Answer:
A
Explanation:
A site, nucleophilic attack on the carbonyl carbon, tRNA of the P site
Answer:
The answer to the question is
The temperature at which the vapor pressure will be 5.00 times higher than it was at 331 K is 353.0797 K.
Explanation:
To solve the question, we make use of the Clausius-Clapeyron equation as follows

Where P₁ = Initial pressure
P₂ = Final pressure
T₁ = Initial temperature = 331 K
T₂ = Final temperature
dvapH = ΔvapH = Heat of vaporization = 70.83 kJ / mol.
R = Universal gas constant = 8.3145. J K⁻¹ mol⁻¹
We are required to find the temperature when P₂ = 5 × P₁
Therefore we have
=
or T₂ =
= 353.0797 K
The vapor pressure be 5.00 times higher than it was at 331 K when the temperature is raised to 353.0797 K.
Answer:
[H₃O⁺] = 2.63×10⁻¹⁰ M
As pH = 9.57, the solution is basic
Explanation:
We must know this knowledge:
[OH⁻] . [H₃O⁺] = 1×10⁻¹⁴
3.8×10⁻⁵ . [H₃O⁺] = 1×10⁻¹⁴
[H₃O⁺] = 1×10⁻¹⁴ / 3.8×10⁻⁵ → 2.63×10⁻¹⁰ M
Let's determine the pH to state if the solution is acidic or basic
pH < 7 → acidic ; pH > 7 → basi
pH = - log [H₃O⁺]
pH = - log 2.63×10⁻¹⁰ → 9.57
