There are 191,017 atoms across the 12 moles of sulfur
The correct answer is option (a) i.e. the equilibrium constant is 0.0167
<span>
We know,
The equilibrium constant is kc = Concentration of product/ concentartion of reactants,
kc = [C][D] / [A][B],
Now,
kc= [4.00]*[4.0] / ( [9.60] * [10.00] ) = 0.166 </span>≈ 0.167
Thus, the equilibrium constant is 0.0167
Answer:
In a salt halogen element have negative charge if it gain an electron.
Explanation:
Fluorine,chlorine, bromine and iodine belongs to the family of halogen elements.These elements have high tendency to acquire electron due their high electronegativity.
When a halogen element forms a salt for example potassium chloride(KCl), the Cl or chlorine is a halogen element which get negative charge when it gains or acquires an electron.
Answer is: 2065.15 kJ.
Balanced chemical reaction: 4NH₃ + 5O₂ → 4NO + 6H₂O<span>, ΔHrxn=−906 kJ.
m(</span>NH₃) = 155 g.
n(NH₃) = m(NH₃) ÷ M(NH₃).
n(NH₃) = 155 g ÷ 17 g/mol.
n(NH₃) = 9.118 mol.
Make proportion: 4 mol(NH₃) : 906 kJ = 9.118 mol : Q.
Q = 906 kJ · 9.118 mol / 4 mol.
Q = 2065.15 kJ.
