Answer:
keep adding to on each term its quit simple
Each isotope has a unique rate of decay, making them suitable for determining the dates of ancient artifacts. The answer is "rate of decay of the isotope."
A) in pure water :
by using ICE table:
According to the reaction equation:
BaCrO4(s) → Ba^2+(aq) + CrO4^2-(aq)
initial 0 0
change +X +X
Equ X X
when Ksp = [Ba^2+][CrO4^2-]
by substitution:
2.1 x 10^-10 = X* X
∴X = √2.1 x 10*-10
∴X = 1.4 x 10^-5
∴ the solubility = X = 1.4 X 10^-5
B) In 1.6 x 10^-3 m Na2CrO4
by using ICE table:
According to the reaction equation:
BaCrO4(s) → Ba^2+(aq) + CrO4^2-(aq)
initial 0 0.0016
Change +X +X
Equ X X+0.0016
when Ksp = [Ba^2+][CrO4^2-]
by substitution:
2.1 x 10^-10 = X*(X+0.0016) by solving for X
∴ X = 1.3 x 10^-7
∴ solubility =X = 1.3 x 10^-7
Answer:
D) contains more OH– ions than H+ ions
Explanation:
Bases have high concentration of hydroxides (OH-) and acids have high concentration of (H+) ions
Answer:
Explanation:
The music of France reflects a diverse array of styles. In the field of classical music, France has produced several prominent romantic composers, while folk and popular music have seen the rise of the chanson and cabaret style. The earliest known sound recording device in the world, the phonautograph, was patented in France by Édouard-Léon Scott de Martinville in 1857. France is also the 5th largest market by value in the world, and its music industry has produced many internationally renowned artists, especially in the nouvelle chanson and electronic music.
