What are the five types of chemical reactions?️️combination, decomposition, singlereplacement, double-replacement, combustion What are the keys to predicting the products of the five general types of reactions?️️the number of elements and/or compounds reacting Classify each reaction and balance the equations.️️a. C3H6 + O2 > CO2 + H2O b. Al(OH)3 > Al2O3 + H2O c. Li + O2 > Li2O d. Zn + AgNO3 > Ag + Zn(NO3)2 a. combustion: 2 C3H6 + 9 O2 > 6 CO2 + 6 H2O b. decomposition: 2 Al(OH)3 > Al2O3 + 3 H2O c. combination: 4 Li + O2 > 2 Li2O d. single-replacement: Zn + 2 AgNO3 > 2 Ag + Zn(NO3)2 Which of the five general types of reaction would most likely occur, given each set of reactants? What are the probable products?️️a. an aqueous solution of two ionic compounds b. a single compoundbc. two elements d. oxygen and a compound of carbon and hydrogen a. double replacement; two different compounds b. decomposition; two or more elements and/or compounds c. combination; a compound d. combustion; carbon dioxide and water Complete and balance an equation for each reaction.️️a. CaI2 + Hg(NO3)2 > (HgI2 precipitates.) b. Al + Cl2 > c. Ag + HCl > d. C2H2 + O2 > e. MgCl2 > a. CaI2 + Hg(NO3)2 > HgI2 + Ca(NO3)2 b. 2 Al + 3 Cl2 > 2 AlCl3 c. no reaction d. 2 C2H2 + 5 O2 > 4 CO2 + 2 H2O e. MgCl2 > Mg + Cl2 What are the three types of products that result from double-replacement reactions?️️gas, precipitate, and molecular compound How can you predict the formation of a precipitate in a double-replacement reaction?️️You can predict the formation of a precipitate by using the general rules for solubility for ionic compounds. What are the properties of acids and bases?️️Acids- Sour, pH>7 Bases- Bitter, pH<7 How did Arrhenius define an acid and a base?️️Arrhenius said that acids are hydrogencontaining compounds that ionize to yield hydrogen ions (H+) in aqueous solution. He also said that bases are compounds that ionize to yield hydroxide ions (OH−) in aqueous solution. How are acids and bases defined by the Bronsted-Lowry theory?️️The Brønsted-Lowry theory defines an acid as a hydrogen-ion donor, and a base as a hydrogen-ion acceptor What is the Lewis theory of acids and bases?️️Lewis proposed that an acid accepts a pair of electrons during a reaction, while a base donates a pair of electrons a. What is a conjugate acid-base pair? b. Write equatio
