Assuming that the reaction proceeds, the reaction would be a double displacement reaction.
BaCl2 + 2NH4CH3COO -> Ba(CH3COO)2 + 2NH4Cl
If the reaction occurs in an aqueous solution, the products are soluble in water, so the reaction is probably not that interesting to look at.
Answer:
1.10 × 10⁻¹² m
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
ν = 2.73 × 10²⁰ Hz
<u>Step 2: Find wavelength</u>
3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)
λ = 1.0989 × 10⁻¹² m
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m
405 PHz
I might be wrong because that might be for 0.74 nm. We will see with out people answers
