In 1987, the 1st National Chemistry Day was declared by the American Chemical Society to promote the public’s understanding and appreciation of the role that chemistry plays in our everyday lives. To celebrate the event, a group of local area teachers, under the sponsorship of the MSU Local Section, organized a hands-on activities and chemical demonstration program on Saturday, Nov.
Venus is made up of a central iron core and a rocky mantle, similar to the composition of Earth. Its atmosphere is mainly made up of carbon dioxide (96%) and nitrogen (3%), with small amounts of other gases.
