How are chemical formulas written do they use superscripts or subscripts?

Chemical formulas are written with the chemical symbol of each element followed by a subscript. If no subscript is written, it is understood to be 1. In a molecular formula, the subscripts indicate the number of atoms of each element that are present in one molecule. In a chemical formula for an ionic compound, the subscripts represent the lowest whole number ratio of ions in the compound.

∙ 14y agoA number written as a preceding superscript (238U) is a mass number. A number written as a following superscript (O2-) is a charge.

∙ 13y agothe sides should balance each other out, so zero. not ten

What number is never written in the formulas for chemical compounds?
The number ONE is never written in the formula for a chemical coumpound because it will be assumed. ONE is the number!
How do you write the chemical formula for a covalent compound?
By listing the nonmetals in order, generally from left to right on the periodic table, and indicating subscripts as appropriate. For instance, a classic example of a covalently bonded chemical is carbon dioxide, which is written CO2.
Chemical formulas for ionic compounds are written using the least common multiple of the charges on each ion?
True
Are chemical formulas for ionic compounds written using the least common multiple of the charges on each ion?
maybe o.o
What is the number written in front of a chemical formula?
The number written in front of a chemical formula is called the coefficient. This represents the number of molecules of the substance in the chemical formula. For example, 8SO3 tells you that there are 8 molecules of SO3 or sulfur trioxide.
What is 2 cubed in exponential form?
Unfortunately, superscripts and subscripts are not recognized in WikiAnswers. 2 cubed would be written with a superscript 3 following a 2. To indicate that here, we write 2^3.
What is a subscript and where is it located in a chemical formula?
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.

Why can't you balance an equation by changing the subscripts of the reactants or the products?
You can't change the subscript. The subscripts show how the elements/molecules are bonded.--------------------------------------------------------------------------------------------------------The subscripts represent the number of atoms of each element in each chemical formula-if you change the subscripts, you change the compounds the formulas are describing.Source: (e2020)
Oxidation numbers are written as subscripts?
Yes.
What must be known before a chemical equation can be written?
We need to know the reactants and products with their chemical formulas.
What number is never written in the formulas for chemical compounds?

What is meant by subscripts?
A subscript is something written below the line.
What is the difference between a subscript and a coefficant in a chemical formula?
In a chemical formula, a subscript number is used to denote the number of that type of atom, for example H2SO4 has 2 Hydrogens, 1 Sulphur and 4 Oxygens. A superscript number is not usually used in chemical formulae, but is used in rate equations to show the order of reaction with respect to a particular reactant, enzyme or condition.
Can Chemical equations display information concerning the energies involved in a chemical reaction?
The enthalpy change is usually written at the end of the equation. For instance, when hydrogen burns (apologies for the lack of subscripts) 2H2 + O2 = 2H2O Δ H = - 286 kJ per mol
What are Chemical formulas for ethanol?
The molecular formula of ethanol is written as either CH3CH2OH or C2H5OH, and its empirical formula is C2H6O. It is often written as EtOH.
