3. given the following reactants: agi + fe(co3)3  • predict the products • balance the equation • state what type of reaction this is.

Explanation:

The products of chemical reaction will be as follows.

To balance the equation, we will count the number of atoms on both reactant and product sides as follows.

Number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

We will balance the equation by multiplying AgI by 6 on the reactant side and by 2 and by 3 on the product side. Therefore, balanced chemical equation will be as follows.

In this reaction, iron is replaced by silver and carbonate is replaced by iodide. Thus, it is a double displacement reaction.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
