Why does the temperature rise when hydrochloric acid is mixed with sodium hydroxide?

This is an EXOTHERMIC reaction. If you hold the reaction vessel it will feel warm.
For all reactions there is an energy change. In this case when the sodium ions and the hydrogen ions associate with water molecules, there is a 'bond' forming. Bond forming releases energy, hence the heat/warmth.
Conversely, when you want to break a bond e.g. calcium carbonate to form calcium oxide and carbon dioxide, you heat the calcium carbonate, you a driving in heat to break the bonds. It is Endothermic.

What is the balanced reaction when hydrochloric acid is mixed with sodium hydroxide?
NaOH + HCl --> NaCl + H2O
When dilute hydrochloric acid gets mixed with sodium hydroxide what will form?
It will form salt sodium chloride and water (Nacl + H20)
When hydrochloric acid is mixed with the base sodium hydroxide the solution becomes very hot. Which conclusion explains why the heat was released?
It is an exothermic reaction.
What happens when copper chloride is mixed with sodium hydroxide?
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.

When hydrochloric acid and potassium hydroxide are mixed what gas is given off?
I have no idea. The products of that reaction are water (not a gas at room temperature) and potassium chloride (not a gas at room temperature).
What will happen when caustic soda gets mixed with sodium hydroxide?
Caustic soda and Sodium hydroxide are the same chemical !
When citric acid react with sodium hydroxide what is the product?
Citric acid and sodium hydroxide combined makes sodium citrate.
What is the salt formed when sodium hydroxide and hydrochloric acid are mixed?
Sodium chloride. Here is the reaction equation NaOH(aq) + HCl(aq) = H2O(l) + NaCl(aq)[sodium chloride]. NB Sodium chloride is common table salt that you put on food.
What is the name of the salt which forms when hydrochloric acid is mixed with sodium carbonate?
Sodium chloride
What term is used to describe sodium hydroxide?
There is not a term used to described sodium hydroxide. If it is mixed with another element it would be referred to as hydrolysis.
What happens when sodium chloride is mixed with hydrochloric acid?
Nothing
