Crystal solid is a solid whose atoms, ions or molecules are arranged in a regular, repeating pattern.
Atoms, ions, and molecules are grouped in a highly ordered microscopic arrangement in repeated and consistent three-dimensional formations to create a crystal lattice, which can stretch in any direction.
A crystal structure is a type of solid state of matter that varies from liquid and gaseous states of matter in which the organization of atoms or molecules is random or haphazard. It is an organized arrangement of atoms, ions, or molecules in a regular repeating pattern.
Triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic crystal formations are also available. Groupings of lattices and lines identify a family of crystals.

What are the 3 Newton laws
Answer:
The laws are: (1) Every object moves in a straight line unless acted upon by a force.
(2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass.
(3) For every action, there is an equal and opposite reaction.

How many atoms are in 1.22 moles of magnesium?
Answer:
7.34684 × 10^23 atoms
Explanation:
Well, one mole is basically
6.022 × 10^23 atoms. So 1.22 moles would be
6.022 × 10^23 ⋅ 1.22 atoms.
6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms
The total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant.Given:
1.22 moles of magnesium
[tex]1 \text{ mole}= 6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}= 1.22*6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}=7.34*10^{23}\text{ atoms}[/tex]
So, the total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.

What molecular geometry would be expected for BF3 and NH3?
Answer:
Boron trifluoride would have a trigonal planar geometry.Ammonia would have a trigonal pyramidal geometry.Explanation:
There are three valence electrons in a boron atom.
In boron trifluoride, the central boron atom did not achieve an octet with eight valence electrons. Rather, that boron atom would be electron deficient with only six valence electrons.
Each of the three fluoride atoms would have shared one valence electron with that boron atom, with a total of three boron-fluorine single bonds. On the other hand, all three of the valence electrons of that boron atom would be involved in bonding. Hence, there would be no extra valence electrons to act as lone pairs on that boron atom.
Hence, the central boron atom would have three electron domains (one for each boron-fluorine bond) with none of the electron domains coming from lone pairs. By the VSEPR theory, the geometry of the molecule would be trigonal planar. All four atoms in this molecule would be in the same plane.
There are five valence electrons in a nitrogen atom.
In ammonia, the central nitrogen atom is indeed able to achieve an octet (with eight valence electrons in total.) Three of the five valence electrons of nitrogen would form a total of three hydrogen-nitrogen bonds. The other two valence electrons would form a lone pair.
Hence the central nitrogen atom would have four electron domains (one for each of the three hydrogen-nitrogen bond, and one for the lone pair.) Hence, by the VSEPR theory, the geometry of this molecule would be trigonal pyramidal.

Which additional claim can be BEST supported by the evidence from the skulls in the whale fossil record?
A.
The fossil record shows differences in the skulls of the mammals, which shows that they are from three separate species that all lived at the same time.
B.
The fossil record shows similarities in the skulls of the mammals, which shows that they must have had similar habitats and environments.
C.
The fossil record shows that some mammals evolved so that their nostrils are further at the top of their skull for better breathing while in the water.
D.
The fossil record does not give enough evidence about the mammals to determine if there is a relationship between the three skulls.
Answer:
d
Explanation:
Answer:
B
Explanation:
I think it is B because it starts out with it's nostrils so it is on the mouth causing it not to be able to breathe but over time it's nostril moved to the top of the head so they could breather better
Determine whether each change represents oxidation or reduction. 1) CH3CHO to CH3CH2OH 2) CH3OH to CH4 3) N2H4to N2 4) gain of electrons 5) NO-2 to NH3 6) NAD+ to NADH 7) CH4 to Co2 8) Ag+ to Ag
Answer:
1) oxidation
2) Reduction
3) Oxidation
4) Reduction
5) Reduction
6) Reduction
7) Oxidation
8) Reduction
Explanation:
Oxidation is said to have taken place when there is a positive change in the oxidation number while reduction is said to have taken place when there is a decrease in the oxidation number.
The change from CH3CHO to CH3CH2OH represents on oxidation reaction.
The change from CH3OH to CH4 is a reduction because the oxidation number of carbon changes from +2 to -4.
The change from N2H4to N2 is an oxidation because the oxidation number of nitrogen increases from -2 to 0.
The gain in electrons is a reduction because the gain of electron leads to a decrease in oxidation number.
The change from NO- 2 to NH3 is a reduction because the oxidation number of nitrogen changes from +4 to -3.
The change from NAD+ to NADH is a reduction since NAD+ is the oxidized form of the enzyme while NADH is the reduced form of the enzyme.
The change from CH4 to Co2 is an oxidation because the oxidation number of carbon changes from -4 to + 4.
The change from Ag+ to Ag is a reduction because it involves the gain of one electron and a consequent decrease in oxidation number.
Determine the number of moles in a 100.0g sample of water.
Answer:
5.55 moles is the answer ....
Explanation:
if 18g H2O is equal to 1 mole then 100 g H2O is how much?
100/18 which is 5.55
Answer:
5.551
Explanation:
100.0g x 1mol H20/18.015g H20 = 5.551 moles of H20
The 18.015g is from the periodic table. H = 1.008x2 = 2.016g H2
0= 15.999
15.999 + 2.016= 18.015
How do you think the artist creates sculptures that vary in color and intensity?
Answer:
Light reflected off objects. Color has three main characteristics: hue (red, green, blue, etc.), value (how light or dark it is), and intensity (how bright or dull it is). Colors can be described as warm (red, yellow) or cool (blue, gray), depending on which end of the color spectrum they fall.
Christ Crowned / Honthorst
Christ Crowned with Thorns, Gerrit van Honthorst, about 1620
Value describes the brightness of color. Artists use color value to create different moods. Dark colors in a composition suggest a lack of light, as in a night or interior scene. Dark colors can often convey a sense of mystery or foreboding.
Light colors often describe a light source or light reflected within the composition. In this painting, the dark colors suggest a night or interior scene. The artist used light colors to describe the light created by the candle flame.
Annunciation / Bouts
The Annunciation, Dieric Bouts, 1450–1455
Intensity describes the purity or strength of a color. Bright colors are undiluted and are often associated with positive energy and heightened emotions. Dull colors have been diluted by mixing with other colors and create a sedate or serious mood. In this image the artist captured both the seriousness and the joy of the scene with the dull gray stone interior and the bright red drapery.
Explanation:
Which structures join with the cell’s membrane during exocytosis?
Answer:Exocytosis is also used to integrate new proteins into the cell membrane. In this process, the new protein is formed inside the cell, and migrates to phospholipid bilayer of the vesicle. The vesicle, containing the new protein as a part of the phospholipid bilayer, fuses with the cell membrane.
Explanation:
How are the atomic number and the number of protons related to each other?
Answer:
Neutral atoms of each element contain an equal number of protons and electrons. The number of protons determines an element's atomic number and is used to distinguish one element from another. ... Together, the number of protons and the number of neutrons determine an element's mass number.

What is on the left side of the arrow 2H2+1O2 --> 2H2O
Answer:
The correct answer is - reactants.
Explanation:
In any chemical reaction, there is an arrow that distinguishes the two major components of the chemical equation by placed in between them. These two components are reactants and products.
OftenlThe reactants placed on the left side of a chemical equation and the products placed on the right side of a chemical equation. In this given case, the reactants 2H2 + 1O2 are placed on the left side of the equation.
