Solving the Equations and Identifying the Reaction Types

To solve the given equations and identify the reaction types, let's break down each equation and analyze them one by one:

1. Ca + P: - This equation represents the reaction between calcium (Ca) and phosphorus (P). - The reaction type is a synthesis reaction, where two elements combine to form a compound. - The balanced equation for this reaction is: Ca + P → CaP.

2. Fe(OH)3 + CaCl2: - This equation represents the reaction between iron(III) hydroxide (Fe(OH)3) and calcium chloride (CaCl2). - The reaction type is a double displacement reaction, where the cations and anions of two compounds switch places. - The balanced equation for this reaction is: Fe(OH)3 + 3CaCl2 → FeCl3 + 3Ca(OH)2.

3. H2SO4 + CuO: - This equation represents the reaction between sulfuric acid (H2SO4) and copper(II) oxide (CuO). - The reaction type is a double displacement reaction, where the cations and anions of two compounds switch places. - The balanced equation for this reaction is: H2SO4 + CuO → CuSO4 + H2O.

4. HNO3 + Cu: - This equation represents the reaction between nitric acid (HNO3) and copper (Cu). - The reaction type is a single displacement reaction, where an element replaces another element in a compound. - The balanced equation for this reaction is: 3HNO3 + Cu → Cu(NO3)2 + 2H2O + NO.

5. Hg(NO3)2 + K: - This equation represents the reaction between mercury(II) nitrate (Hg(NO3)2) and potassium (K). - The reaction type is a single displacement reaction, where an element replaces another element in a compound. - The balanced equation for this reaction is: 2K + Hg(NO3)2 → 2KNO3 + Hg.

6. H2O: - This equation represents the decomposition of water (H2O). - The reaction type is a decomposition reaction, where a compound breaks down into its constituent elements. - The balanced equation for this reaction is: 2H2O → 2H2 + O2.

Please note that the given equations may not represent a complete chemical reaction sequence, as some reactants or products may be missing. It is important to have a complete set of reactants and products to accurately determine the reaction types and balance the equations.
