Balancing And Types Of Chemical Reactions Worksheet A balanced chemical equation gives the number and type of atoms participating in a reaction the reactants products and direction of the reaction Balancing an unbalanced equation is mostly a matter of making certain mass and charge are balanced on the reactants and products side of the reaction arrow

Balancing Equations The chemical equation described in section 4 1 is balanced meaning that equal numbers of atoms for each element involved in the reaction are represented on the reactant and product sides This is a requirement the equation must satisfy to be consistent with the law of conservation of matter 1 In reactions dealing solely with ions one can leave the polyatomic ions as groups for ease of balancing 2 In reactions dealing with only ions and water water can be considered as a combination of a hydrogen ion and hydroxide ion 3
Chemical Equations and the Law of Conservation of Matter In the previous section the reaction between hydrogen gas and oxygen gas to produce water in the gaseous phase was shown as a chemical equation H 2 g O 2 g H 2 O g At the molecular level the reaction would look something like this Notice that there are two oxygen atoms on the left hand side of the equation and only Chemical reactions in which electrons are transferred are called oxidation reduction or redox reactions Oxidation is the loss of electrons Reduction is the gain of electrons Oxidation and reduction always occur together even though they can be written as separate chemical equations 5 6 Recognizing Redox Reactions 5 7 Net Ionic Equations
