Answer:

C

Explanation:

Actually, arranged to the size of smallest to least atom radius size = C

Atomic sizes generally get smaller as you go from L to R across a row of the periodic table.

The elements that chlorine will most readily bond with are elements found in group one eg sodium, potassium, etc.

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.

When 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.

Cl⁻ + Na⁺ -------> NaCl

Thus, the elements that chlorine will most readily bond with are elements found in group one eg sodium, potassium, etc.

Answer:

the nucleoid

Explanation:

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.

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.

Answer: …

Explanation:

The Intermolecular force is a type of force which exists between particles in an Ideal gas.

Intermolecular forces are considered weaker attractions that hold molecules in gas close together. This force of attraction is present between molecules or particles.

So we can conclude that the Intermolecular force is a type of force which exists between particles in an Ideal gas.

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.

Unlike charges attract. (move close to each other.)

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

Ideal gas law states

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:

In Liters: 61.2 Liters

In cubic meter: 0.061163 m³

In cubic centimeter: 61,163.5 cm³

Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O2) and carbon dioxide (CO2). These small, fat soluble gasses and other small lipid soluble molecules can dissolve in the membrane and enter or exit the cell following their concentration gradient.

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.

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.
