Chemistry
1 answer:
guapka [62]3 years ago
3 0

Explanation:

 ₁₄Si 1s²2s²2p⁶3s²3p².

Principal quantum number (n=3) have four electrons (3s²3p²).

2) ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.

Azimuthal quantum number (l=o) have seven electrons (1s²2s²3s²4s¹).

3) ₈₀Hg [Xe] 4f¹⁴5d¹⁰6s².

Principal quantum number (n=4) have thirty-two electrons (4s²4p⁶4d¹⁰4f¹⁴).

The principal quantum number is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state.

The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital.

Why is glycolysis considered by evolutionary theory to be one of the first metabolic pathways to have evolved?
Levart [38]
This is because it is found in the cytosol, does not involve oxygen, and is present in most organisms.

4. A gas has a temperature of 14 degrees C and volume of 4.5 liters. If the temperature is raised to
nlexa [21]

Answer:

v2=4.735L

Explanation:

using charles law

v1\t1 = v2\t2

v1= 4.5L

t1= 14+273= 287K       ( temperature has to be in kelvins)

t2=29+273= 302K

v2=?

by substitution;

4.5\287 = v2\302

v2=(302 x 4.5)\287

v2=4.735L

Does the half life of oxygen-18 impacts its use ( explain)
kakasveta [241]

Answer:

O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.

Select the correct answer.
Serjik [45]

Ionic bond is a chemical bond formed by the complete transfer of electrons between two atoms. The atom that loses electrons gains a positive charge (cation) and that which accepts electrons gains a negative charge (anion). Now, electronegativity is a parameter that measures the tendency of an atom to accept electrons. In the context of ionic bonding, two elements which show a significant difference in their electronegativity values form ionic bonds.

In the given examples, the difference in electronegativity is greatest between K  and Br i.e. 0.8 and 2.8 respectively with a difference of 2.0. This also makes sense since K and Br are on the extreme ends of the periodic table. Hence, potassium with a valence electron configuration of 4s1 will lose its s electron to Br (4s24p6) and form an ionic molecule K⁺Br⁻

Ans E) potassium and bromine
