Secondly, the colors. As different organism come in different areas of reflections of light, it can easily be identified with this certain color and the way that the light reflects on it. This is another form of visual appearance, and important factor in identification.
Lastly, the pattern. As located on the back, the spikes/thread-looking things sticking out plays a huge factor in finding the organism name and/or identifying it. Every organism has a different pattern, humans being a huge one, all different

A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?

A molecule contains 24.36 g of nitrogen and 62.64g of sliver
Answers
Answer:
This molecule is AgN3
Explanation:
Answer:
AgN3
Explanation:
Mass of nitrogen N is given as 24.36 g
Molar mass of nitrogen N= 14 g/mol.
amount of substance in mol of N = mass/molar mass
=24.36 g/ 14 g/mol.
=1.74 mol.
Given mass of silver= 62,64 g.
Molar mass of silver Ag=107.87 g/mol
Number of mols=62.64 g ÷ 107.87 g/mol.
=0.58 mol.
Ratio of number of mol of N and number of mols of Ag = 1.74 mol / 0.58 mol
=3:1
Hence, empirical formula is AgN₃.

How many H2O molecules are in 2 mol
Answers
Answer:
A mole of horses would be Avogadro number of horses (a lot actually !). Avogadro number is 6.023 x 10(23). A mole of H (hydrogen) atoms contains 6.023 x 10(23) H atoms. A mole of H2 molecules contains 6.023 x 10(23) H2 molecules or 2 moles of H atoms (since each molecules has 2 atoms).
Explanation:
Answer:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

PLZ FASTLEY ANSWER The images show two metamorphic rock samples.
Left: light colored rock with coarse texture. Right: red and white rock with rounded grains and coarse texture.
Which statement accurately describes these rocks?
Both rocks are non-foliated.
Neither rock has randomly arranged grains.
Both rocks formed at Earth’s surface.
Neither rock formed through extreme heat or pressure.
Answers
Answer:
a
Explanation:
From the given images, it is clear that both rocks are non-foliated rocks because they don't have distinct repetitive layers. Hence option a is correct.
What are metamorphic rocks?Metamorphic rocks are formed through intense pressure and heating from the sedimentary or igneous rocks. Sometime the change n heat or pressure make the metamorphic rocks gets foliated.
Foliation occurs when pressure forces flat or elongate minerals within a rock to align. These rocks form a platy or sheet-like structure that reflects the pressure direction. There is no platy or sheet-like structure in non-foliated metamorphic rocks.
Non-foliated rocks can be created in a variety of ways. Some rocks, like limestone, are composed of minerals that are not flat or elongate. Therefore, the given rocks are non-foliated.

Two moles of aluminum chloride are dissolved in two liters of water.
How does the vapor pressure of the water change?
It increases because aluminum and chloride ions displace water molecules, which escape into the gas phase.
It first decreases as aluminum chloride attracts the water molecules, but it then increases as dissolving completes and starts to push water molecules out.
It decreases because nonvolatile aluminum and chloride ions now occupy some of the volume of the system.
Answers
Answer: It decreases because nonvolatile aluminum and chloride ions now occupy some of the volume of the system.
Explanation:
Vapor pressure of a liquid is defined as the pressure exerted by the vapors in equilibrium with the liquid/solution at a particular temperature.
So, when a non-volatile solute is added to a solvent then its molecules align at the surface of liquid. As a result, less number of solvent molecules will escape from the solution. Thus, there will be decrease in vapors and thus the vapor pressure decrease.
The relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
A decrease in temperature decreases

Answers
Answer:
The reaction rate decreases with a decrease in temperature. ... Molecules joined by stronger bonds will have lower reaction rates than will molecules joined by weaker bonds, due to the increased amount of energy required to break the stronger bonds.
