Answer:
The correct answer is 0.09 percent.
Explanation:
Based on the given information, the atomic radius is 2 × 10⁻¹⁰ m. Now the atomic volume can be determined by using the formula, 4/3πr³. by putting the values we get,
v = 4/3πr³ = 4/3π(2×10⁻¹⁰ m)³
v = 3.35 × 10⁻²⁹ m³
The no. of atoms present in one mole of xenon is 6.02 × 10²³ atoms. Therefore, the total atomic volume will be,
Va = 6.02 × 10²³ × 3.35 × 10⁻²⁹
Va = 2.02 × 10⁻⁵ m³
The %age of total volume occupied can be determined by dividing the total atomic volume with the volume under STP. Under STP, the volume is 22.4 m³ or 2.24 × 10⁻² m³.
Va/V = 2.02 × 10⁻⁵ m³ / 2.24 × 10⁻² m³
= 9.02 × 10⁻⁴ or 0.09 %
Answer:
Reaction
Explanation:
A reaction that is spontaneous at low temperature
A sample of oxygen occupies 1.00 × 10⁶ mL at 575 mmHg. If the pressure is increased to 1.25 atm, the volume decreases to 6.06 × 10⁵ mL.
<h3>What does Boyle's law state?</h3>
Boyle's law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
- Step 1: Convert the initial pressure to atm.
We will use the conversion factor 1 atm = 760 mmHg.
575 mmHg × 1 atm/760 mmHg = 0.757 atm
- Step 2: Calculate the final volume of the gas
A sample of oxygen occupies 1.00 × 10⁶ mL (V₁) at 0.757 atm (P₁).
If the pressure is increased to 1.25 atm (P₂), we can calculate the new volume (V₂) using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = P₁ × V₁ / P₂
V₂ = 0.757 atm × 1.00 × 10⁶ mL / 1.25 atm = 6.06 × 10⁵ mL
A sample of oxygen occupies 1.00 × 10⁶ mL at 575 mmHg. If the pressure is increased to 1.25 atm, the volume decreases to 6.06 × 10⁵ mL.

Answer:
2 moles
Explanation:
Hi there !!
Given volume = 44.8 litres
Molar volume = 22.4 litres
No: of moles = Given volume / Molar volume
= 44.8 / 22.4 = 2 moles
The correct order of steps during the formation of an ionic bond
- Electrons are transferred
- Ions are attracted to each other
<h3>What is Ionic bonding?</h3>
This is the type of bonding which occurs as result of transfer of electrons
and is also regarded as electrovalent bonding.
When the electrons are transferred , ions form which then gets attracted
to each other and results in the formation of a compound.
