Using the activity series provided. Which reactants will form products?

Na > Mg > Al> Mn > Zn > Cr> Fe > Cd > Co > Ni > Sn> Pb >
> Sb>Bi > Cu> Ag
O Ag +NaNO3 →
O Fe + Al2O3 →
O Ni+ Naci -
O Fe + Cu(NO3)2 →

To determine which reactants will form products, we need to compare the position of each element in the activity series. Reactants that are higher in the activity series can displace those lower in the series and form products. Let's go through each reaction and determine if products will be formed.

1) Ag + NaNO3:
Ag is higher in the activity series than Na, so Ag can displace Na from NaNO3. Therefore, products will be formed. The balanced chemical equation is:
Ag + NaNO3 -> AgNO3 + Na

2) Fe + Al2O3:
Fe is higher in the activity series than Al, so Fe can displace Al from Al2O3. Therefore, products will be formed. The balanced chemical equation is:
Fe + Al2O3 -> Fe2O3 + Al

3) Ni + NaCl:
Ni is higher in the activity series than Na, so Ni cannot displace Na from NaCl. Therefore, no products will be formed.

4) Fe + Cu(NO3)2:
Fe is lower in the activity series than Cu, so Fe cannot displace Cu from Cu(NO3)2. Therefore, no products will be formed.

In summary:
- Ag + NaNO3 will form products.
- Fe + Al2O3 will form products.
- Ni + NaCl will not form products.
- Fe + Cu(NO3)2 will not form products.

To determine which reactants will form products using the given activity series, you need to compare the activities of the elements involved in each reaction.

1. Ag + NaNO3:
Looking at the activity series, we can see that Ag is higher in the series compared to Na. This indicates that Ag is more reactive than Na. Therefore, Ag will displace Na from NaNO3, resulting in the formation of products. The balanced equation for this reaction is:
2 Ag + 2 NaNO3 → 2 AgNO3 + Na2

2. Fe + Al2O3:
Comparing the activity series, we can see that Fe is above Al. This implies that Fe is more reactive than Al. Fe will displace Al from Al2O3, resulting in the formation of products. The balanced equation for this reaction is:
2 Fe + Al2O3 → 2 FeO + Al

3. Ni + NaCl:
Comparing the activity series, Ni is below Na. This suggests that Ni is less reactive than Na. Therefore, Ni will not displace Na from NaCl, and no reaction will occur between Ni and NaCl.

4. Fe + Cu(NO3)2:
Comparing the activity series, Fe is below Cu. This implies that Fe is less reactive than Cu. Therefore, Fe will not displace Cu from Cu(NO3)2, resulting in no reaction between Fe and Cu(NO3)2.

In summary:
- Ag will form products with NaNO3.
- Fe will form products with Al2O3.
- Ni will not form products with NaCl.
- Fe will not form products with Cu(NO3)2.

You're given a road map. I wouldn't think you could miss it.

What is your problem in knowing how to answer this. If the single metal element listed is above the metal in the compound, the metal in the compound is replaced. Otherwise, no reaction.
Ag +NaNO3 →
Ag is BELOW (less reactive) than Na; therefore, there is no reaction. You do the others. I shall be happy to check your results.
