Answer 2

Карбонат калия
K2CO3 + 2HCl(разб. раст.) = 2KCl + CO2 + H2O
K2CO3 + Ca(OH)2(насыщен.) = CaCO3 + 2KOH

Answer 3

Reaction of Hydrochloric Acid and Calcium Hydroxide

When hydrochloric acid (HCl) and calcium hydroxide (Ca(OH)2) react, they undergo a neutralization reaction to form calcium chloride (CaCl2) and water (H2O).

The balanced chemical equation for this reaction is as follows: HCl + Ca(OH)2 → CaCl2 + H2O

Reaction of Iron with Magnesium Oxide

The reaction between iron (Fe) and magnesium oxide (MgO) does not occur under normal conditions. Iron is a less reactive metal compared to magnesium, so it does
