We are given with a compound, Zinc (Zn) having a 1.7 x 10
^23 atoms. We are tasked to solve for it's corresponding mass in g. We need to
find first the molecular weight of Zinc, that is
Zn= 65.38 g/mol
Not that 1 mol=6.022x10^{23} atoms, hence,
1.7 x 10 ^23 atoms x 1 mol/6.022x10^{23} atoms x65.38
g/ 1mol
=18.456 g of Zn
Therefore, the mass of Zinc 18.456 g
Answer:
The most consistent mechanism is SN1.
Explanation:
The solvolysis of tert-butyl iodide in methanol will arise by the SN1 mechanism.
The reason for that is due the geometric structure of tert-butyl. The tertiary structure allows the formation of a stable carbocation, after the loss of the iodide ion. The carbocation will then be attacked by methanol molecules forming an eter.
<span>The Geiger counter contains a metal tube containing a wire (electrode) and gas. When nuclear radiation (X-ray or Gamma) enters the tube it ionizes the gas (strips electrons from gas atoms) allowing the gas to conduct electricity when the metal tube and electrode are maintained at a voltage differential. A circuit counts the frequency of ionizations. Alpha particles (helium nuclei) can be stopped by a sheet of paper and Beta particles (electrons) are often not energetic enough to penetrate metal.
