the only metal that is shiny and has no colour.
For example, lithium, sodium, magnesium, and aluminium all have about the same colour as silver.
