How waves affect matter at the macroscopic and particle levels.
Rus_ich [418]
In a macroscopic object, each particles wave is being absorbed and combined with the waves of the other particles to create one wave for the entire object. Since this object is able to be seen, the wave function immediately collapses.

Anytime you possess anykind of information about the world around us, some wave, somewhere function collapses.

In short, if we can see the object, then it has no wave function.

How did the Heisenberg uncertainty principle contribute to the idea that electrons occupy “clouds,” or “orbitals”?​
Step2247 [10]
How did the Heisenberg uncertainty principle contribute to the idea that electrons occupy "clouds" or "orbitals"? Because the exact position of the electron is not known,it must be assumed that the electron takes up the entire space in an orbital.

A balloon filled with helium occupies 21.0ft³ at 55.0°F. Find the temperature of the helium if the volume of the balloon decreas
harkovskaia [24]

Answer:

Assuming pressure is held constant,the question reduces to a ratio and proportion type of question where;

At constant pressure,

21.0ft³-55.0°F

11.0fy³=11.0ft³/21.0ft³×55°F

The temperature is 28.809°F≈29°F

The most common source of copper (cu) is the mineral chalcopyrite (cufes2). how many kilograms of chalcopyrite must be mined to
ser-zykov [4K]
The formula of chalcopyrite is CuFeS₂.
The molar mass of chalcopyrite   - 183.5 g/mol
The mass of Cu in 1 mol of chalcopyrite is - 63.5 g
When 183.5 g of chalcopyrite is mined, the mass of Cu obtained - 63.5 g
So if 63.g of Cu is needed mass of chalcopyrite required - 183.5 g 
Then to gain 370 g of pure Cu - mass of chalcopyrite needed -183.5/63.5 x 370
therefore mass of chalcopyrite to be mined - 1069.21 g

Lerok [7]

For the following alkyne structure, the hybridization of each carbon in the molecule is C1 = Sp3, C2=Sp3, C3=Sp, C4=Sp, C5= Sp3

Bond angle=

1)C1-C2-C3= 109 degree 28

2)C2-C3-C4=180 degree

3)C3-C4-C5= 180 degrees

Effective molecular charge order= S> Si> AI> Mg

What is hybridization?

In chemistry, orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (having different energies, shapes, etc. than the component atomic orbitals) suitable for electron pairing. Yes, they form chemical bonds through valence bond formation.

Hybridization is defined as the concept of mixing two atomic orbitals to create a new type of hybrid orbital. This mixing usually results in the formation of hybrid orbitals with very different energies, shapes, etc.
