why are glass, quartz and plastics not used as ir sample holders?
Answer:
not used as sample holders because --> are opaque and absorb ir radiation
Explanation:
glass/quartz would absorb the IR radiation and mask the absorbtion of your sample.
IR sample holders must be made out of transparent materials. The glass, quartz, and plastics are not used as IR sample holders.
What is meant by transparent materials?Glass may travel entirely through transparent materials without any light bouncing back. Comparatively, translucent materials permit some light to pass through while also reflecting some light off their surface. All light is reflected off the surface of opaque materials.
Glass, Quartz, and plastics are not used as IR sample holders because they are opaque to IR radiation and would absorb in the IR spectrum and mask the absorption of the sample.
IR sample holders must be made out of transparent materials.
Therefore, glass, quartz, and plastics are not used as IR sample holders.

Answer:
Organic compound: 1) found naturally in or produce by living things or 2) it contains carbon
Inorganic compound: does not come form living things
Explanation:
Organic molecules associated with living organisms are also called biomolecules. Organic compounds are molecules that contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).
it was believed that chemical synthesis could occur only in living organisms and organic compounds were defined as coming from living organisms, whereas inorganic compounds come from nonliving sources.

Why does a hot air balloon float? use all the words: less dense, kinetic energy, heat, force, molecules, faster, pressure, temperature, fire, volume, increase, more, same mass, increased volume, inside the balloon
Answer:
A hot air balloon floats because, the air inside of the balloon is more dense than the air outside the balloon. The air inside the balloon is a hotter temperature and has more kinetic energy as more molecules move faster. And has to be heated enough to carry the amount of passengers and it all depends on mass. The pressure of the outside air is supporting the hot air balloon by force and the fire uses its heat to makes the balloon air increase in temperature therefore making the balloon float up because heat rises. The air inside the balloon expands and has increased volume.

What is the name of these two molecules?
Answer:polyatomic molecules
Explanation:molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.Characteristics of molecules
The division of a sample of a substance into progressively smaller parts produces no change in either its composition or its chemical properties until parts consisting of single molecules are reached. Further subdivision of the substance leads to still smaller parts that usually differ from the original substance in composition and always differ from it in chemical properties. In this latter stage of fragmentation the chemical bonds that hold the atoms together in the molecule are broken.
Are there elements with the same atomic number
Explanation:
No because each has specific atomic number and atomic mass
What takes the place of ounces in the metric system?
Answer:
Liters
Explanation:
Ounces determine weight, when you want to convert ounces to the metric system you have to convert it to liters. For example one ounce would equal 29.5735 milliliters means it is now in the metric system and will assist with finding the volume of a shape. Which means your answer is "liters."

a. Identify the steps of the scientific method?
b. 1. What was the scientific question for this experiment?
b. 2. what hypothesis did the scientist form from the question?
b. 3. What prediction could be used to test the hypothesis?
b. 4. What did the control group consist of?
b. 5. How were the data presented?
b. 6. Was the hypothesis supported or rejected by the data? Explain your answer.
b. 7. Name on possible source of error or bias in this expirement?.
b. 8. How did the fact that the article was not peer reviewed affect the scientist?
Answer:
1. The steps of the scientific method consist of seven things: Ask a question, get the research needed for a experiment, (What are you trying to find out? What materials do I need to complete the experiment? What are the procedures needed to complete the experiment?) create a hypothesis, (your educated guess on what you think the results of the experiment will be) conduct a experiment (complete multiple different trials preferably three) to test your hypothesis, make observations and record data during the experiment, draw a conclusion, (Was your hypothesis correct? Yes or no and explain why it is wrong or right) present your findings.
2. A hypothesis is a educated guess that the scientist believe will be the answer at the end of the experiment which is why they conduct a experiment in the first place to find viable data that will support their hypothesis.
3. Predictions consist of theories that will test the hypothesis (educated guess) because they're the reasoning to why you believe your guess is correct.
4. A control group consists of variables that do not go through change during a experiment, things that remain the same.
5. Data can be presented in many different ways in the form of graphs, charts, or a research paper. You find the data by completing multiple different trials in a experiment, to make sure you have valid results to write down in your data research.
6. Remember that your hypothesis is your educated guess at the beginning of the experiment, what YOU thought was going to happen during the experiment and if the data you received during the experiment supports your hypothesis.
7. Your procedures, perhaps you measured a variable wrong, perhaps you used to much, or to little of a variable, all depends on your experiment.
8. Having people review and test your data by conducting their own experiments will not only make sure that your data is valid but it insures you even more of your conclusion, making it more accepted by other scientists.

B.
A chemical change because oxygen atoms from the atmosphere bonded with the iron atoms
C.
A violation of the laws of physics because new mass has been created
Answer:
B.
Explanation:
Rust is a chemical change because you can not undo it. Rusting of iron is a chemical change because a new substance iron oxide is formed. The presence of oxygen and water or water vapour is essential for rusting.
How is a strand of DNA like a sentence?
Answer:
DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence. Together, all of the DNA "sentences" within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.
Explanation:
A strand of DNA is much like an extremely long sentence that uses only four letters. DNA actually has two strands, much like a zipper and the nucleotides are like the teeth of that zipper. This two-strand system is the key to how DNA is able to make copies of itself.

ILL GIVE YOU BRIANLIEST! PLEASE HELP: Every compound is a molecule, but every molecule is not a compound. Why is this? Give an example with your answer.
Answer:
A molecule can be made up of two atoms of the same kind:)
Explanation:
hope that helps:))
Answer:
Explanation:
A compound is a makeup of molecules.
Every organism is made up of an atom.Combined atoms can create a moleculeCombined molecules can create a compound.When you make a compound, you are combining molecules. But when you make a molecule, you are not combining compounds, you are combining atoms.
Examples:
Atoms:
[tex]\mathrm{H}[/tex] (hydrogen) and [tex]\mathrm{N}[/tex] (nitrogen)
Molecules:
[tex]\mathrm{H_2}[/tex] and [tex]\mathrm{N_2}[/tex]
Compounds:
[tex]\mathrm{H_2SO_2}[/tex] and [tex]\mathrm{NaCL}[/tex]
Take a look at the Compounds and Molecules section. The [tex]\mathrm{H_2}[/tex] in the example of a molecule is in one of the examples of the compounds, but the [tex]\mathrm{H_2SO_2}[/tex] (THE WHOLE THING) is not in the molecule. This shows how every compound is a molecule, but every molecule is not a compound.

ion
An atom that has lost or gained an electron no longer has a neutral charge. We call this negatively or positively charged atom a(n) " ion".
What are lost electrons?A positively charged atoms has lost electrons.
An Electron are easy to remove from the atom, electron has negative charge. Initially; atom is neutral that is the charge of electron is equal to the charge of the proton, when atom loose some of its electron, the net charge of electrons is less than the net charge of the Protons makes the atom positively charged.
