So for the first one It's 784.56 J (GPE)
For the second one it's KE is equal to 100 J. If you can give me a few more minutes I'll try to get the GPE
Answer:
3 NADH molecules are made from each molecule of acetyl CoA through the Krebs Cycle.
Explanation:
First, 1 NADH is produced from each carbon lost from the 6-carbon citric acid (2 NADH total). Lastly, 1 additional NADH is made from the transformation of malate into oxaloacetic acid (acceptor molecule for acetyl CoA).
There’s no other degenerate s orbital because the there can be only one s orbital for any value of n.
Answer:
40.4 kJ
Explanation:
Step 1: Given data
- Heat of sublimation of CO₂ (ΔH°sub): 32.3 kJ/mol
Step 2: Calculate the moles corresponding to 55.0 g of CO₂
The molar mass of CO₂ is 44.01 g/mol.
n = 55.0 g × 1 mol/44.01 g = 1.25 mol
Step 3: Calculate the heat (Q) required to sublimate 1.25 moles of CO₂
We will use the following expression.
Q = n × ΔH°sub
Q = 1.25 mol × 32.3 kJ/mol = 40.4 kJ
Answer:
The concentration of reactants have no effect on the rate of reaction.
Explanation:
The strength of the nucleophile doesn't affect the reaction rate of an SN1 since the nuleophile is not involved in the rate determining step. Increasing the concentration of the substrate (which is a reactant) increases the rate of reaction even though increasing the concentration of the nucleopohile has no effect on the rate of reaction. The use of polar protic solvents assist an SN1 reaction hence the solvent used can affect the rate of reaction. However, temperature affects an SN1 reaction. Increasing the temperature will increase the rate of E1 elimination reaction rather than the SN1 reaction since the both are competing reactions. Lowering the temperature favours SN1 reaction. Hence the answer.
