The temperature that must be to freeze the solution would be -21.1 ° C.
<h3>How to calculate the freezing temperature of this solution?</h3>
To calculate the freezing temperature we must take into account the following information.
- Solution with a salt concentration of 10% is frozen at -6°C
- Solution with a salt concentration of 20% is frozen at -16°C
- Solution with a higher concentration is frozen at -21.1°C
According to the above, it can be inferred that the puddle has a 50% concentration of salt because they had 12 kg of water and 6 kg of salt.
So the lowest freezing temperature would be 21.1°C because the puddle is 50% concentrated.
Note: This question is incomplete because there is some missing information. Here is the missing information:
- A 10% salt solution freezes at about 20°F (-6°C), and a 20% solution freezes at 2°F (-16°C).
- The lowest freezing point obtainable for salt solutions is −21.1 °C

Static. Is the bond if u need 2 know
Answer:
Succinate oxidation to fumarate The following reactions transform succinate to regenerate oxalacetate. The first of these reactions is carried out by an oxidation catalyzed by succinate dehydrogenase. The hydrogen acceptor is FAD, since the free energy change is insufficient to allow NAD to interact. The final product is fumarate.
Explanation:
The condensation reaction of GDP + Pi and the hydrolysis of Succinyl-CoA involve the H2O necessary to balance the equation.
