Study Notes
Group 1 Metals and Halides
- The formula for the halide of a Group 1 metal with chlorine is MCl, where M is the metal from Group 1.
- The formula for the hydroxide of a Group 1 metal with potassium is not applicable, as potassium is also a Group 1 metal and does not form a hydroxide with another Group 1 metal.
Chemical Reactions
- The correct balanced equation for the reaction between sodium and water is 2Na + 2H2O → 2NaOH + H2.
- The first step in writing a chemical equation is to write the formulas of the reactants and products.
Equations and Formulas
- A chemical equation is used to represent the reactants and products of a chemical reaction.
- The formula for the diatomic molecule of bromine is Br2.
- The formula Cl2 represents the diatomic molecule of chlorine.
- The numbers in front of the formulas in a balanced chemical equation represent the mole ratios of the reactants and products.
Sodium Chloride
- The formula for sodium chloride (NaCl) is based on the combination of a Group 1 metal (sodium) with a halogen (chlorine).
Equation Types
- A word equation is a representation of a chemical reaction using words, such as "sodium reacts with chlorine to form sodium chloride".
- A symbol equation provides information about the reactants, products, and mole ratios of a chemical reaction.
