Answer from: karicloou1332

For A: The elements having similar chemical properties as of iodine are fluorine and bromine.

For B: The elements having similar chemical properties as of barium are magnesium and calcium

For C: The elements having similar chemical properties as of iron are ruthenium and osmium.

Explanation:

In a periodic table, elements are arranged in 18 vertical columns known as groups and 7 horizontal rows known as periods.

Elements arranged in a group show similar chemical properties because of the presence of same number of valence electrons.

For A: Iodine

Iodine is present in Group 17 of the periodic table. The elements present in this group are Fluorine, Chlorine, Bromine, Iodine and Astatine.

The elements having similar chemical properties as of iodine are fluorine and bromine.

For B: Barium

Barium is present in Group 2 of the periodic table. The elements present in this group are Beryllium, Magnesium, Calcium, Strontium, Barium and Radium.

The elements having similar chemical properties as of barium are magnesium and calcium

For C: Iron

Iron is present in Group 8 of the periodic table. The elements present in this group are Iron, Ruthenium, Osmium and Hassium.

The elements having similar chemical properties as of iron are ruthenium and osmium.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

Answer from: Quest

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃ → 3 nicl₂ + 2 albarium and copper bromideba + cubr → no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn → znso₄ + na
