Answer:
The correct answer is option b.
Explanation:

Mass of coal burned =
metric ton = 1.00\times 10^6\times 10^3 kg=10^9 kg[/tex]
1 metric ton = 
Molar mass of coal :

1 g = 0.001 kg
Moles of coal ,n :
If 2 moles of coal on combustion gives 270 moles of carbon dioxide than n moles of coal will give;
of carbon dioxide.
Molar mass of carbon dioxide gas = 44 g/mol = 0.044 kg/mol
Mass of
of carbon dioxide:

This can tell you alot. its about what you are learning but it can affect the way that the substance bonds to others or how high the boiling and melting point are. hope this helps some.
In group theory, a branch of mathematics, the term order is used in two unrelated senses:
<span><span>The order of a group is its cardinality, i.e., the number of elements in its set. Also, the order, sometimes period, of an element a of a group is the smallest positive integer m such that <span>am = e</span> (where e denotes the identity element of the group, and am denotes the product of m copies of a). If no such m exists, a is said to have infinite order.</span><span>The ordering relation of a partially or totally ordered group.</span></span>
This article is about the first sense of order.
The order of a group G is denoted by ord(G) or | G | and the order of an element a is denoted by ord(a) or | a |.
For the answer to the question above asking, e<span>ach row in the periodic table corresponds to one energy level in an atom.
The answer is true.
