Acid base reaction
It is a hydration reaction.
It is an eothermic type of reaction.
decomposition
HNO3 is a strong mineral acid. HNO3 is Nitric Acid. As an aside, when Nitric Acid and Hydrochloric Acid are mixed, it is known as 'Aqua Regia' (Royal/Regal Water). Aqua Regia will react with Gold.
single replacement
single replacment
Exothermic reaction: reaction with release of heat; for example burning of organic materials (oxydation of carbon) is a typical exothermic reaction.
fffffffffffffffffffffffffffffffffff
A balanced chemical reaction.
This reaction is a single displacement reaction, also known as a displacement reaction or a replacement reaction. In this type of reaction, one element replaces another in a compound.
Nitrate Salts. . e.g. Sodium Nitrate (NaNO3) Copper Nitrate (Cu(NO3)2) Calcium Nitrate (Ca(NO3)2). Ionically the nitrate anion is shown as ' NO3^(-) '. You can also have 'Nitrites' ( NO2^(-) _ These give the salts. NaNO2 (Sodium Nitrite) Cu(NO2)2 (Copper Nitrite) etc., Be careful, There is only ONE letter difference between NitrAte (NO3^(-) and NitrIte (NO2^(-) ) ,for a difference of ONE oxygen.
This reaction is called a "single displacement" reaction, as the sodium replaces the potassium in combination with the chlorine. *This is the high-temperature distillation reaction to produce metallic potassium, and is not a spontaneous reaction because potassium is more reactive than sodium. The corresponding single replacement reaction is K + NaCl => Na + KCl.
