Dr Mae Jemison Dr Mae Jemison was the first black woman to go into space, blasting into orbit aboard the Space Shuttle Endeavour on 1 September She was Science Mission Specialist and carried out research on bone cells. "I knew ever since I was a little girl that I wanted to go into space."
Dr Bernard A Harris In 1993 Dr Bernard A Harris became the first African-American to walk in space. In February 1995 he was the Payload Commander on the first flight of a new joint Russian-American space programme. As the first African-American in space, Dr Harris said: "To be the first was great. But to me, it signifies that there would be many more behind me."

8. Covalent Compounds
form when two nonmetals and/or
a metalloid and a nonmetal bond

9. To name covalent compounds
Covalent compounds are composed of two or more nonmetals which share electrons. (Some metalloids are covalently bonded as well).

but = 4
pent = 5
hex = 6
hept = 7
oct = 8
non = 9 …
Organic compounds have one or more carbons, surrounded with hydrogens.
They may have double or triple bonds, and may include oxygen, or other atoms.
They are named by counting the “carbon backbone” and applying a prefix
“Functional Groups” provide the rest of the name.
