0.32gcm3 . I miss the old Kanye, straight from the 'Go Kanye

Chop up the soul Kanye, set on his goals Kanye

I hate the new Kanye, the bad mood Kanye

The always rude Kanye, spaz in the news Kanye

I miss the sweet Kanye, chop up the beats Kanye

I gotta to say at that time I'd like to meet Kanye

See I invented Kanye, it wasn't any Kanyes

And now I look and look around and there's so many Kanyes

I used to love Kanye, I used to love Kanye

I even had the pink polo, I thought I was Kanye

What if Kanye made a song about Kanye

Called "I Miss The Old Kanye, " man that would be so Kanye

That's all it was Kanye, we still love Kanye

And I love you like Kanye loves Kanye

The volume of a single platinum atom is 1.12×10-23 cm3. what is the volume of a platinum atom in microliters?

Dvinal [7]

Basically, this problem asks you to convert units of volume from cm³ to μL. Cubic centimeters is the cubic volume equivalent of milliliters or mL. According to the metric system for L, microliter is 10⁻⁶ of a liter, while milliliter is 10⁻³ of a liter. Therefore, the solution is written as

(1.12×10⁻²³ cm³)*(1 mL/1 cm³)*(10⁻³ L/ 1 mL)*(1μL/10⁻⁶ L) = 1.12×10⁻²⁰ μL

Is the following equation balanced? FeCl₃ + MgO → Fe₂O₃ + MgCl₂<br> A.<br> Yes<br> B.<br> No

VARVARA [1.3K]

Answer:

The answer is B) No.

Explanation:

The equation balanced is:

2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂

Equation balancing can be done by "trial and error" or by algebraic method.

In this way the equation is balanced on both sides having:

2 atoms of Fe, 6 of Cl, 3 of Mg and 3 of 0.

When electrons are transfered to a more electronegative molecule, what happens?

irga5000 [103]

Do u mean when electrons are transferred to the valence shell what happens to the electronegativity? The electronegativity is greater in the valence she'll because they have greater reason to pull electrons to pull towards them

Atoms have been traditionally viewed as being composed of three different types of particles: protons, neutrons, and electrons.

sattari [20]

Answer:

See explanation

Explanation:

Before the advent of the wave-particle duality theory proposed by Louis de Broglie, there was a sharp distinction between mater and waves.

However, Louis de Broglie introduced the idea that mater could display wave-like properties. Erwin Schrödinger developed this idea into what is now known as the wave mechanical model of the atom.

In this model, electrons are regarded as waves. We can only determine the probability of finding the electron within certain high probability regions within the atom called orbitals.

This idea has been the longest surviving atomic model and has greatly increased our understanding of atoms.
