Which process is an example of an exothermic reaction?
Hf, reactants > Hf, products
Why is that when NaOH H2SO4 and phenophtalein in conical flask becomes hot after shaking during titration?
The reaction between NaOH and H2SO4 is highly exothermic, meaning it releases heat. When the solutions are mixed in the conical flask and shaken during titration, this reaction occurs and produces a significant amount of heat. Additionally, the presence of phenolphthalein might contribute to the sensation of heat as it can change color when exposed to heat or pH changes, indicating the progress of the reaction.
What compound is the process of dissolving in water exothermic?
The process of dissolving ammonium nitrate (NH4NO3) in water is considered endothermic, meaning it absorbs heat from the surroundings. However, an example of an exothermic dissolution process is the dissolving of sodium hydroxide (NaOH) in water. When NaOH dissolves, it releases heat, resulting in an increase in temperature of the solution.
Why is the reaction between sodium and water a chemical reaction?
The reaction is:2 Na + 2 H2O = 2 NaOH + H2
What are the reactants in the reaction HCl plus NaOH NaCl plus H2O.?
In the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH), the reactants are HCl and NaOH. When these two substances react, they undergo a neutralization reaction to produce sodium chloride (NaCl) and water (H2O).
What chemical reactions are exothermic?
Any chemical reaction that produces energy is exothermic. A erection that requires energy is endothermic. For instance, NaCl + H20 -> HCl + NaOH is endothermic. Run the equation the opposite direction, HCl _+ NaOH -> NaCl + H20 and it's an exothermic reaction.
What is the temperature of naoh plus H2O exothermic reaction?
36oC
What is the balance equation for the reaction sodium hydroxide with water in an exothemic reaction?
When solid sodium hydroxide dissolves in water, the water heats up, demonstrating that the process of dissolving is exothermic for NaOH. (Very exothermic, in fact, releasing about 45kJ of heat per mole dissolved -- enough to heat a liter of H2O by 10C!) Since heat can be thought of as a product in an exothermic reaction, the equation is: NaOH (s) ---> Na+ (aq) + OH_ (aq) + 45kJ
If lye NaOH is placed in water the solution gets very hot. what kind of reaction is this?
This is an exothermic reaction, which releases heat energy as the lye (NaOH) dissolves in water. This heat is generated due to the interaction between the ions in the NaOH and the water molecules.
What the distinguish between exothermic and endothermic?
Endothermic reactions are reactions that create bonds between atoms, which means they require energy, so they take heat energy from its surroundings to create the bonds (meaning the reaction produces "cold"), and exothermic reactions are ones which break bonds between atoms, giving off energy and thus heat.
Why is the reaction between HCl and NaOH exothermic?
The reaction between HCl and NaOH is exothermic because it releases energy in the form of heat. This is due to the formation of water when the acid (HCl) and base (NaOH) neutralize each other. The breaking of bonds in the reactants and the formation of new bonds in the products results in a net release of energy.
Is sodium hydrogencarbonate and citric acid an exothermic or endothermic reaction?
The reaction between sodium hydrogencarbonate (baking soda) and citric acid is an endothermic reaction. This is because energy is absorbed from the surroundings in the form of heat during the reaction, causing the surroundings to cool down. This reaction is commonly used in baking to produce carbon dioxide gas, which helps baked goods rise.

Is heat generated with NaOH plus HNO3 reaction?
Yes, heat is typically generated when NaOH reacts with HNO3 due to the exothermic nature of the reaction. This reaction produces sodium nitrate (NaNO3) and water (H2O) as products along with heat.
What happen when sodium peroxide dissolve in water?
na2o2+h2o gives h2o2 + naoh af And the reaction is highly exothermic.
