Question

Long answer type questions.
Represent the following using chemical symbol/formulae​

Answer 1

Answer:

ok

Explanation:

In order to illustrate chemical reactions and the elements and compounds involved in them, chemists use symbols and formulas. A chemical symbol is a one-or two-letter designation of an element. Some examples of chemical symbols are “O” for oxygen, “Zn” for zinc, and “Fe” for iron. The first letter of a symbol is always capitalized. If the symbol contains two letters, the second letter is lower case. The majority of elements have symbols that are based on their English names. However, some of the elements that have been known since ancient times have maintained symbols that are based on their Latin names, as shown in Table below .

Symbols and Latin Names for Elements

Chemical Symbol Name Latin Name

Na sodium natrium

K potassium kalium

Fe iron ferrum

Cu copper cuprum

Ag silver argentum

Sn tin stannum

Sb antimony stibium

Au gold aurum

Pb lead plumbum

Compounds are combinations of two or more elements. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. Water is composed of hydrogen and oxygen in a two to one ratio. The chemical formula for water is H 2 O. Sulfuric acid is one of the most widely produced chemicals in the Unites States and is composed of the elements hydrogen, sulfur, and oxygen. The chemical formula for sulfuric acid is H 2 SO 4 .
