Answer:
The correct option is d.
Explanation:
The reaction in the question is that for the formation of ammonia. The arrow in the reaction should be a reversible arrow. Because of the negative ΔH value, the forward reaction is exothermic while the reverse reaction is endothermic.
An increase in temperature of a system at equilibrium favors the endothermic reaction, hence the reverse reaction (the reactants) is favored. And when the reverse reaction is favored, more reactants are produced. Hence, product formation (at equilibrium) is not favored as the temperature is raised.
Answer:
0.92 atm
Explanation:
Assuming this is the ideal gas law, PV = nRT. Plug in the values for each.
P = unknown
V = 6.0 L
n = 0.190 moles
R = 0.0821 (there are other rates of constant, such as 8.31, 62.4, but match it up to the correct units! 8.31 will answer in units of kPa and 62.4 will answer in units of mmHg, and lastly 0.0821 answers in atm.)
T = 354.0 K
Set up your equation.
P(6) = 0.190(0.0821)(354)
6p = 5.522046
Divide.
p = 0.920341...
Answer: 0.92 atm
Hope this is right!
The answer is temperature!
Answer:
3 "digits" are required to code for the 20 different amino acids.
This means that in order to code for one amino acid, you require a group of 3 nucleotides, which is called a 'codon'
Explanation:
If each nucleotide determined one amino acid, we could only code for four different amino acids, since DNA contains only four kinds of nucleotides.
If an amino acid were to be coded by a group of two nucleotides, the total number of diniclueotides we could get would be 4^2 = 16. This means that we could only code for 16 amino acids, which is an inferior amount than the number of amino acids required for protein synthesis (20).
If an amino acid were to be coded by a group of three nucleotides, the total number of trinucleotides we could get would be 4^3 = 64. This means that the total amount of triplets we could get is 64, which is more than enough to be able to code for the 20 different amino acids.
