1. the line would run up the paper. should have drawn with pencil.
2. the samples would dissolve into solvent and not run up the paper.
<span>There are 2.74603 * 10^25 hydrogen atoms. Ammonium sulfide is represented by (NH4)2S. This means that there are 8 hydrogen atoms total. There are also 8 mol of H in ammonium sulfide. We also need to use avogadro’s number of 6.022 * 10^23.
Hydrogen Atoms = 5.7mol * (8mol / 1mol) * 6.022 * 10^23 per mol
Hydrogen atoms = 2.74603 * 10^25 hydrogen atoms.</span>
Answer:
6. Color Change.
Production of an odor.
Change of Temperature.
Explanation:
That is the only one I know :)
A good example is cigarretes they try to scare you into not smoking by telling you all of the downsides of smoking like lung cancer and i guess that would be fear appeal
Answer:
Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1
Explanation:
because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.
