Answer:
The atomic theory has changed over time as new technologies have become available. Scientific knowledge builds on past research and experimentation. 400 B.C. Democritus, a philosopher in ancient Greece, began the search for a description of matter.
Explanation:
AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
Ksp=[A²⁺][B⁻]²
a=1.10 g/L
M=169 g/mol
c=a/M
[A²⁺]=c=a/M
[B⁻]=2c=2a/M
Ksp=(a/M)(2a/M)²=4(a/M)³
Ksp=4*(1.10/169)³=1.103×10⁻⁶
Answer:
Al is aluminum. Bromine gas is Br2
Explanation:
Al + Br2 = AlBr3
