Which of the following is a reasonable ground-state electron configuration?A) 1s21p62d2B) 1s22s42p6C) 1s22s22p5D) 1s22s22d6
Semenov [28]

Answer:

  • <u><em>Option C) 1s² 2s² 2p⁵</em></u>

Explanation:

<em>Ground-state</em> is the configuration of the electrons when every electron of the atom occupies the lowest possible energy level.

The rank of energy of the orbitals may be remembered using Aufbau rules, and it is:

1s² < 2s² < 2p⁶ < 3s² < 3p⁶ < 4s² < 3d¹⁰ < 4p⁶ < 5s² < 4d¹⁰ < 5p⁶ < 6s² < 4f¹⁴ < 5d¹⁰ < 6p⁶ < 7s² < 5f¹⁴ < 6d¹⁰ < 7p⁶

Then, to find whether an electron configuration corresponds to a ground-state one, you must check that the previous order is preserved.

<u>Option A). 1s² 1p⁶ 2d²</u>

The orbital 1p does not exist. So this one is discarded.

<u>Option B) 1s² 2s⁴ 2p⁶</u>

The maximum number of electrons in an s orbital is 2, so 2s⁴ is impossible, and this option is discarded.

<u>Option C) 1s² 2s² 2p⁵</u>

This is correct because the orbitals are filled in the correct increasing energy order, without jumping any one.

<u>Option D) 1s² 2s² 2d⁶</u>

Orbital 2d does not exist, so this option is also discarded.

How many covalent bonds does oxygen form if each of its unpaired electrons participate in one bond?
ICE Princess25 [194]
The oxygen atom has 4 valence electrons. Valence electrons are the electrons found in the outermost shell of an atom. These are the electrons that participate in chemical reactions during bonding. Since 4 electrons make up 2 pairs, an oxygen atom is capable of making <em>2 covalent bonds</em>.

Mannitol salt agar is defined as both a selective and a differential agar since it selects against non-halophiles and allows the
viktelen [127]

Answer: The above statement is true

Explanation:

Mannitol salt agar is a medium which contain high concentration of salt,about 7.5%-10%. It is commonly used as a selective and differential growth medium.Because of its high concentration of salt,it inhibits growth if non halophiles(as they only grow best in media containing less tha 0.2M salts). If the bacteria can ferment mannitol,an acidic byproduct is formed which turns phenol red agar into yellow.So only those bacteria grow well which can ferment mannitol.

H2O+O2=H202, how would I balance this equation?
Sergio [31]

Answer:

2H2O2→2H2O+O2

Explanation:

This reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

Add 2 molecules of hydrogen peroxide and 2 molecules of water. Since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

2H2O2→2H2O+O2
