Explanation:

Wind turbines generate electricity by following simple principle. Moving wind transfers energy to the to the blades of the wind mill which results in spinning of the blades. These blades are connected to internal shaft which also starts spinning. This spinning of shaft generates electricity which is further distributed to electrical substations to provide electricity to homes and businesses.

Step 1: Wind moves the blades of the turbine.

Step 2: Internal shaft spins

Step 3: Generator produces electricity

Step 4: Distribution lines carry electricity to substation

Determine the oxidation number of each element in these compounds or ions. (a) au2(seo4)3 (gold(iii) selenate) au = se = o = (b)

Stels [109]

<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

Write the chemical formula for the cation present in the aqueous solution of cuso4.

Inessa05 [86]

The ionic compounds on dissolving in aqueous solution dissociate into their respective ions that are cations and anions.

The ions present in the aqueous solution of $CuSO_4$ are $Cu^{2+}$ and $SO_{4}^{2-}$ .
