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 else can I help you with?
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
Number and type of element of the atom fe2o3?
Four: the answer to such questions is always obtainable by summing the subscripts in the formula (remembering that no explicit subscript means one atom per formula unit of the element symbol without a subscript) unless the formula includes parentheses; in that instance, the subscripts within the parentheses must be multiplied by the subscript after the right parenthesis before summing.
What Never change a subscript to balance an equation?
Subscripts in a chemical formula represent the number of each atom present in a compound. Changing a subscript without changing the corresponding coefficients in a balanced chemical equation would alter the chemical formula and lead to an unbalanced equation. To balance the equation, adjust the coefficients in front of the compounds rather than changing the subscripts.
What is this empirical formula - C5H8NO4?
C4h5n2o
How many atoms are in 3n2?
6. When a formula contains no parentheses and only one kind of atom, the total number of atoms equals the product of the subscript and the coefficient.

What property allows the grouping of numbers in parentheses to change without changing the answer?
That would be the associative property. The associative property applies to addition and multiplication, but not to subtraction or division.

What is 2(x-5) without parentheses?
2(x-5) without parentheses = -3
Why are parentheses used in formulas?
Parentheses in formulas are used to establish the order of operations. They help clarify which operations should be performed first and ensure that the formula is evaluated correctly. Without parentheses, the formula could produce a different result than intended.
How do you get the 2 in CO2 to get smaller?
The subscript "2" in CO2 represents the number of oxygen atoms in each molecule of carbon dioxide. The size of the subscript cannot be changed without altering the chemical formula and the fundamental structure of the compound.
Should a paraphrase be in a parentheses?
No, a paraphrase should not be in parentheses. When paraphrasing, you should reword the original text in your own words, without the use of parentheses.
What equals 15 in parentheses?
' 15 ' without parentheses does. Except in Accounting, where (15) means ' -15 '.

To balance the equation, adjust the coefficients in front of the compounds rather than changing the subscripts.
What do the numbers in a formula for a compound tell you?
Subscripts give you the number of molecules in that compound. (For example, H2O contains one molecule of Hydrogen.) Superscripts give you a charge.Read more: If_a_formula_for_compound_what_do_the_numbers_tell_you
