Write down the reaction equations in molecular forms, write down the names of the reaction products

Write down the reaction equations in molecular forms, write down the names of the reaction products, indicate the type of reactions 1 sodium hydroxide + iron (3) nitrate, 2 sodium sulfide + hydrobromic acid, 3 calcium carbonate + hydroiodic acid.

The reaction takes place between substances such as sodium hydroxide and ferric nitrate. As a result of the reaction, substances are formed: sodium nitrate salt and trivalent iron hydroxide. This reaction proceeds according to the type of exchange. Graphically, this equation of a chemical reaction can be expressed as follows:

NaOH + Fe (NO3) 3 = NaNO3 + Fe (OH) 3.

Substances such as sodium sulfide salt and hydrobromic acid enter into a chemical reaction. As a result of the reaction, sodium bromide salt and hydrogen sulfide are formed. The molecular equation of the reaction can be written as follows:

Na2S + 2 HBr = 2 NaBr + H2S

The reaction takes place between substances such as calcium carbonate and hydroiodic acid. Carbonic acid and calcium iodide salt are formed. This is an exchange reaction. The molecular equation of the reaction can be written as follows:

CaCO3 + HI = H2CO3 + CaI2.
