5. Which type of reaction is the following: H_(2)CO_(3)arrow CO_(2)+H_(2)O A. Double Replacement B. Combustion C. Decomposition D. Synthesis 6. Which of the following is NOT a driving force for a reaction? A. Formation of a liquid B. Formation of a gas C. Formation of a solid D. Transfer of electrons 7. If a compound fully ionizes in solution it is said to be A. Insoluble B. Soluble C. Non-electrolyte D. Not dissolved According to the following reaction which product is insoluble in water? NaCl+AgNO_(3)arrow NaNO_(3)+AgCl A. NaCl B. AgNO_(3) C. NaNO_(3) D. AgCl sed on the solubility rules , which of the following compounds A. PbBr_(2) B. BaSO_(4) C. NH_(4)F D. CaSO_(4)

5. The correct answer is C. Decomposition. In the given reaction, (carbonic acid) decomposes into (carbon dioxide) and (water). This is a decomposition reaction, where a single compound breaks down into two or more simpler substances.6. The correct answer is D. Transfer of electrons. The driving forces for a reaction are the formation of a liquid, the formation of a gas, and the formation of a solid. The transfer of electrons is not a driving force for a reaction.7. The correct answer is B. Soluble. If a compound fully ionizes in solution, it means that it dissolves completely and forms ions. This indicates that the compound is soluble in the solvent.8. The correct answer is D. AgCl. In the given reaction, (sodium chloride) reacts with (silver nitrate) to form (sodium nitrate) and (silver chloride). According to solubility rules, is insoluble in water, while the other compounds are soluble.9. The correct answer is B. . According to solubility rules, (barium sulfate) is insoluble in water, while the other compounds are soluble.
