Question 1 Prior to 1886, Aluminum was rarer and more expensive than gold! It was in 1886, that brother and sister Charles Martin Hall and Julia Brainerd Hall discovered the electrolytic process that separated Aluminum from Aluminum Oxide ore. Today, over 41 million tons are processed for use in everything from beer cans to aircraft skins. a) How many coulombs of electricity must pass through the cell to produce 40.0 g of Aluminum (26.981539 g/mol)Fm an Ala(Soy), cap solution "....

Although child mortality rates have dropped by more than 50% since 1990, in 2015 it was still the case that 16,000 children under five years old died each day. The mortality rates for children under five varied from 1.9 per 1000 in Lasembourg to 156.9 per 1000 in Angola. Although the data set includes 213 countries, the child mortality ratecs of available on the World Health Organization database. The data set is too large to show, so the table contains...
