Hi There! :)
<span>Which elements in the periodic table are metalloids or have semimetallic properties?
</span><span>Boron, Silicon, Germanium, Arsenic, Antimony, and Polonium are all metalloids. Some people consider Astatine a metalloid</span>
δg° for the reaction having e° cell = 2.04v. is 393.658kJ.
The lead (Pb) in the lead storage battery act as an anode
<h3>What is Voltaic Cell?</h3>
A voltaic cell or galvanic cell is an electrochemical cell that uses chemical reactions to produce electrical energy.
<h3>Parts of voltaic cell</h3>
Anode where oxidation occurs Cathode where reduction occurs.
Therefore, Pb acts as anode and PbO2 act as a cathode.
Given,
E° cell = 2.04v
Faraday constant= 96485 C/mol
Moles of electron transferred n= 2
∆G = -nFE°
= -2 × 96485 × 2.04
= 393.658kJ
Thus we concluded that the δg° for the reaction having e° cell = 2.04v. is 393.658kJ.

Methane also is the chief constituent of natural gas, which contains from 50 to 90 percent methane (depending on the source), and occurs as a component of firedamp (flammable gas) along coal seams.
The answer is B. uniform in composition.
