Given things: Ca, HCl, H2O, CaO, Cu, NaOH Which of the things will interact with each other? Write the reaction equations and name the resulting things

1) Сa + 2HCl → CaCl2 + H2 (calcium chloride, hydrogen) – since acids react with metals that stand up to hydrogen in the row of metal activity.

2) Ca + 2H2O → Ca (OH) 2 + H2 (calcium hydroxide, hydrogen) – since alkali and alkaline earth metals react with water to form alkalis.

3) 2HCl + CaO → CaCl2 + H2O (calcium chloride, water) – since acids react with basic oxides.

4) HCl + NaOH → NaCl + H2O (sodium chloride, water) – since acids react with bases (neutralization reaction).

5) H2O + CaO → Ca (OH) 2 (calcium hydroxide) – since oxides of alkali and alkaline earth metals react with water to form alkalis.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
