Question

Cu(OH)2> Cu (NO3)2> Cu> CuO> CuCl2

Answer 1

Cu(OH)₂ → Cu(NO₃)₂ → Cu → CuO → CuCl₂

1) Cu(OH)₂ + 2HNO₃ → Cu(NO₃)₂ + H₂O

2) Cu(NO₃)₂ + 2Na → 2NaNO₃ + Cu

3) 2Cu + O₂ → 2CuO

4) CuO + 2HCl → CuCl₂ + H₂O

Answer 2

1) Cu(OH)2 + 2HNO3 = Cu(NO3)2 + H2O

2) Cu(NO3)2 + 2Na = 2NaNO3 + Cu

3) 2Cu + O2 = 2CuO

4) CuO + 2HCl = CuCl2 + H2O

Answer 3

The notation you provided represents a series of chemical reactions and the relative reactivity of different copper compounds. The ">" symbol typically denotes a greater reactivity or preference for a particular reaction. The order you provided suggests that the reactivity decreases as you move from left to right. Let's break it down:

1. Cu(OH)2 > Cu(NO3)2: This notation implies that copper hydroxide (Cu(OH)2) is more reactive than copper nitrate (Cu(NO3)2). In a chemical context, "more reactive" means that Cu(OH)2 is more likely to undergo a reaction or change compared to Cu(NO3)2 under certain conditions.

2. Cu(NO3)2 > Cu: This suggests that copper nitrate (Cu(NO3)2) is more reactive than elemental copper (Cu). In other words, Cu(NO3)2 is more likely to participate in chemical reactions compared to pure copper metal.

3. Cu > CuO: This indicates that elemental copper (Cu) is more reactive than copper oxide (CuO). In general, metals tend to be more reactive in their elemental form compared to their oxide forms.

4. CuO > CuCl2: This shows that copper oxide (CuO) is more reactive than copper chloride (CuCl2). Once again, this suggests that CuO is more likely to undergo chemical reactions compared to CuCl2.

Keep in mind that this reactivity series is a general trend and may not hold true for all reaction conditions. Reactivity can be influenced by factors such as temperature, pressure, and the presence of other substances or catalysts. Additionally, some reactions might be more complex and not solely depend on the reactivity of the substances involved.
