Will platinum (pt) metal react with a lead(ii) nitrate solution?

1 answer:

5 0

To answer this question, we must first look at the reactivity series table. From the table, we can see that those which are located above are the most reactive while those below are less reactive. Which means that elements cannot replace those elements which are above them.

From the series, platinum is below lead, hence there will be no reaction.

Answer:

No reaction

In salt, what is the nature of the bond between sodium and chlorine? in salt, what is the nature of the bond between sodium and

kifflom [539]

A chemical bond that involves the transfer of electrons from a metal to a nonmetal and thus forms ions and the atoms in the molecule are attracted towards each other through electrostatic force of attraction are said be ionic bond. In short, the bond formed between the two oppositely charged ions.

In salt, the compound formed between sodium and chlorine is sodium chloride having molecular formula $NaCl$ where sodium is a metal and chlorine is the non-metal. The formation of the compound takes place by transfer of an electron from sodium thus forming a cation of formula $Na^{+}$ to chlorine which gains electron and thus results in an anion formation having formula $Cl^{-}$ . The force of attraction between these oppositely charged ions that helds them together and results in formation of $NaCl$ compound is electrostatic force of attraction.

Hence in salt, the nature of bond between sodium and chlorine is ionic.

In ironmaking, iron metal can be separated from iron ore (Fe2O3) by heating the ore in a blast furnace in the presence of coke,

mel-nik [20]

The limiting reactant is iron ore, the theoretical yield of iron metal is 701.344 kg, and the theoretical yield of carbon dioxide is 413.292 kg.

<h3>Stoichiometric problem</h3>

From the equation of the reaction:

$2 Fe_2O_3(s) + 3 C(s) --- > 4 Fe(s) + 3 CO_2(g)$

The mole ratio of iron ore to carbon is 2:3.

Mole of 1000 kg of iron ore = 1000000/159.69

= 6,262 moles

Mole of 120 kg carbon = 120000/12

= 10,000 moles

Thus, it appears that the carbon is in excess while the iron ore is limited in availability.

The mole ratio of the iron ore and the iron produced is 1:2. Thus, the equivalent number of moles of iron produced will be:

6,262 x 2 = 12,524 moles

Mass of 12,524 moles of iron = 12,524 x 56

= 701,344 g or 701.344 kg

Thus, the theoretical yield of iron is 701.344 kg.

The mole ratio of the iron ore and the carbon dioxide produced is 2:3. The equivalent mole of carbon dioxide produced will be:

6,262 x 3/2 = 9,393 moles

Mass of 9,393 moles carbon dioxide = 9,393 x 44

= 413,292 or 413.292 kg

The theoretical yield of carbon dioxide is, therefore, 413.292 kg.
