The amino acid chain will be; Lysine-Arginine-Cysteine
Amino acids are the building block of proteins, many amino acid molecules make up polypeptide chains which form proteins. Each amino acid is coded by a specific codon during the process of translation. A codon consists of three nucleotide bases. In this case AAG codes for amino acid Lysine, while AGA codes for Arginine and UGU codes for amino acid Cysteine.
Answer is: pOH = 3,29.
Kb(NH₃) = 1,5·10⁻⁶.
c(NH₃) = 0,175M.
pOH = ?
Chemical reaction: NH₃ + H₂O ⇄ NH₄⁺ + OH⁻.
Kb = c(NH₄⁺) · c(OH⁻) ÷ c(NH₃).
c(NH₄⁺) = c(OH⁻) = x.
x² = Kb · c(NH₃)
x² = 1,5·10⁻⁶ · 0,175 = 2,625 ·10⁻⁷.
x = c(OH⁻) = √2,625 ·10⁻⁷ = 5,12 · 10⁻⁴.
pOH = -log(c(OH⁻)) = 3,29.
Hydrogen and oxygen react under a specific set of conditions to produce water according to the equation: 2H2(g)+O2(g) -> 2H2O(g)
I think, but i hope this helps :)
The balanced chemical reaction is expressed as:
3HCl + Al(OH)3 = AlCl3 + 3H2O
We are given the amount of aluminum hydroxide to be used up in the reaction. This value will be the starting point for the calculations. We calculate as follows:
1.55 g Al(OH)3 ( 1 mol Al(OH)3 / 78 g Al(OH)3 )( 3 mol HCl / 1 mol Al(OH)3 ) = 0.06 mol HCl
Volume = 0.06 mol HCl / 0.120 mol HCl/ L solution = 0.50 L solution
