Different substances can interact differently with light. So for me, I think the answer would be yes. It is possible <span>to conduct an UV/Vis spectroscopy experiment on a sample of the compound C3H3O2. Every substance is unique and has its own light interactions.</span>
Answer:
a. the solution will be weakly basic.
b. Greater than 7 because CN⁻ is a stronger base than NH₄⁺ is an acid.
Explanation:
a. The fluoride ion (F⁻) reacts with water thus:
F⁻ + H₂O → HF + OH⁻
That means that fluoride ions produce OH⁻ ions in solution doing <em>the solution will be weakly basic.</em>
b. The acidic equilibrium of NH₄⁺ is:
NH₄⁺ ⇄ NH₃ + H⁺ with a ka of 5,6x10⁻¹⁰.
The basic equilibrium of CN⁻ is:
CN⁻ + H₂O → HCN + OH⁻ with a kb of 2x10⁻⁵
That means that the production of OH⁻ from CN⁻ is higher than production of H⁺ from NH₄⁺. The CN⁻ is a stronger base than NH₄⁺ is an acid.
Thus, the pH of a salt solution of NH₄CN would be <em>Greater than 7 because CN⁻ is a stronger base than NH₄⁺ is an acid.</em>

I hope ot helps!
You would have to use the molarity of calcium hydroxide to find the moles of calcium hydroxide. Once you have moles, just convert using mole:mole ratio and find the grams of sodium hydroxide.
What’s the question lol ??
<span>A codon is a three base sequence of mRNA. It codes for a specific amino acid, and many amino acids chained together make a polypeptide, or protein.</span>
