Priestly had first found this new element when he observed that mercuric oxide, on heating. Yielded a gas that caused a flame to burn faster.
He later found that it could support respiration and therefore he named it air. It wasn't until a French chemist Antoine Laurent Lavoisier found it to be an elemental gas.

As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
