When battery discharge / delivering current the lead at the anode is oxidized
that is ;
pb---->pb+ 2e-
since the lead ions are in presence of aquous sulfate in insoluble lead sulfate precipitate onto the electrode
the overall reaction at the anode is therefore
Pb + SO4^2- ---> PbSO4 + 2e-
Answer:
Alkylenes: any of the series of unsaturated hydrocarbons containing a triple bond, including acetylene.
alkanes: Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups. Alkanes have the general formula CnH2n+2 and can be subdivided into the following three groups: the linear straight-chain alkanes, branched alkanes, and cycloalkanes.
Explanation:
WHAT THE HECK!?!?!?! AM I SUPPOSE TO KNOW WHATEVER LANGUAGE THAT IS?!?!
Swallow hole is also known as a sinkhole refers to a hole or depression in the ground resulted due to certain kind of collapse of the surface layer. The majority of them are the result of karst procedures, like the suffosion processes or the chemical dissolution of the carbonate rocks.
The sinkholes differ in size from 1 to 600 meters, both in depth and diameter, and differ in form from soil-lined bowls to bedrock-edged chasms. The sinkhole may get produced suddenly or slowly, and are observed all through the globe.
