Chemistry

Answer : The heat energy required to melt 2 kg of ice was, 667.7 kJ

Explanation :

First we have to calculate the moles of ice.

\text{Moles of ice}=\frac{\text{Given mass ice}}{\text{Molar mass ice}}=\frac{2kg}{18g/mol}=\frac{2000g}{18g/mol}=111.1mol

Now we have to calculate the heat energy.

As, heat energy required to melt 1 mole of ice = 6.01 kJ

So, heat energy required to melt 111.1 mole of ice = 111.1 × 6.01 kJ

                                                                                  = 667.7 kJ

Therefore, the heat energy required to melt 2 kg of ice was, 667.7 kJ

In the redox fueling reaction, succinate + nad ↔ fumarate + nadph, the succinate molecule is undergoing which process?
GarryVolchara [31]

The answer is oxidation.

That is in the redox fueling reaction,  

succinate + NAD ↔fumarate + NADPH, the succinate molecule is undergoing oxidation.

As succinate molecule is providing electrons to NAD, so that it can be reduced from NAD to NADPH. So it is losing electrons and undergoing oxidation.

So the answer is oxidation.
