Lanthanum-138 has a half-life of 105 billion years. after 525 billion years, how much of a 240 g sample of this radioisotope wil
Reika [66]

The amount of the 240 g sample of the radioisotope that will remain after 525 billion years is 7.5 g

<h3>How to the number of half-lives that has elapsed</h3>
  • Half-life (t½) = 105 billion years
  • Time (t) = 525 billion years
  • Number of half-lives (n) = ?

n = t / t½

n = 525 / 105

n = 5

<h3>How to determine the amount remaining</h3>
  • Original amount (N₀) = 240 g
  • Number of half-lives (n) = 5
  • Amount remaining (N) = ?

N = N₀ / 2ⁿ

N = 240 / 2⁵

N = 240 / 32

N = 7.5 g

sp2- 3,4,5,6,7,8,9,10,11,12,14,15,17

sp- 0

Explanation:

Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties (Chemlibretexts).

Carbon atoms that are singly bonded are sp3 hybridized, carbon atoms that are doubly bonded are sp2 hybridized while carbon atoms that are triply bonded are sp hybridized.

Sp3 hybridized atoms have a tetrahedral geometry, sp2 hybridized atoms have a trigonal planar geometry while an sp hybridized atom has a linear geometry.

The hybridization state of each atom in the compound has been shown in the answer section.
