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:
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
The amount of KCl that would be formed will be 478.8 grams
<h3>Stoichiometric calculations</h3>
From the equation of the reaction, the mole ratio of K to 
is 2:1.
Mole of 309 g potassium = 309/39 = 7.92 moles
Mole of 228 g Cl2 = 228/71 = 3.21 moles
Thus, potassium is in excess while Cl2 is limiting.
Mole ratio of Cl2 and KCl = 1:2
Equivalent mole of KCl = 3.21 x 2 = 6.42 moles
Mass of 6.42 moles KCl = 6.42 x 74.55 = 478.8 grams

Answer:
random internal motion of atoms and molecule
Explanation:
The primary cause of diffusion is the random internal motion of atoms and molecules.
Randomness of atoms and molecules results in diffusion.
- Diffusion is the movement of particles from a region of high concentration to that of lower concentration.
- Substances often tend to spread out over the concentration gradient.
- Therefore, they have this propensity to be randomized.
