Answer:
Percent yield = 65.2 %
Explanation:
The reaction determines this:
2 moles of Al react to 3 moles of chlorine gas in order to produce 2 mol of aluminum chloride.
We determine the moles of chlorine:
52 g . 1mol /70.9g = 0.733 moles of Cl₂
3 moles of gas can produce 2 moles of salt
Then, our 0.733 moles may produce (0.733 . 2) / 3 = 0.489 moles of AlCl₃
We convert moles to mass to predict the 100 % yield
0.489 mol . 133.3 g /mol = 65.19 g
Percent yield = (Yield produced / 100 % yield) . 100
Percent yield = (42.5 g / 65.19g) . 100 = 65.2 %
Answer:
mass = moles x molar mass
m= 3.7 x (23x2+16)
m= 3.7x62
m= 229.4g
Answer:
Explanation:
H ₂ S O ₄ + 2 N a O H ⟶ 2 H ₂ O + N a ₂ S O ₄
29.09 mL of 0.639 M N a O H is mixed with 213.8 mL of H ₂ S O ₄
Let the concentration of H ₂ S O ₄ be S₂ .
In terms of normal or equivalent solution is will be 2 N solution
From the formula S₁ V₁ = S₂ V₂
= 29.09 x .639 = 213.8 x S₂
S₂ = .087 N solution
In terms of molar solution it will be .087 / 2 M
= .0435 M
The anticodons corresponding to the codons on the mRNA (from part A) is 5' CGA - AAA - GUU 3'.
<h3>What are anticodons?</h3>
Anticodons are nucleotide sequences on tRNA molecules that are complementary to the codons found on mRNA molecules.
The anticodons on tRNA molecules determine the amino acid that is carried by the tRNA.
Just like codons, anticodons occur in triplets of nucleotide sequences.
Considering the codons on the mRNA molecule:
3’ GCT | TTT | CAA | AAA ’5
The complementary anticodon will be:
5' CGA - AAA - GUU 3'
