<u>Given:</u>
The number of particles = 3.131 * 10²⁴
<u>To determine:</u>
The number of moles corresponding to the given particles
<u>Explanation:</u>
1 mole corresponds to Avogadro's number of particles = 6.023 * 10²³ particles
Therefore, the given particles would correspond to:
3.131* 10²⁴ particles * 1 moles/6.023 * 10²³ particles = 5.199 moles
Ans: A) 5.199 moles are contained in 3.131* 10²⁴ particles
Answer:
The period number tells which is the highest energy level occupied by the electrons.
Explanation:
- The period number (denoted by n) is the outer energy level that is occupied by electrons in an atom.
- The period number that an element is in, is the number of energy levels that the element has.
- When we move across a period from left to right in a periodic table the number of electrons in atoms increases within the same orbit.
From the graph shown, Y2 = N2, X2 = O2, Z2 = H2.
When atoms of elements are at a large distance from each other, the potential energy of the system is high. However, as the atoms approach each other, the potential energy of the system decreases steadily. The closer the atoms come to each other, the lower the potential energy. This implies that potential energy is proportional to bond length.
Since N2 has a shorter bond length and higher energy, Y2 must be N2. The bond energy of hydrogen is small hence H2 must be X2. The bond energy of a double bond is intermediate between that of a single and triple bond hence Z2 must be O2.
