Tju [1.3M]

Molecular orbital energy is the energy associated with each electron in an atom or molecule.

It is expressed in electron volts (eV) and is determined by the electron's position in the atom or molecule. The molecular orbital energy diagram and fill-in the electrons are given here in each case, the number of valence electrons in the species is determined first; this is followed by the valence molecular orbital diagram for each species.

σ2s* ← 0 e-

σ2s ← 2 e-

σ2p* ← 0 e-

σ2p ← 0 e-

π2p* ← 0 e-

What is an alloy? A. A substitution of one metal for another metal B. A metal with a changed oxidation state C. A combination of

raketka [301]

The correct answer is the combination of a metal with another element.

An alloy is a combination of two or more metallic elements to make a stronger material. For instance, there are bronze alloys, brass alloys, and coin alloys.

We can confirm that an alloy is a combination of one metal with another metal because stainless steel is made of an iron and chromium alloy (iron is a metal; chromium is also a metal). Therefore, we can confirm that option C is the best choice.

Why the telescopes that detected no optical radiation are useful for studying objects in space

Afina-wow [57]

I would say that if they would use the regular ones, they would not be able to see very far. as well with that i would add that they need special lenses to see far.
hope that this helps you! =)

An aqueous solution was created by placing 0.018 g of NaCl into a 50 mL volumetric flask and diluting to volume with deionized w

Burka [1]

Answer:

Molarity: 6.2x10⁻³M NaCl

Molality: 6.2x10⁻³m NaCl

Mole Fraction: 1.1x10⁻⁴

Mass% NaCl: 0.036% (m/m NaCl)

Explanation:

<em>Molarity -Moles NaCl / L-</em>

<em>Moles NaCl -Molar mass: 58.44g/mol-</em>

0.018g * (1mol/58.44g) = <em>0.000308 moles NaCl</em>

<em>Liters water:</em>

50mL * (1L/1000mL) = <em>0.050L</em>

M = 0.000308 moles NaCl / 0.050L

<em>Molality -Moles NaCl / kg water-</em>

<em>Moles NaCl = 0.000308 moles NaCl</em>

<em>kg water = 50mL * (1g/mL) * (1kg/1000g) = 0.050kg</em>

m = 0.000308 moles NaCl / 0.050kg

<em>Mole Fraction -Moles NaCl / Moles water+ Moles NaCl-</em>

<em>Moles water = 50g * (1mol/18.01g) = 2.776 moles</em>

Moles fraction = 0.000308 moles NaCl / 0.000308 moles NaCl + 2.776moles water

<h3>Mole fraction = 1.1x10⁻⁴</h3><h3 />

<em>Mass Percent -Mass NaCl / Mass NaCl+Mass Water * 100</em>

0.018g / 50g+0.018g * 100
