Answer:
486.17 nm
Explanation:
Using the formula 
to calculate for the wavelength of the photon emitted. where beta means a substitute for wavelength (λ) in the above equation.
Our given parameters include ;
The Rydberg constant is 1.097 × 10-2 nm-1.
an electron drops from a 4d orbital to a 2p orbital; which implies the n₂ & n₁ respectively.
Substituting them to the above equation; we can calculate for our wavelength easily;
∴
Since we've earlier said our (β) serves as a substitute for wavelength (λ)
Thus; λ = 0.002056875⁻¹
λ = 486.174 nm
λ ≅ 486.17 nm
False, as pressure increases, temperature increases, given that other factors stay the same.
Answer:
CaCl,2
the 2 goes to the bottom right side
Answer:
2H2 + O2 -------------> 2H2O
I would guess therefore 2 x 2.50 L or 5.00 L
Explanation:
Answer:
Molar mass of the gas = 15.15 g/mol
Explanation:
PV = nRT
Where,
P = pressure
n = No. of moles
R = Gas constant
T = Temperature
P = 698 torr, 1 torr = 0.00131579 atm
Temperature = 111 °C = 100 + 273.15 = 384.15 K
V = 48.7 L
R = 0.082057 L atm/mol K
Now, PV = nRT
=1.4189 mol
Molar mass = Mass/ No. of moles
= 21.5/1.4189
=15.15 g/mol
