Write the general electron configuration of a transition element(b) in Period 6.

aksik [14]

The general electronic configuration of transition element is (n−1)d1−10ns1−2.

<h3>What are the transition element in period 6?</h3>

The period 6 transition metals are;

Lanthanum (La), Hafnium (Hf), Tantalum (Ta), Tungsten (W),

Rhenium (Re), Osmium (Os), Iridium (Ir), pPatinum (Pt),

Gold (Au), and Mercury (Hg).

As a rule, period 6 elements fill their 6s shells first, then their 4f, 5d, and 6p shells, in that order.

However, there are exceptions, such as gold.

Enter your answer in the provided box. Consider the reaction: N2(g) + 3H2(g) → 2NH3(g) Suppose that a particular moment during t

Mashcka [7]

Answer:

0.0253 M/s

Explanation:

From the reaction

N₂ + 3H₂ → 2NH₃

The rate of reaction can be written as

Rate = - $\frac{d[N_2]}{dt}$ = - $\frac{1}{3} \frac{d[H_2]}{dt}$ = + $\frac{1}{2} \frac{d[NH_3]}{dt}$

From the above rate equation we can conclude that the rate of reaction of N₂ is equal to one third of the rate of reaction of H₂,

So,

Rate of reaction of molecular nitrogen = $\frac{1}{3} \times 0.0759$

Upon calculation, we get rate of reaction of molecular nitrogen = 0.0253 M/s

Write the balanced reaction and solubility product expression (KSP) for dissolving silver chromate: Ag2CrO4(s). Include all char

Sonbull [250]

Answer:

2Ag⁺ (aq) + CrO₄⁻² (aq) ⇄ Ag₂CrO₄ (s) ↓

Ksp = [2s]² . [s] → 4s³

Explanation:

Ag₂CrO₄ → 2Ag⁺ + CrO₄⁻²

Chromate silver is a ionic salt that can be dissociated. When we have a mixture of both ions, we can produce the salt which is a precipitated.

2Ag⁺ (aq) + CrO₄⁻² (aq) ⇄ Ag₂CrO₄ (s) ↓ Ksp

That's the expression for the precipitation equilibrium.

To determine the solubility product expression, we work with the Ksp

Ag₂CrO₄ (s) ⇄ 2Ag⁺ (aq) + CrO₄⁻² (aq) Ksp

2 s s

Look the stoichiometry is 1:2, between the salt and the silver.

Ksp = [2s]² . [s] → 4s³
