Answer:
6) λ = 0.84 × 10⁻⁸ m
7) λ = 0.84 × 10⁻⁶ m
Explanation:
6) Given data:
Wavelength of photon = ?
Frequency of photon = 3.56 × 10¹⁶ Hz
Solution:
Formula:
Speed of radiation = frequency × wavelength
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 3.56 × 10¹⁶ Hz × λ
λ = 3×10⁸ m/s / 3.56 × 10¹⁶ s⁻¹
λ = 0.84 × 10⁻⁸ m
7) Given data:
Wavelength of photon = ?
Frequency of photon = 6.15 × 10¹⁴ Hz
Solution:
Formula:
Speed of radiation = frequency × wavelength
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 6.15 × 10¹⁴ Hz × λ
λ = 3×10⁸ m/s / 6.15 × 10¹⁴ Hz s⁻¹
λ = 0.84 × 10⁻⁶ m
False, they have a balance between positive and negitive characters. 6 protons, 6 electrons
The molar mass<span> is the </span>mass<span> of a chemical element or a chemical compound (g) divided by the amount of substance (mol).

Balanced chemical equation: 2H2 + O2 → 2H2O
The limiting reagent will be H2
All 10.39 mol of H2 will be used up produce 10.39 mol of H20
The excess reagent will be O2 and there will be 5.78 mols left over
