Percent Composition by Mass. Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.
The best answer. :)
Answer:
See explaination
Explanation:
Since X is more reactive than Y
=> X is oxidized to X2+ and Y2+ is reduced to Y
Overall cell reaction is:
X(s) + Y2+(aq) => X2+(aq) + Y(s)

Yes the volume would be a big fat 0.0000
Answer:
Mountains or Islands
Explanation:
They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and into the mantle to melt
I believe the correct answer would be E. When aqueous solutions of NiBr 2 and AgNO3 are mixed, a precipitate forms. As these two solutions are being mixed a reaction would happen resulting to two new compounds which are nickel nitrate and silver bromide. The reaction would be:
NiBr2 + AgNO3 = NiNO3 + AgBr2
The precipitate that would be formed would be the silver bromide since most of the silver compound are not or has low solubility in water while most of the nitrate compounds are very soluble in water. Most likely, it would be the silver bromide that is the precipitate.
