How do you write chemical symbols of compound?
Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.
When and where was the element H2O discovered?
Water (H2O) has been known since ancient times, so it wasn't "discovered" in the traditional sense. However, the chemical composition of water was first identified in 1783 by the French chemist Antoine Lavoisier, who demonstrated that it is a compound made of hydrogen and oxygen. Lavoisier's work laid the foundation for modern chemistry, although the understanding of water as a compound developed over time through contributions from various scientists.
What chlorine gas is. Who used it first?
The gas chlorine is a halogen with the chemical symbol Cl; chlorine was discovered by Carl Wilhelm Scheele.
Who discovered electric current?
Electric current was discovered by Alessandro Volta in 1800 when he created the first chemical battery, the voltaic pile.
Who discovered what elements were combined to make up water?
The composition of water, made up of hydrogen and oxygen, was first discovered by the English scientist Henry Cavendish in 1781. He conducted experiments that identified water as a compound of these two elements.
When was acetaldehyde discovered?

What was the first compound of xenon?
It was xenon hexafluoroplatinate, Xe{PtF6]
First discovered compound formed by Xenon is?
The first discovered compound formed by xenon is xenon hexafluoroplatinate (XePtF6). It was reported in 1962 by Neil Bartlett who successfully synthesized this compound by reaction of xenon gas with platinum hexafluoride.
How was hexane discovered?
Hexane was discovered as a fraction of crude oil in the 19th century during the development of the petroleum industry. It was first isolated and identified as a distinct chemical compound in the early 20th century by chemists studying the properties of various hydrocarbons found in petroleum.
Can a compound be broken down into smaller with chemical changes only?
Next time, try wikipedia first before posting here. you'll save yourself time. this is from the very first line of the wikipedia article for "compound":A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions.
How do you build a compound from the chemical formula?
To build a compound from a chemical formula, first identify the elements present in the formula. Then, determine the ratio of each element in the compound. After that, use this information to arrange the atoms in the correct structure following the rules of chemical bonding.
What is first chemical element discovered?
The first chemical element to be discovered was gold. It has been known to humans since ancient times due to its distinctive physical properties and rarity.
Who was the first scientist who discovered chemical and physical processes?
Unknown; the knowledge of the chemical and physical processes are very old.
