Here’s the math for your answer, which is 3.3 L HCl
Answer:
0.02 tons of NO produced when 4 tons of coal is burned
Explanation:
From the given,
Chemical formula of coal = ![C_{134}H_{96}O_{9}NS](https://tex.z-dn.net/?f=C_%7B134%7DH_%7B96%7DO_%7B9%7DNS)
Molecular mass of coal = ![(134\times12)+(9\times1)+(9\times16)+14+32\,=1906.1gm](https://tex.z-dn.net/?f=%28134%5Ctimes12%29%2B%289%5Ctimes1%29%2B%289%5Ctimes16%29%2B14%2B32%5C%2C%3D1906.1gm)
Let’s calculate the mass of nitrogen in coal
![Percentage\,weight\,of\,nitrogen=\frac{Mass\,of\,nitrogen}{Molecular\,mass\,of coal}](https://tex.z-dn.net/?f=Percentage%5C%2Cweight%5C%2Cof%5C%2Cnitrogen%3D%5Cfrac%7BMass%5C%2Cof%5C%2Cnitrogen%7D%7BMolecular%5C%2Cmass%5C%2Cof%20coal%7D)
![Percentage\,weight/,of/,nitrogen=\frac{14}{1906.1}=0.73%](https://tex.z-dn.net/?f=Percentage%5C%2Cweight%2F%2Cof%2F%2Cnitrogen%3D%5Cfrac%7B14%7D%7B1906.1%7D%3D0.73%25)
Amount of coal burnt = 4tons
Amount of NO produced by burning 4tons = ![4\,tons\,of\,coal\times \frac{0.73tons}{100\,tons\,of\,coal}=0.0292\,tons](https://tex.z-dn.net/?f=4%5C%2Ctons%5C%2Cof%5C%2Ccoal%5Ctimes%20%5Cfrac%7B0.73tons%7D%7B100%5C%2Ctons%5C%2Cof%5C%2Ccoal%7D%3D0.0292%5C%2Ctons)
This nitrogen is converted into NO by reacting with atmospheric oxygen.
Answer:
ⁿₐX => ²¹⁸₈₄Po
Explanation:
Let ⁿₐX be the isotope.
Thus, the equation can be written as follow:
²²²₈₆Rn —> ⁴₂α + ⁿₐX
Next, we shall determine the value of 'n' and 'a'. This can be obtained as follow:
222 = 4 + n
Collect like terms
222 – 4 = n
218 = n
Thus,
n = 218
86 = 2 + a
Collect like terms
86 – 2 = a
84 = a
Thus,
a = 84
ⁿₐX => ²¹⁸₈₄Po
²²²₈₆Rn —> ⁴₂α + ⁿₐX
²²²₈₆Rn —> ⁴₂α + ²¹⁸₈₄Po
Answer:
1.78 × 10²⁶ Atoms
Explanation:
Relation between number of molecules and moles is,
No. of Molecules = Moles × 6.022 × 10²³ Molecules/mol
No. of Molecules = 99 mol × 6.022 × 10²³ Molecules/mol
No. of Molecules = 5.96 × 10²⁵ Molecules
Also, In CO₂ Molecule there are 3 atoms.
So,
No. of atoms = 5.96 × 10²⁵ Molecules × 3
No. of atoms = 1.78 × 10²⁶ Atoms
Answer:
chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.
