NEITHER HAVE GREATER ACCELERATION THEY ARE BALANCED
Answer:
The hot water remains at the top of chilled water.
Explanation:
The hot water remains at the top of chilled water because hot water has less denser as compared to chilled water. Due to higher density of chilled water, it remains at the bottom due to its greater mass while on the other hand, the hot freshwater goes upward and spreads at the top of the chilled water due to lower mass so when the hot water is added to the chilled water, hot water remains at the top.
Answer:
The false statement regarding an exothermic reaction is: <em>A.</em><em> the products have a higher enthalpy than reactants</em>
Explanation:
An exothermic reaction is a type of chemical reaction that involves the <u>release of energy from the </u><em><u>system to the surroundings</u></em>. Thus <em>increasing the temperature of the surroundings.</em>
In this reaction, the <em>enthalpy or energy of the reactants is greater than the enthalpy or energy of the products</em>.<em> </em>(
)
<u>As the enthalpy change of a reaction</u>: 
Therefore, the <em>enthalpy change for an exothermic reaction is negative</em> (
)
The boiling point of water is a physical property and is equal to 100<span>°C.
More in depth:
The reason why the boiling point is a physical property, is because it chemically doesn't change anything inside the water. It just gets to a point where it becomes so hot it starts boiling.

The temperature of the lab is assumed at 25°C while calculating Ksp. Pressure of the lab is assumed at 1 atm normal atmospheric conditions while calculating Ksp.
If we increase the temperature of the solvent, the average kinetic energies of the molecules start increases. Hence, the solvent is more able to dislodge more molecules from the surface of the solute. Thus, by increasing the temperature the solubilities of substances also increases. Temperature is directly proportional to the solubility.
As we goes on increasing the pressure of a gas, the collision between the molecules start increasing and thus the solubility goes up, as we decrease the pressure, the number of collision decreases thus solubility goes down.
Thus, with further increase in the temperature and pressure the Ksp value changes. Thus, temperature of the lab is assumed at 25°C while calculating Ksp. Pressure of the lab is must be 1 atm normal atmospheric conditions while calculating Ksp.
