Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement

2 answers:

7 0

Wood, Water, and Neon Gas, because the wood is more of a solid its particles are tightly arranged and water next because it takes the shape of the container it is in and then the neon gas because with a gas the particles are not at all arranged

I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.

Which amino acid chain will be formed by the codons shown below? aag aga ugu?

notsponge [240]

The amino acid chain will be; Lysine-Arginine-Cysteine
Amino acids are the building block of proteins, many amino acid molecules make up polypeptide chains which form proteins. Each amino acid is coded by a specific codon during the process of translation. A codon consists of three nucleotide bases. In this case AAG codes for amino acid Lysine, while AGA codes for Arginine and UGU codes for amino acid Cysteine.

Cylinders of compressed gas are typically filled to a pressure of 200 bar. For oxygen, what would be the molar volume at this pr

mars1129 [50]

Answer:

$V = 0.124 \ Liters$

$V = 0.112 \ Liters$

Explanation:

From the question we are told that

The pressure of compressed gas is $P = 200 \ bar = \frac{200}{1.013}= 197.4 \ atm$

The temperature is $T = 25^oC = 25 + 273 = 298 \ K$

Generally the perfect gas equation is mathematically represented as

$PV = nRT$

substituting 0.08206 L-atm/mol-K for R and 1 mole for n

We have that

$V = \frac{1 * 0.08206 * 298 }{ 197.4}$

$V = 0.124 \ Liters$

Generally the van der Waals equation is mathematically represented as

$nRT = [P + \frac{n^2 * a }{V^2 } ][V - nb]$

=> $1 * 0.08206 *298 = [197.4 + \frac{1^2 * 1.364}{V^2 } ][V - 1 * 3.19 * 10^{-2}]$

=> $V = 0.112 \ Liters$

Match each vocabulary word with its definition. match the items in the left column to the items in the right column. 1 . periodi

Angelina_Jolie [31]

Answer:

Explanation:

1 . periodicity

repeating nature of atomic structure

Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.

2 . shell

location of an electron

Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high

3 . non-metals

high ionization energies

Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.

4 . noble gases

least reactive family

Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.

5 . neutral

charge on a neutron

Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons

6 . repel

like charges

Like charges repel one another

7 . attract

unlike charges

Unlike charges attracts. Positve attracts negative charges.
