QuestionAnswer
How do you write a word equation? write the names of the reactants separated by a plus sign on the left of the arrow and the names of the products separated by a plus sign on the right
how do you write a skeleton equation? write the formulas of the reactants to the left of the yields sign and the formulas of the products to the right
describe the steps in writing a balanced chemical equation write the skeleton equation with the correct formulas of the reactants on the left and the correct formulas of the products on the right, then balance the equation using coefficients so that it obeys the law of conservation of mass
five types of chemical reactions combination, decomposition, single-replacement, double-replacement, and combustion
what are the keys to predicting the products of the five general types of reactions? the number of elements and/or compunds reacting
what are the three types of products that result from double-replacement reactions? gas, precipitate, and molecular compound
what is a net ionic equation? shows only those particles involved in the raction and is balanced with respect to both mass and charge
how can you predict the formation of a precipitate in a double-replacement reaction? use the general rules for solubility of ionic compounds
what is the function of an arrow in a chemical equation? the arrow separates the reactants from the products and indicates a reaction that progresses in a forward direction
what is the purpose of a catalyst it speeds up a chemical reaction
what is a characteristic of every combination reaction? a single product
what is a distinguishing feature of every decomposition reaction? a single reactant
what substance is common to all combustion reactions? oxygen
what is a spectator ion an ion that does not participate in the reaction.
