Study Notes
Chemical Equations Overview
- Chemical formulas provide a shorthand representation of compounds formed by combining two or more elements.
- Subscripts indicate the number of atoms of each element in a compound; they cannot be altered during balancing to maintain the identity of the substance.
Reactants and Products
- Reactants are the initial chemicals that engage in a chemical reaction, leading to the formation of new products.
- Products are the new substances generated from the reaction, resulting from the transformation of reactants.
Key Symbols in Chemical Equations
- The yields symbol indicates the direction of the reaction, acting similarly to an equal sign to separate reactants from products.
- Coefficients are multipliers applied to subscripts to determine the total number of atoms in a compound; they can be changed when balancing chemical equations, unlike subscripts.
