In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
Is there any structural formula of n ethane and iso ethane like n butane and iso butane?
Yes, the structural formula of n-butane is C4H10 and the structural formula of isobutane (2-methylpropane) is also C4H10. However, for ethane, the formula is C2H6 and there isn't a distinct isomer like isobutane for ethane.
Why is it not possible to change the subscripts to balance the equation?
Changing subscripts in a chemical formula changes the actual chemical species present, leading to a different reaction. Subscripts represent the ratio of elements in a compound and should not be changed to balance chemical equations. Balancing equations is done by adjusting coefficients in front of chemical formulas, not by changing subscripts.
Why is it important to never change the subscript in a chemical formula when balancing a chemical equation?
It is important to never change the subscript in a chemical formula when balancing a chemical equation because subscripts represent the number of atoms of each element in the compound. Changing subscripts would alter the chemical formula and consequently change the identity of the compounds involved in the reaction. Balancing equations involves adjusting coefficients, not subscripts.
What is the chemical formula for ethane burns?
The chemical formula for ethane is C2H6. When ethane burns, it reacts with oxygen to produce carbon dioxide (CO2) and water (H2O) as products. The balanced equation for the combustion of ethane is: 2C2H6 + 7O2 -> 4CO2 + 6H2O.
In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
What do subscripts represent?
Subscripts represent the number of atoms of an element in a molecule. They are written as small numbers to the right of the element symbol in a chemical formula. They indicate the ratio of elements in a compound.
Chemical Formula of Ethane?
Ethane is C2H6.
Is there any structural formula of n ethane and iso ethane like n butane and iso butane?
Yes, the structural formula of n-butane is C4H10 and the structural formula of isobutane (2-methylpropane) is also C4H10. However, for ethane, the formula is C2H6 and there isn't a distinct isomer like isobutane for ethane.
What is the formula of ethane amide?
Ch3-c(=o)-nh2

Subscripts represent the ratio of elements in a compound and should not be changed to balance chemical equations. Balancing equations is done by adjusting coefficients in front of chemical formulas, not by changing subscripts.
Do subscripts represent the relative mass of each type of atom in the compound?
No, subscripts in a chemical formula represent the number of atoms of each element in the compound. The relative mass of each atom is accounted for by the atomic mass of the element found in the periodic table. So, atomic mass, not subscripts, gives you the relative mass of each type of atom in a compound.

It is important to never change the subscript in a chemical formula when balancing a chemical equation because subscripts represent the number of atoms of each element in the compound. Changing subscripts would alter the chemical formula and consequently change the identity of the compounds involved in the reaction. Balancing equations involves adjusting coefficients, not subscripts.
What molecular formulas are an empirical formula?
Any molecular formula where the subscripts do not have a common factor that can divide them all. For example: CH4 (methane) is a molecular formula that is also an empirical formula because there is no number (other then one) that can divide both the 4 and the 1. Take ethane as another example. It hasn't the empirical formula which is similar to the molecular formula.
What are the subscripts for the formula unit CaO?
No subscripts are needed: The formula unit for calcium oxide contains one calcium cation with a charge of +2 and one oxide anion with a charge of -2.
What is ethane's hydrocarbon formula?
Ethane ; H3CCH3 NB Methane ' CH4 Propane ; CH3CH2CH3 Butane ; CH3CH2CH2CH3 et seq.
