Answer:
Explanation:
Utilizing Rydber's equation:
ΔE = Z²Rh ( 1/n₁² - 1/n₂²) and substituting the values given ( using the Rydbers constant value in Joules ), we have
n=1 to n= infinity
ΔE = 3² x (1/1² - 0) x 2.18 x 10⁻^18 J = 2.0 x 10⁻¹⁷ J (1/infinity is zero)
n= 3 to n= infinity
ΔE = 3² x (1/3² - 0) x 2.18 x 10⁻^18 J = 2.28 x 10^-18 J
b. The wavelength of the emitted can be obtained again by using Rydberg's equation but this time use the constant value 1.097 x 10⁷ m⁻¹ given in the problem .
1/λ = Z²Rh (1/n₁² - 1/n₂²) 10 ⁻¹ = 3² x 1.097 x 10⁷ m⁻¹ x (1/1² - 1/3²) m⁻¹
1/λ =8.8 x 10⁷ m⁻¹ ⇒ λ =1.1 x 10^-8 m
λ = 1.1 x 10^-8 m x 1 x 10⁹ nm/m = 11 nm
<u>Importance </u><u>of </u><u>Circulatory </u><u>System</u>
- This system helps in transportation of respiratory gases like O2 and CO2, nutrients, hormones, enzymes, minerals, waste products.
- It helps in storage of essential substances for future use.
- It also generates heat to the body.

The AZX symbol of a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+
<h3>What is AZX?</h3>
AZX is a symbol which stands for;
- A is the mass number
- Z is the atomic number or the number of protons
- X is the chemical symbol of the element
Note, cations are positively-charged ions having more protons than electrons due to loss of one or more electrons.
Sodium ion represented as Na+ is a cation which lost one electron. It has 13 neutrons and 11 protons.
But the mass number of an element, A is the sum of protons and neutrons of the element.
Thus, for Na+
A = 13 + 11 = 24
Z = 11
X = Na+
Therefore, the AZX symbol of a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+
