A common car battery consists of six identical cells, each of which carries out the reaction: Pb PbO2 2HSO4- 2H --> 2PbSO4 2H2O * Suppose that in starting a car on a cold morning a current of 125 amperes is drawn for 21.0 seconds from a cell of the type described above. How many grams of Pb would be consumed

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
