What does HNO3 + NH3 create? I think it is NH4NO3 but I'm not sure.
The chemical equation for the reaction between HNO3 and NH3 is: HNO3 + NH3 → NH4NO3
HNO3 + NH3 is a neutralization reaction, where an acid (HNO3) reacts with a base (NH3) to form a salt (NH4NO3) and water.
No, there are other possible products depending on the conditions of the reaction. For example, if the reaction takes place in a solution with excess HNO3, the product can be NH4NO3·HNO3, which is a double salt. If the reaction takes place in a solution with excess NH3, the product can be (NH4)2SO4, which is a different salt.
The reaction between HNO3 and NH3 is exothermic, meaning it releases heat. This can be observed by the temperature increase of the solution during the reaction.
NH4NO3 has various industrial uses, including as a fertilizer in agriculture, as an oxidizing agent in explosives, and as a component in some rocket propellants. It is also used in the production of dyes, pharmaceuticals, and other chemicals.
