The correct answer should be A
Answer:
C Metals are ductile, meaning they can be pulled into wires.
<span>a. 0.325 g / 63.55 g/mol = 5.11 X 10^-3 moles Cu. SHould form 5.11 X 10^-3 mol Cu2+
b. Should form 5.11 X 10^-3 mol Cu(OH)2
c. 1 g Zn / 65.4 g/mol = 0.0153 mol Zn
Excess Zn = 0.0153 - 0.0051 = 0.0102 moles excess zinc
d. 5.11 X 10^-3 mol Mg X 24.3 g/mol = 0.124 grams Mg</span>
Sn=2
C and O=6
Im pretty confident yet I forgot a bit.
D= mass/volume so it's 100/68 which equals 1.47cm3
