Hard question thx for the points
The atomic symbol that could represent an isotope that undergoes radioactive decay to produce Pb-206 would be 238/92 U.

The atomic mass of Ag is 107.87. The atomic mass of Cl is 35.45. The molecular mass of AgCl is therefore 143.32. 0.025 mols of AgCl were produced. This required .0125 mols of the original metal chloride since it has 2 chlorine atoms per molecule and AgCl only has one per molecule.
The molecular mass of mCl2 must be 127.2 in order for 1.59g of mCl2 to be .0125 mols. The molecular mass of m can be calculated by subtracting the molecular mass of 2 chlorine atoms
127.2-35.45-35.45=56.30</span>
Answer: Ag, Zn, Pd. (Ag is has the highest conductivity and Pd has the lowest conductivity).
Explanation:
The correct answer is not among the options given.
You must look up the electrical conductivity of these metals in a table of metal properties.
The values that you can find are:
- Ag: 62.1 × 10⁶ Siemmens / m
- Zn: 16.6 × 10⁶ Siemmens / m
- Pd: 9.5 × 10⁶ Siemmens / m
So in order of decreasing conductivity the list is Ag > Zn > Pd.
look at the chemical tables. but i believe it is A
