<span> Au</span>₂(SeO₄)₃
O = -2 × 4 = -8
Se = + 6
So,
(+6 - 8) = -2
Means (SeO₄) contains -2 charge, Now multiply -2 by 3
-2 ₓ 3 = -6
Means,
Au₂ + (-6) = 0
Au₂ = +6
Or,
Au = 6 / 2
Au = +3
Result:
Au = +3
Se = +6
O = -2
Ni(CN)₂
Cyanide (CN⁻) contains -1 charge,
So,
N = -3
C = +2
Then,
Ni + (-1)₂ = 0
Ni - 2 = 0
Or,
Ni = +2
Result:
N = -3
C = +2
Ni = +2
Answer:
Progress made in Asia and the Middle East is clear, with nations such as China, Singapore and Malaysia all demonstrating increased adaptability. Much of Africa has also made progress since 1995, along with South American nations, including Brazil and Chile.
Answer:
The first one is B and the second one is A

Answer:
Explanation:
Equation for the heterogeneous system is given as:
⇄ 
The concentrations and pressures at equilibrium are:
![[A] = 9.68*10^{-2}M](https://tex.z-dn.net/?f=%5BA%5D%20%3D%209.68%2A10%5E%7B-2%7DM)
![[C]=14.64M](https://tex.z-dn.net/?f=%5BC%5D%3D14.64M)
![[D]=10.11M](https://tex.z-dn.net/?f=%5BD%5D%3D10.11M)
If we convert both pressure into bar; we have:
1 torr = 0.001333 bar
![K=\frac{[P_E]^3}{[A]^2[P_B]^3}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BP_E%5D%5E3%7D%7B%5BA%5D%5E2%5BP_B%5D%5E3%7D)
