They are all ions.
Yes. The atoms of iron contain different number of protons, neutrons, and electrons that the atoms of tin do.
Yes. Their atomic mass is different, among other things.
0,0178 moles of tin is equal to 0,107.10e23 atoms.
The number of atoms is 18,066.10e23.
The mass of tin is slightly more than the relative atomic mass of tin (118.71). There will be 6.037*10^23 atoms.
41.7 grams tin (1 mole Sn/118.7 grams)(6.022 X 10^23/1 mole tin )(1 mole tin atoms/6.022 X 10^23) = 0.351 moles of tin atoms in pure tin cup ------------------------------------------------------
there are .476 moles in 250 grams of tin
In the gas phase 3, 1 atom of Tin and 2 atoms of Chlorine.
Because a tin can is a solid the atoms are more densly packed therfore the sound wave travels faster through the atoms in a tin can as opposed to air where the atoms are spaced further Apart.
yes tin is a neutral atom, all atoms are by definition neutral.
There are 57.6 grams of tin in that sample.
No, because those elements have different atomic weights, meaning that the nuclei have different numbers of protons and neutrons (Tin has more than Iron). However, if those protons and neutrons were examined individually then, according to current theory, they would all appear alike.
Tin is pure, because it is found on the periodic table therefore is an element made up of only tin atoms
Tin has 50 protons and lead has 82 protons.
This mass is 28,8.10e-20 g.
2.95 X 1024 atoms tin (1 mole Sn/6.022 X 1023)(118.7 grams/1 mole Sn) = 581 grams of tin =============
250 (g Sn) / 118.710 (g/mol Sn) = 2.106 mol Sn = = 2.106 * 6.02*1023 (atoms / mol) = 1.27*1024 atoms of Sn (Tin)
1 mole of anything is 6.022 x 1023 atoms or molecules of that substance. Thus, 2500 atoms of a substance is about 4.151 x 10-21 moles of that substance.
The tin will dissolve u can try by put a small piece tin with soda and then check on it over the time period
It is a physical change because you are changing the physical shape of the piece of tin foil. You are tearing it, and now it becomes two pieces.
