Answer:
Five molecules of oxygen.
Explanation:
Hello,
In this case, considering the given chemical reaction, we must write a five before the oxygen in order to equal the number of oxygen atoms at both the right and left side (ten) so phosphorous remain the same (4):
![P_4(s) + 5 O_2(g)\rightarrow P_4O_{10}(s)](https://tex.z-dn.net/?f=P_4%28s%29%20%2B%205%20O_2%28g%29%5Crightarrow%20%20P_4O_%7B10%7D%28s%29)
It means that five molecules of oxygen (O₂) are needed to form one molecule of tetraphosphorous decaoxide (P₄O₁₀).
Best regards.

Answer:
- 1.22KJ
Explanation:
First we put down the equation of the reaction;
NH4Cl(s)<-------->NH3(g) + HCl(g)
The equilibrium constant K is obtained from;
K= P(NH3) × P(HCl)
Where;
P(NH3)= pressure of ammonia
P(HCl)= pressure of hydrogen chloride gas
Pure solids and liquids are not included in the equilibrium constant expression. This is because they do not affect the reactant amount at equilibrium in the reaction, so they are disregarded and kept at 1. Remember that the activity, a, of any solid or liquid in a reaction is equal to 1. Hence [NH4Cl]= 1
K= 1.03 × 1.18 = 1.22
∆G° = -RTlnK
R= 8.314 JK-1mol-1
T= 465°C +273= 738K
K= 1.22
lnK= ln(1.22)= 0.19885
∆G= -(8.314 ×738 ×0.19885)
∆G= -1220.1 J
∆G= -1.22×10^3 J
∆G= - 1.22KJ
