Identify reaction 5 __ 4. H_(2)+O_(2)arrow H_(2)O 5. Al+NiBr_(2)arrow AlBr_(3)+3NI Single repalcement Synthesis Double Decomposition Combustion Decomposition

To identify the type of reaction for each given equation, let's analyze them step by step:1. - This reaction involves a single compound breaking down into two different products. This is a classic example of a **decomposition** reaction.2. - Here, an acid (HCl) reacts with a base (NaOH) to form salt (NaCl) and water (H2O). This is a typical **acid-base reaction**, which can also be categorized under **double replacement** reactions in a broader sense because ions exchange partners.3. - This reaction shows a single metal (Mg) replacing the hydrogen in hydrochloric acid (HCl), resulting in magnesium chloride (MgCl2) and hydrogen gas (H2). This is a **single replacement** reaction.4. - Two elements combine to form a single compound, water (H2O), in this case. This is a **synthesis** reaction, where simpler substances combine to form a more complex substance.5. - In this reaction, aluminum (Al) replaces nickel (Ni) in nickel bromide (NiBr2), resulting in aluminum bromide (AlBr3) and nickel (Ni). This is also a **single replacement** reaction, where one element is replaced by another in a compound.**Identifying Reaction 5:** - Given the context and the nature of the reaction, where aluminum (Al) displaces nickel (Ni) in a compound, the accurate classification for this reaction is **Single Replacement**.**Accurate Answer:** Single Replacement
