The net cell reaction for the iron-silver voltaic cell would be:
<span>3Ag+ + Fe --------> 3Ag + Fe3+
</span>
wherein it comes from the reaction of the cathode and the anode:
<span>Ag+ + e- -------> Ag, for the cathode and;
</span>
<span>Fe -------> Fe3+ + 3e-, for the anode
</span>
When both equations would be multiplied, the it would now yield the balanced net reaction as stated above.
Hey there! The answer to your first question is SILICON, Nickle has 28 protons, silicon has 14, 14+14=28. Its the only element thats adds up. I dont know about the 2nd one myself.
Answer: The answer would be, "Has mass of 1 amu".
Explanation:
Answer:
The answer to your question is C₂H₆O
Explanation:
Data
Molecular formula = C₆H₁₈O₃
Empirical formula = ?
Empirical formula is defined as the simplest ratio of the elements that form part of a molecule.
Process
To find the empirical formula find the greatest common factor of the subscripts.
6 18 3 2
3 9 3 3
1 3 1 3
1
The GCF is 3, so factor 3 of the molecular formula
3 ( C₂H₆O)
The result is the empirical formula C₂H₆O
a.200.59 amu of mercury contains = 6.02 * 1023 molecules
Mass for 3.0 * 1023 molecules = (3.0 * 1023 * 200.59) /6.02 * 1023
= 100.29 amu
Thus, mass for 3.0 * 1023 molecules is 100.29 amu
b.As, 200.59 g mercury contains = 6.02 * 1023 atoms
1 g mercury contains = (6.02 * 1023 /200) atoms
= 3.01 * 1021 atoms
Thus, 1 ng mercury contains = (3.01 * 1021) / 109
= 3.01 * 1012 atoms
Thus, 3.0 * 1012 atoms present in 1 ng mercury
