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;

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

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 ------------------- ?

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

Why is this mars landing a new era for space exploration

Artemon [7]

Answer: The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet's evolution, and preparing for future human exploration. Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind.

The term “ average atomic mass “ is a ______average so is calculator different Lee from a normal average

hoa [83]

Average atomic mass of an element is a sum of the product of the isotope mass and its relative abundance.

For example: Chlorine has 2 isotopes with the following abundances

Cl(35): Atomic mass = 34.9688 amu; Abundance = 75.78%

Cl(37): Atomic mass = 36.9659 amu; Abundance = 24.22 %

Average atomic mass of Cl = 34.9688(0.7578) + 36.9659(0.2422) =

= 26.4993 + 8.9531 = 35.4524 amu

Thus, the term “ average atomic mass “ is a weighted average so it is calculated differently from a normal average
