Nitric acid.
The reaction is:N2H4------------------------------(N2H5)+ + (OH)-
The product is water vapor.
The balanced equation for the reaction between dinitrogen tetroxide and water is: N2O4 + H2O -> 2HNO3
The product formed when benzoic acid reacts with ethanol is ethyl benzoate, along with water. This reaction is an esterification process, where the -OH group of the benzoic acid reacts with the -OH group of ethanol to form the ester and water as a byproduct.
This compound is formally called dinitrogen trioxide. It is produced when the anhydride of nitrous acid is mixed with water.
The products are potassium chloride and water.
Carbon dioxide is the other product.
Sodium ion exist in water as the product of a dissociation; sodium (metal) react violently with water
Water vapor is less dense than dinitrogen under the same conditions of temperature and pressure because the molecular weight of water vapor is lower than that of dinitrogen. This difference in molecular weight means that water vapor has fewer molecules present in a given volume compared to dinitrogen, resulting in lower density.
Sulfur trioxide reacts with water to form sulfuric acid (H2SO4). This reaction is highly exothermic and produces heat.
The chemical reaction is:Na2Cr2O7 + 2 NaOH = 2 Na2CrO4 + H2O
HCl, and you get water as another product.
