Because you can't make a closed shape with <2 lines.
Yes - that is usually correct
A roman numeral in parentheses follows the name of the metal... apex
In 1810, Sir Humphry Davy discovered that Chlorine was an element, not a compound as was first thought. He named Chlorine after the Greek word χλωρος (chlōros), meaning green-yellow (the colour of Chlorine).
If both of the compounds named in the question are in solution in water, barium sulfate will precipitate. If both are solids when mixed, there will usually be no reaction.
They are termed organic compounds. Compounds containing only carbon and hydrogen are called hydrocarbons and they are a subset of organic compounds.
Cyclomethane and cycloethane: "cyclo" referes to a closed shape (triangle, square, pentagon, hexagon, etc.), for that you need at least three points (in this case carbon). Therefore it is impossible to make a "cyclo" structure with one dot/carbon (methane) or two dot/carbon (ethane) Avogadro's constant: It was the original value, and to honour the scientist who discovered it, the scientific comunity is keeping it that way. It's just the way things are: why does a dozen = 12 and not something like 10? Why is pi or e such a weird number? etc.
HCl, and you get water as another product.
They are usually named as chlorides.
Covalent compounds share electronsCovalent compounds are neutralB.The compounds share electrons.C.The compounds show no charge.D.The compounds are named with Greek prefixes.
yes
Proteins, carbohydrates, and many others.
Chemical compounds are not named in Roman numerals!
Cytosine pairs with guanine Adenine pairs with thymine (or with uracil in RNA)
Nonmetals(anion) are written second after the metal(cation).
