Answer:

  • Scandium: 3d
  • Yttrium: 4d
  • Lanthanum: 5d
  • Rest of rare earth elements: 4f (<em>they are part of the f-block</em>)
  • Actinide series: 5f

Explanation:

The electron subshell being filled is defined by the differential electron, which is the last electron placed in the electron configuration.

The rare earth series involves 17 elements: scandium, yttrium and 15  lanthanides. The subshell filled for these elements are:

  • Scandium: 3d
  • Yttrium: 4d
  • Lanthanum: 5d
  • Rest of rare earth elements: 4f (<em>they are part of the f-block</em>)

The actinide series includes 15 elements. The electron subshell filled for these elements is 5f (<em>they are part of the f-block</em>).

The pOH of a solution is 9.21. Calculate the hydrogen ion concentration of the solution. Be sure to report your answer to the co
11Alexandr11 [23.1K]

Answer:

[OH-] = 6.17 *10^-10

Explanation:

Step 1: Data given

pOH = 9.21

Step 2: Calculate [OH-]

pOH = -log [OH-] = 9.21

[OH-] = 10^-9.21

[OH-] = 6.17 *10^-10

Step 3: Check if it's correct

pOH + pH = 14

[H+]*[OH-] = 10^-14

pH = 14 - 9.21 = 4.79

[H+] = 10^-4.79

[H+] = 1.62 *10^-5

6.17 * 10^-10 * 1.62 * 10^-5 = 1* 10^-14

In an exorthermic reaction, what is the relation between the energy stored in the reactants to the energy stored in the products
Rashid [163]
In an exothermic reaction, heat is released. ΔH for an exothermic reaction is negative. That means that the energy stored in the reactants is higher than the energy stored in the products. 

The opposite is true for an endothermic reaction. Heat is absorbed, and <span>ΔH for an endothermic reaction is positive. This means that energy stored in the products is higher than the energy stored in the reactants.</span>
