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, $H_{2}CO_{3}$ (carbonic acid) decomposes into $CO_{2}$ (carbon dioxide) and $H_{2}O$ (water). This is a decomposition reaction, where a single compound breaks down into two or more simpler substances.<br /><br />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.<br /><br />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.<br /><br />8. The correct answer is D. AgCl. In the given reaction, $NaCl$ (sodium chloride) reacts with $AgNO_{3}$ (silver nitrate) to form $NaNO_{3}$ (sodium nitrate) and $AgCl$ (silver chloride). According to solubility rules, $AgCl$ is insoluble in water, while the other compounds are soluble.<br /><br />9. The correct answer is B. $BaSO_{4}$. According to solubility rules, $BaSO_{4}$ (barium sulfate) is insoluble in water, while the other compounds are soluble.
