Two samples of potassium iodide are decomposed into their constituent elements. the first sample produced 13.0 g of potassium and 42.3 g of iodine. if the second sample produced 24.4 kg of potassium, how many kg of iodine were produced?

79.46kg of Iodine will be produced in the reaction.

These are substances which can't be broken down into smaller matter and is usually very pure.

Atomic mass of potassium =39 g/mol

Atomic mass of iodine = 127 g/mol

Moles of K produced = ?

Moles of I produced =  ?

The moles of K produced = mass/molar mass

= 13/39

= 0.33

Moles of I produced=  mass/molar mass

=42.3/127

= 0.33

Mole ratio of K:I = 1:1

The moles of K produced by second sample = mass/molar mass =

= 24.4 × 10³ / 39 = 0.626mol

The mass of Iodine produced = moles X atomic mass

= 0.626  X 127= 79.46 kg

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.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
