6) A 14.5 g sample of sodium chloride reacts with excess fluorine gas according to

Ann [662]

The mass of chlorine gas produced by 14.5 grams of sodium chloride is 10.42 g.

The mass of chlorine gas produced by 14.5 grams of sodium chloride is 8.81 g.

The given parameters;

<em>mass of the sodium chloride, = 14.5 g</em>
<em>2NaCl(s) + F2(g) → 2NaF(s) + Cl2(g)</em>

<em />

In the reaction above, we can deduce the following;

molecular mass of 2Nacl = 2(58.44) = 116.88 g

molecular mass of 2NaF = 2(42) = 84 g

molecular mass of Cl2 = 71 g

The mass of sodium fluoride produced by 14.5 grams of sodium chloride is calculated as follows;

116.88 g of NaCl --------------- 84 g of NaF

14.5 g of NaCl ------------------- ?

$= \frac{84 \times 14.5}{116.88} \\\\= 10.42 \ g$

The mass of chlorine gas produced by 14.5 grams of sodium chloride is calculated as follows;

116.88 g of NaCl --------------- 71 g of Cl2

14.5 g of NaCl ------------------- ?

$= \frac{14.5 \times 71}{116.88} \\\\= 8.81 \ g$

Alchemists were medieval scholars and philosophers who were the forerunners of modern-day chemists. many tried repeatedly to tra

AlladinOne [14]

Answer is: because they were using simple chemical reactions to transform elements, but that is possible only with nuclear reactions, which in that time were not possible to conduct.

Nuclear reactions can produce new elements, because number of protons and neutrons is changed, lead and gold have different atomic and mass numbers.

The electrons of an atom participates in a chemical reaction, chemical reactions involve the rearrangement of electrons, because there is transfer, loss, gain and sharing of electrons in chemical reactions, new elements are not formed.
