In a lead-acid storage battery, how is the cell potential affected when the concentration of the acid in the battery is increased? a. the cell potential decreases. b. the cell potential does not change. c. the cell potential becomes zero. d. the cell potential increases.

Cell potential becomes zero when the concentration of the acid increases and it result in battery stratification.  

Option: c

Explanation:

This happens because sulfuric acid in ‘electrolyte mixture’ divides from the water and begins to concentrate at the bottom of the battery.  So increase concentration of acid increases the formation of lead sulfate i.e sulfation took place and gets discharged.  Hence immediately needed to be charged to avoid hard crystals which lead sulfate start forming and then it cannot be reconverted.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
