The scientist Joseph Priestley is often credited with discovering oxygen in 1774 through his experiments with heating mercuric oxide. However, the discovery of oxygen is also attributed to Carl Wilhelm Scheele and Antoine Lavoisier around the same time.
No, nitrous is not the same thing as nitrogen. Nitrous oxide, commonly known as laughing gas, is a compound made up of nitrogen and oxygen. Nitrogen is a chemical element that makes up about 78 of Earth's atmosphere and is a separate substance from nitrous oxide.
Yes: An oxide ion has a charge of -2. Two of them have a combined charge of -4, which is exactly neutralized by a manganese (IV) cation.
Oh, dude, Mercury is definitely a homogeneous mixture. It's all the same stuff throughout, like when you mix sugar in your coffee and it dissolves completely. So yeah, Mercury is like that cool kid who always blends in perfectly wherever it goes.
In 1772, Priestley made another important discovery. He had placed a shoot of a green plant into a container of water. He then covered the container and lit a candle in it until it completely burned out. Later, Priestley was able to both burn the candle again and keep mice alive in the air (did they have lab mice back then?). Priestley became the first person ever to observe the photosynthesis in plants - the fact that they take in carbon dioxide and release oxygen.
same thing as oxygen no subscripts needed
metal and metallic are the same thing arent they??
No, nitrous oxide and helium are not the same thing. Nitrous oxide, also known as laughing gas, is a dental sedative and anesthetic gas, while helium is a noble gas commonly used in balloons for buoyancy. They have different properties and uses.
Mercury is named after the ROMAN god Mercurius (Mercury).
Titanium Oxide or Zinc Oxide, the same thing that makes sunscreen white are both common white pigments
No, the planet Mercury is just called Mercury. The element Mercury (Hg) is a chemical element and has nothing to do with the naming of the planet Mercury.
Quicksilver is the same thing as the element Mercury and therefore has the same properties as this element.

When mercury(II) oxide (HgO) is heated, it decomposes into mercury and oxygen. The atoms present in the compound at the start of the reaction are mercury (Hg) and oxygen (O), and these same atoms will be present at the end of the reaction, just in different molecular forms.
No, nitrous is not the same thing as nitrogen. Nitrous oxide, commonly known as laughing gas, is a compound made up of nitrogen and oxygen. Nitrogen is a chemical element that makes up about 78 of Earth's atmosphere and is a separate substance from nitrous oxide.
No, nitrous oxide (laughing gas) and helium are not the same thing. Helium is an inert gas commonly used in party balloons and as a cooling agent in various applications, while nitrous oxide is a colorless gas often used as an anesthetic or in whipped cream dispensers.
Yes: An oxide ion has a charge of -2. Two of them have a combined charge of -4, which is exactly neutralized by a manganese (IV) cation.
