Anthracite is a form of carbonized ancient plants; the hardest and cleanest-burning of all the coals.

Bituminous is a form of coal that is characterized by mineral pitch; a black, tarry substance, burning with a bright flame.

Lignite is a low grade brownish coal.

Peat is a form of coal formed of dead but not fully decayed plants found in bog areas, often burned as fuel.

From the definitions given above, one can categorically say the most heated is in a descending order. And According to the Question, most heated is most valuable.

How many chlorine atoms would be in 6.02 X 10^23 units of gold III chloride
Pepsi [2]

Answer:

The number of chlorine atoms present in 6.02 \times 10^{23} units of gold III chloride is 18.066 \times 10^{23}

Explanation:

Formula of Gold (III) chloride: AuCl_{3}

<em>Avogadro Number</em> : Number of particles present in <u>one mole</u><u> </u>of a substance.

{N_{0}} =6.022 \times 10^{23}

Using,

n(moles)=\frac{Given\ number\ of\ particles}{N_{0}}

n =\frac{6.02\times 10^{23}}{6.022\times 10^{23}}

= 1 mole(0.9999 , nearly equal to 1 )

The given Gold III chloride sample is 1 mole in amount.

6.022 \times 10^{23}  = 1 mole of AuCl_{3}

In this Sample,

1 mole of AuCl_{3} will give = 3 mole of Chlorine atoms

1 mole of Cl contain = 6.022 \times 10^{23}

3 mole of Cl contain = 6.022 \times 10^{23}\times 3

3 mole of Cl contain =18.066 \times 10^{23}

So,

The number of chlorine atoms present in 6.02 \times 10^{23} units of gold III chloride is 18.066 \times 10^{23}
