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.
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 is heat of neutralization between HCl and NaOH?
The heat of neutralization for the reaction between HCl and NaOH is -57.3 kJ/mol, indicating that 57.3 kJ of heat is released when one mole of HCl reacts with one mole of NaOH to form water and salt. This value is a standard enthalpy change that is constant under standard conditions.
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.
What happens to HCl and NaOH when reacted?
When hydrochloric acid (HCl) and sodium hydroxide (NaOH) react, they undergo a neutralization reaction to form water (H2O) and sodium chloride (NaCl), which is a salt. The reaction releases considerable heat.

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

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.

How do you determine the enthalpy change of neutralization between HCl and NaOh?
The enthalpy change of neutralization between HCl and NaOH can be determined by measuring the temperature change that occurs when the two solutions are mixed. By using calorimetry, the heat released or absorbed during the reaction can be calculated using the equation: q = mcΔT, where q is the heat exchanged, m is the mass of the solution, c is the specific heat capacity of the solution, and ΔT is the temperature change. This heat value can then be converted to enthalpy change per mole of reaction.
What is the products of sodium oxide and water?
Sodium oxide reacts with water to produce only one product: sodium hydroxide. The equation for the reaction is Na2O + H2O -> 2 NaOH.
What is the balanced chemical equation for reaction between h2so4 and naoh?
I made this reaction in a lab. you may get Na2SO3 ( sodium sulphite) and when you heat this product the final product will be Na2S2O3 (sodium tiosulphate) I hope this information can help you.
Combination of HCl and NaOH?
When hydrochloric acid (HCl) and sodium hydroxide (NaOH) are combined in water, they react to form water (H2O) and sodium chloride (NaCl), which is table salt. The reaction is exothermic, meaning it releases heat. The equation for this neutralization reaction is: HCl + NaOH -> NaCl + H2O.
What is the relationship between the heat of reaction and the heat of formation in a chemical reaction?
The heat of reaction is the difference between the heat of formation of products and reactants in a chemical reaction. It represents the amount of heat released or absorbed during the reaction. The heat of formation is the heat change when one mole of a compound is formed from its elements in their standard states. The relationship between the two is that the heat of reaction is related to the heat of formation of the substances involved in the reaction.
