Good morning class, today, we're having a visitor that will teach us some of the use of the elements in periodic table
A Scientist!
Hello everyone I am Peter Armstrong, a scientist
And now I'll introduce some of of the use of elements that you see in periodic table
The combination of hydrogen (H) and chlorine (Cl) can make a hydrochloric acid or muriatic acid that use in production of batteries, photoflash, bulbs and fireworks.
another one, the combination of carbon (C), hydrogen (H), and oxygen (O) can make a vinegar that can use in food preparation .
Good bye and thank you Mr. Armstrong !
and that's all, thank you for your cooperation and I hope that you've learn a lot from me.
