AP Chemistry free response :// single replacement reactions What is the purpose of this experiment? to determine the order of activity of four metals: iron, copper, zinc, and magnesium by studying the single replacement reactions Single Replacement Reactions Reminder – Goggles must be worn at all times in the lab! PRE-LAB DISCUSSION: Single replacement reactions are reactions in which an element in pure form competes for a place with an ion or atom in a compound. One type of single replacement reaction is the replacement of hydrogen in acids by active metals, A single displacement reaction occurs when an element reacts with a compound in a chemical reaction. During the reaction, the element replaces the anion or the cation in the compound. Complete and balance the following single replacement reactions:
Classify reactions as single-replacement chemical reactions. Use numbers to write balanced equations for single-replacement reactions. Sequence metals into an activity series. Process Skills Acquiring and analyzing information, collecting and interpreting data, drawing a conclusion, hypothesizing, measuring and using numbers, observing and Writing Equations for Reactions. Write the correct formulas for each reactant and place a yield arrow (→) after the last reactant. Identify the reaction type – single Pour three teaspoons of dry yeast and two teaspoons of sugar into a bottle. Slowly pour hot water into the bottle. Put the balloon over the bottle and wait for half an hour. The liquid starts to foam, and the balloon inflates. Yeast is a microscopic fungus that consumes sugar and releases carbon diox:// List four types of single-replacement reactions and three types of double-replacement reactions. SINGLE: (1) replacement of a metal in a compound by another metal (2) replacement of hydrogen in water by a metal (3) replacement of hydrogen in an acid by a metal (4) replacement of halogens DOUBLE: (1) formation of a precipitate (2) formation of a
Single Replacement Reactions In Part A of this lab we will examine single replacement reactions. This is one type of oxidation-reduction reaction, or redox reaction, because it occurs via a transfer of electrons. Single replacement reactions have the general form: A + BC → B + AC Author of Establishing the Relative Reactivity of Halogens and Halide Ions, Determining the Empirical Formula of Magnesium Oxide, Separating and Determining the Mass of Calcium Ion in a Calcium-Enriched Tablet, Resolving a Two Component Mixture, Observing Single Replacement Reactions, Determiming Density, Observing Doulbe Replacement Reactors 1.

For example, the formula “HCl” can be used for hydrogen chloride gas, HCl(g), so to indicate hydrochloric acid, one must specify HCl(aq). ~kimld/chmLab_files/
