It's a single- replacement reaction so Mg+ 2HCl ➡️ H2+ MgCl2
To balance it, it would be N2 + 3H2 ------> 2NH3.
for c) it would be 2N2 + 6H2 -------> 4NH3
In a reduction reaction,
some electrons are gained by the substance being reduced. The balanced
half-reaction to this would be:
<span>MnO2(s) + 4 H+ (aq)
+ 2e ---> Mn^2+ (aq) + 2 H2O
(aq)</span>
<span>It is called balanced reaction
since the number of each element in the left side is equal to the number of
each element on the right side.</span>
Answer:
0,33atm
Explanation:
For the reaction:
NH₄HS(s) ⇌ H₂S(g) + NH₃(g)
kp is defined as:
kp = 0.11 = P(H₂S) P(NH₃) <em>(1)</em>
Where P(H₂S) and P(NH₃) are partial pressures of each compound.
In equilibrium, if in your system the only addition is of NH₄HS(s), the partial pressures and the concentration of each compound are:
NH₄HS: I - x
<em>-Where I is an initial concentration that is not relevant for the problem and x is the </em>NH₄HS<em> that reacts-</em>
H₂S(g): x
NH₃(g): x
Replacing in (1):
0.11 = X×X
0.11 = X²
<em>0.33 = X</em>
That means P(NH₃) is <em>0.33 atm</em>
<em></em>
I hope it helps!
