7. An exothermic reaction
8. The bonds are forming
Answer:
magnesium chloride
Explanation:
Complete step-by-step answer:
The remaining ions combine to produce the salt of neutralisation. The salt is magnesium chloride. The chemical formula for the compound is $MgC{{l}_{2}}$.
Iv: the red and blue kryptonite
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>
