Question

Химия: 1.C→CO2→H2CO3→MgCO3→ MgCl2 2.Ca→CaO→Ca(OH)2→CaCl2→CaCO3→CaO

alenafgfgf · Answer

1. C + O2(изб.) = CO2CO2 + H2O = H2CO3H2CO3 + MgCl2 = MgCO3↓ + 2HClMgCO3 + 2HCl = MgCl2 + H2O + CO2↑2. 2Ca + O2 = 2CaOCaO + H2O = Ca(OH)2Ca(OH)2 + 2HCl = CaCl2 + 2H2OCaCl2 + Na2CO3 = CaCO3↓ + 2NaClCaCO3 = CaO + CO2↑...
