How does the total volume of gas particles compare to the volume of the space between gas particles?

saw5 [17]

Answer:
There is more space between gas particles than the size of the particles.

Explanation:
This scenario can be understand by taking a very simple example. As we know that 1 mole of any gas at standard temperature and pressure occupy 22.4 liters of volume. Lets take Hydrogen gas and Oxygen gas, 1 mole of each gas will occupy same volume. Why it is so? Why same volume although Oxygen is 16 times more heavier? This is because the space between gas molecules is very large. Approximately the distance between gas molecules is 300 times greater than their own diameter from its neighbor molecules.

Determine the element of lowest atomic number that contains a complete d subshell in the ground state. element symbol:

allsm [11]

The component with the most low atomic number that contains a total d-subshell in the ground state is copper. Copper's electron arrangement is [Ar]3d104s1 [ A r ] 3d 10 4 s 1 .

Further Explanation:

atomic number:

The nuclear number or proton number (image Z) of a synthetic component is the quantity of protons found in the core of a particle. It is indistinguishable from the charge number of the core. The nuclear number particularly distinguishes a compound component. In an uncharged iota, the nuclear number is likewise equivalent to the quantity of electrons.

The elemenents of the intermittent table arranged by atomic mass:

atomic Mass Name substance element Number

1.0079 Hydrogen 1

4.0026 Helium 2

6.941 Lithium 3

9.0122 Beryllium 4

atomic number speak to:

The nuclear number (otherwise called the proton number) is the quantity of protons found in the core of an iota. It is customarily spoken to by the image Z. The nuclear number exceptionally distinguishes a substance component. In a particle of impartial charge nuclear number is equivalent to the quantity of electrons.

Meaning of subshell:

A subshell is a subdivision of electron shells isolated by electron orbitals. Subshells are marked s, p, d, and f in an electron design.

almond37 [142]

The question is incomplete, here is the complete question:

What volume (mL) of the partially neutralized stomach acid having concentration 2 M was neutralized by 0.1 M NaOH during the titration? (portion of 25.00 mL NaOH sample was used; this was the HCl remaining after the antacid tablet did it's job)

<u>Answer:</u> The volume of HCl neutralized is 1.25 mL

<u>Explanation:</u>

To calculate the volume of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of stomach acid which is HCl

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=1\\M_1=2M\\V_1=?mL\\n_2=1\\M_2=0.1M\\V_2=25mL$

Putting values in above equation, we get:

$1\times 2\times V_1=1\times 0.1\times 25\\\\V_1=\frac{1\times 0.1\times 25}{1\times 2}=1.25mL$

Hence, the volume of HCl neutralized is 1.25 mL

The mass of dissolved sodium carbonate is 109 g of Na₂CO₃.

<h3>What is a solution ?</h3>

A solution consists of two elements , a solute and a solvent .

A solute is dissolved into solvent to make a solution.

The concentration of a solution is measure by Molarity , Molality , mass% etc.

It is given in the question that

sodium carbonate ( Na₂CO₃) is sometimes used as a water-softening agent

a worker prepares a 0.724 m solution of Na₂CO₃ and water.

the volume of the solution is 1.421 liters.

Mass of dissolved sodium carbonate is grams =?

Concentration = 0.724 M

Volume = 1.421 liters

Molecular mass of Na₂CO₃ = 106 g

The mass of the solute needs to be determined

Molarity = moles / volume\

moles = Molarity x volume

Substituting the values

moles = 0.724 x 1.421

moles = 1.029

1 mol of Na₂CO₃ means 106 gm of Na₂CO₃

Then 1.029 moles will mean 1.029 * 106

109.07 gm

Therefore , the mass of dissolved sodium carbonate is 109 grams.
