One assumption of the ideal gas law is that the atoms or molecules themselves occupy a negligible volume. Verify that this assum

ption is reasonable by considering gaseous xenon (Xe). Xenon has an atomic radius of 2.0 x 10-10 m. For STP conditions, calculate the percentage of the total volume occupied by the atoms. Express your answer as a percentage with no units.

3 0

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 %

Mendeleev put elements in groups while creating the periodic table. What important role do groups play in the structure of the p
NikAS [45]

Answer:

Groups show similar chemical properties about the elements

Explanation:

The periodic table is divided into groups and periods. Groups are vertical while periods are horizontal.

All elements in the same group possess the same number of outermost shell electrons. This number of outermost shell electrons controls the reactivity of the elements in the group.

Hence, groups show similar chemical properties of the elements in them, Groups separate elements into families which assist in the speedy study of elements.

SCORPION-xisa [38]
The amount of chemical energy is equal to the amount of heat and light energy.

This is due to the principle of conservation of energy, which states that the total energy of a system remains constant.

If this decay has a half life of 2.60 years, what mass of 72.5 g of sodium 22 will remain after 15.6 years
Vlad1618 [11]

Sodium-22 remain : 1.13 g

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually, radioactive elements have an unstable atomic nucleus.  

General formulas used in decay:  

\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}

T = duration of decay  

t 1/2 = half-life  

N₀ = the number of initial radioactive atoms  

Nt = the number of radioactive atoms left after decaying during T time  

half-life = t 1/2=2.6 years

T=15.6 years

No=72.5 g

\tt Nt=72.5.\dfrac{1}{2}^{15.6/2.6}\\\\Nt=72.5.\dfrac{1}{2}^6\\\\Nt=1.13~g
