[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]
Here we go ~
There are 4 carbon atoms in the chain, so it's prefix should be " But " and there are only sigma bonds, therefore the primary suffix will be " ane ", and the functional group attached to the end is " OH " denoting alcohol group, so the secondary suffix will be " ol "
Hence, the name of the compound will be ~

Answer:
the nucleoid
Explanation:
Compare the properties of the four state of matter in terms of particle arrangement, particle motion, shape,
size, and compressibility
Solid-
shape-retains a fixed volume and shapenot easily compressibledoes not flow easily , Particles in a solid are tightly packed, usually in a regular pattern. Particles in a solid vibrate (jiggle) but generally do not move from place to place.liquid-
shape-assumes the shape of the part of the container which it occupiesnot easily compressibleParticles in a liquid are close together with no regular arrangement. Particles in a liquid vibrate, move about, and slide past each other.Gas-
shape-assumes the shape and volume of its containercompressibleParticles in a gas are well separated with no regular arrangement. Particles in a gas vibrate and move freely at high speeds.Plasma-
shape-variable volume and shapePlasma is slightly different from the other phases of matter, in that the high temperatures cause the atoms/particles to break apart into electrons and nuclei. This mixture of electrons and nuclei act similarly to gas particles, moving freely and have no distinct arrangement.Calculate the volume of 100. grams of oxygen gas (O₂) at 25.0°C and a pressure of 1.25 atm.
Ideal gas law states
PV = n(RT)V is volume (L), P is pressure (atm), R is universal gas constant: 0.0821 L·atm/mol· K, n is number of moles, T is temperature in Kelvin
Here given:
[tex]\blacksquare[/tex] mass of O₂ : 100 gram
[tex]\blacksquare[/tex] moles: mass/molar mass = 100/32 = 3.125 moles
[tex]\blacksquare[/tex] 25.0 °C = (25+273.15) = 298.15 K
[tex]\blacksquare[/tex] pressure: 1.25 atm
Volume:
[tex]\boxed{\sf V=\dfrac{nRT}{P}}[/tex]
[tex]\Rightarrow \sf V=\dfrac{(3.125 \ x \ 0.0821 \ x \ 298.15 )}{1.25}[/tex]
[tex]\Rightarrow \sf V=61.195 \ L[/tex]
[tex]\Rightarrow \sf V=61.2 \ L \ \ \ (rounded \ to \ nearest \ tenth)[/tex]
Additional Explanation:
Volume can be counted in multiple units.In Liters: 61.2 Liters
In cubic meter: 0.061163 m³
In cubic centimeter: 61,163.5 cm³
Kiera and Grace are sisters. They both have blue eyes. Kiera is extremely short for her age and Grace is exceptionally tall for her age. Develop a hypothesis as to why the sisters have different statures. Justify your hypothesis in two or more complete sentences.
The hypothesis as to why the sisters have different statures occurs because from genetics we know that it is linked to the alleles so one sister is shorter than the other one was they had different alleles.
What is the genetic similarity between siblings?On average, siblings share about 50% of their DNA with each other, but some siblings share even more and some less. So while we all have approximately 50% DNA from each parent, the segments we end up getting are completely random.
Hereditary character or gene that is manifested by the absence of the opposite gene, called dominant, in this case, Kiera is extremely short for her age.

a woman put her clothes in the dryer.There is a mix of wool and cotton. After the dryer is finished wool clothes and cotton clothes are stuck together. There's no wool stuck to wool or cotton stuck to cotton.using laws of charge, explain why this is the case
Answer:
Explanation:
Explanation
There is a Plus charge on one of them (I think it is likely the wool).
There is a minus charge on the other one (So it is cotton most likely.
The point is that like charges repel (move away from each other)
Unlike charges attract. (move close to each other.)
You have a case of unlike charges attracting.

Chlorine has 7 valence electrons. With what group of elements will chlorine most readily bond?.
The elements that chlorine will most readily bond with are elements found in group one eg sodium, potassium, etc.
What is group of elements?Elements are arranged in groups in the periodic table based on their number of valance electrons.
Elements in the same group of the periodic table has similar characteristics.
Reaction between metals and nonmetalsWhen metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions.
The resulting compound is called an ionic compound.
Chlorine is the most reactive non metal and will bond easily with metals. The most reactive metals are found in group one.
Example of chlorine reaction with a group one elementCl⁻ + Na⁺ -------> NaCl
Thus, the elements that chlorine will most readily bond with are elements found in group one eg sodium, potassium, etc.

What is the density (g/L) of 5.0 moles of NH3, at 1.18 atm and 25.0°C?
Answer:
.821 g/L
Explanation:
It does not matter what the gas is, just the number of moles to calculate volume....
Ideal Gas Law :
PV = n R T R = gas constant = .082057 L-atm/(mol-K) & T in Kelvin units
(1.18)(V) = 5 * .082057 * (25 + 273.15)
V = 103.67 Liters
NOW ...to calculate density, the gas IS important...
mole weight of NH3 (from periodic table) = 17.031 gm/mole
Density = mass / volume = (5 * 17.031) / 103.67 L = .821 gm/L

Atoms are the unit of the molecule of the compound. The 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water and 3 moles of carbon dioxide in the sample.
What are atoms?Atoms are the smallest fundamental unit of the compounds that can be given by Avogadro's number.
For calculating the oxygen atoms in 5 mole water:
If 1 mole = 6.02 × 10²³
Then, 5 moles = 5 × 6.02 × 10²³
Hence, 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water.
Moles of carbon dioxide in the sample is calculated as:
If 1 mole of carbon dioxide = 6.02 × 10²³ molecules
Then moles in 1.8 x 10²⁴ molecules will be,
(1.8 x 10²⁴ molecules) ÷ (6.02 × 10²³ molecules) = 3 moles
Hence, 3 moles of carbon dioxide is present in the sample.
