Can a chemical formula represent ions?
Yes, chemical formulas can represent ions, such as NH4+​ for the ammonium ion.
How do you write a chemical formula?
Identify the elements, balance the charges using valency, and use parentheses for polyatomic ions.
What are the types of chemical formulas?
The main types include molecular formula, empirical formula, and structural formula.
Why are chemical formula important?
Chemical formulas help understand the composition of compounds, write chemical equations, and represent ions and radicals.
What is a chemical formula?
A chemical formula is a symbolic representation that indicates the elements in a compound and the ratio of atoms.
How do you determine the chemical formula of an ionic compound?
To determine the formula of an ionic compound, balance the charges of the cations (positive ions) and anions (negative ions) so that the overall charge of the compound is neutral.
What is the difference between an empirical formula and a molecular formula?
A chemical formula represents the composition of a single compound, whereas a chemical equation represents a chemical reaction, showing how reactants are converted into products.
How is a chemical formula different from a chemical equation?
