In a formula without parentheses a subscript applies?
e.g. H2SO4 #1 the number should be in subscript. #2 ; The No. '2' indicates that there are 2 x hudrogen . The No. '4' indicates that there are 4 x oxygen. Since sulphur(S) has no subscript no. the the letter inidcates that there is only '1' x sulphur. A full script nO. to the left of the formula indicates that there are two molecules needed to complete the reaction equation. e.g. 2H2SO4 = H2SO4 + H2SO4
What is the name of the indicated atom in acetic acid?
Well, you didn't indicate the atom so I'll do what I can. The formula for acetic acid is CH3COOH. If the indicated letter in the formula is C, the atom is carbon. If the indicated letter in the formula is H, the atom is hydrogen. If the indicated letter in the formula is O, the atom is hydrogen.
What is the chemical symbol for ethyl alcohol?
CH3CH2OH Note the use of the capital letters. The use of lower case single letter elements is incorrect. # It is NOT Ch3ch2oh'. In chemistry , single letter elements are always shown as a CAPITAL letter. e.g. H , O, C. Two letter elements are always written as ; first letter is a CAPITAL letter , and the second letter is always small/lower case. e.g. Fe, Na, Cl, When single letter elements are shown in a chemical formula they are still written as capital letters. Numbers after a letter, indicating the number of atoms of the prefixed element, are always 'SUBSCRIPT'. Regret to say I cannot indicate it here. Numbers written the the left of a molecule, indicating the molar ratio are always full script. e.g. 2H2O . The left hand number (2) is written full script, the '2' between 'H & 'O' should be written subscript. Similarly the '2' in CO2 ( Carbon Dioxide).
Does the letter H represent the formula for a chemical compound?
the letter H represents the element Hydrogen
Is MgO a ionic compound?
No. MgO is a compound called magnesium oxide. It is composed of two elements: magnesium and oxygen.Hint: if the chemical formula contains more than one capital latter than the substance is not an element.
what number represents the subscript in the formula shown?
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
What small letter subscripts do we use to indicate whether a substance is a solid?
The indication for a solid is (s) as in BaSO4(s); the subscript is not usual.
Is N the symbol for the element nitrogen?
Yes. More exactly, the letter "N" is the symbol for a single atom of nitrogen in a chemical formula. A subscript number following the symbol indicates the number of atoms present in the particular part of a specific molecular formula, but if that number is 1, no subscript is used.
What is a letter or number written beneath a line of print called?
A subscript is below the line, as in 52 or 5x; a superscript is above the line: 52.
In a formula without parentheses a subscript applies?

A full script nO. to the left of the formula indicates that there are two molecules needed to complete the reaction equation. e.g. 2H2SO4 = H2SO4 + H2SO4
How do you write a formula with physical state?
Put a subscript ed letter or letters in parentheses next to the chemical substance. (s) is solid (H2O(s) is ice). (l) is liquid (H2O(l) is liquid water). (g) is gas (H2O(g) is water vapor). (aq) means something is dissolved in water (NaCl(aq)).
What has the author Michael W Swagel written?
Michael W. Swagel has written: 'The determination of the g[subscript J]([superscript 3]P[subscript 1]) value and g[subscript J]([superscript 1]P[subscript 1]) value of barium and the ratio A([superscript 1]P[subscript 1])/[[Greek letter mu subscript O]g[subscript J]([superscript 1]P[subscript 1]) ] of mercury-199' -- subject(s): Barium, Mercury, Spectra, Spectrum analysis
A number that is lower and smaller than the letter symbols in a chemical formula that shows how how atoms of a substance are in a molecule is called?
coefficent
What does each letter in the formula stand for?
The elemental quantities contained in a substance. Go to the periodic table of elements for the meaning of the "letters".
True or false- a subscript is a small number written above a letter or number?
false
