Answer 2

I will try to answer your question in detail. You need to match the initial substances with the products of the reaction. Here are some facts that might help you:

- A) AICI3 + AgNO3 → This is a double displacement reaction, where the cations and anions of two ionic compounds exchange places. The products are AgCI and AI(NO3)3. AgCI is a precipitate, which means it is insoluble in water and forms a solid. AI(NO3)3 is soluble in water and remains as ions in the solution. Therefore, the correct match for this reaction is 4) AgCI + AI(NO3)3. - B) Can(HCO3)2 + Can(OH)2 → This is a decomposition reaction, where a compound breaks down into simpler substances. The products are CaCO3 and H2O. CaCO3 is a precipitate, which means it is insoluble in water and forms a solid. H2O is a liquid. Therefore, the correct match for this reaction is 3) CaCO3 + H2O. - C) Current + HNO3(разб.) → This is a single displacement reaction, where a metal replaces another metal in a compound. The products are Cu(NO3)2 and H2. Cu(NO3)2 is soluble in water and remains as ions in the solution. H2 is a gas, which means it escapes from the solution. Therefore, the correct match for this reaction is 2) Cu(NO3)2 + H2↑. - D) KNO3 + H2SO4(конц) → This is an acid-base reaction, where a salt and an acid react to form another salt and another acid. The products are KHSO4 and HNO3. KHSO4 is soluble in water and remains as ions in the solution. HNO3 is a strong acid, which means it dissociates completely in water. Therefore, the correct match for this reaction is 6) KHSO4 + HNO3.

I hope this helps you understand the reactions better.
