The negative ion in aqueous sodium hydroxide, NaOH(aq) is hydroxide ion, OH-.
<h3>What is a neutralization reaction?</h3>
A neutralization reaction is a reaction between an acid and a base to form salt and water only.
The reaction between vinegar and NaOH is a neutralization reaction which produces a salt and water only.
NaOH is composed of a positive sodium ion, Na+ and a negative hydroxide ion, OH-
Therefore, the negative ion in the NaOH(aq) used in this titration is hydroxide ion, OH-.

Answer:
Kinetic energy because it has motion, Potential energy bc there is still more distance to fall and heat energy bc there is heat from friction.
Explanation:
The attractive force that occurs between the sun and the earth is called:
Gravity
This force works to keep everything on the planet grounded.
Answer:
Option C, spontaneous or nonspontaneous depending upon the temperature of the surroundings and pressure
Explanation:
AT room temperature, the temperature is favorable for ice to melt and hence melting of ice at room temperature is spontaneous but when the temperature is below the melting point and even then the ice melts then it is called non spontaneous. In this case, the enthalpy and entropy together create a positive change in the free energy for melting.
Hence, option C is correct
