No, the equilibrium constant (Ksp) cannot be negative. It is always a positive value or zero, representing the extent of solubility of a salt in a solution.
When heat flows into a system, its value is positive because the system is gaining heat energy. When heat flows out of a system, its value is negative because the system is losing heat energy.
Yes, percent change can be negative. A negative percent change indicates a decrease in quantity or value from the original amount. It is calculated by comparing the final value to the initial value.
The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.
No, exergy is a measure of a system's potential to do work and cannot be negative. If the exergy value calculated for a system results in a negative number, it is likely due to errors in the calculations or assumptions made.
