How would a bar magnet orient itself relative to this planet's magnetic field?
Maksim231197 [3]

The magnet's north pole would point to the Earth's south pole and the magnet's south pole would point to the Earth's north pole.

<u>Explanation</u>:

  • There is a magnetic pole in the earth and the magnetic poles of the earth run using the equator and it has both the closures at the arctic pole and the Antarctic pole. The attractive positive field or the north pole is situated in the arctic zone and the south pole is situated in the Antarctic zone.  
  • The magnetic positive field or the north pole is situated in the arctic zone. Any magnet which is allowed to rotate whenever suspended on the outside of the earth will align itself with the magnetic field of the earth. That is the way the bar magnet orients itself comparative with this current planet's magnetic field.

Which shows an isomer of the molecule below?
babunello [35]
Above question is incomplete. Complete question is attached below
.......................................................................................................................

Correct Answer: Option D i.e. CH3CH2CH2CH2CH3

Reason:
Isomers are the compounds having same molecular formula, but different structural formula.

The molecular formula of the compound is C5H12

The compound present is question (i.e. 2-methyl butane) and option D (n-pentane) has same molecular formula. Hence, they are isomers.

However, compound present in option A, is the same compound provided in question. Hence, it is not an isomer. Compounds reported in option B and C has one carbon atom less and more, respectively as compared to the compound reported in question. Hence, they are also not isomers.

Write electron configurations for each of the following. the cations: Mg2+,Sn2+,K+,Al3+,Tl+,As3+
Eddi Din [679]

Answer:

  • Mg⁺² ⇒ 1s² 2s² 2p⁶
  • Sn²⁺ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰
  • K⁺ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶
  • Al³⁺ ⇒ 1s² 2s² 2p⁶
  • Ti⁺ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 4f¹⁴ 6s² 5d¹⁰
  • As⁺³ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²

Explanation:

The <em>electron configuration</em> indicates the way the electrons of an atom or ion are structured.<u> In the case of cations</u>, by knowing the electronic configuration of the atom (which is neutral), we can find out the cations' configuration by substracting <em>n</em> outermost electrons, where <em>n</em> is the charge of the cation.

Mg⁰ ⇒ [Ne] 3s² = 1s² 2s² 2p⁶ 3s². Thus

Mg⁺² ⇒ [Ne] = 1s² 2s² 2p⁶.

In a similar fashion, the answers are:

Sn²⁺ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰

K⁺ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶

Al³⁺ ⇒ 1s² 2s² 2p⁶

Ti⁺ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 4f¹⁴ 6s² 5d¹⁰

As⁺³ ⇒ 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²
