CH3-COOH + CH3OH ⇒ CH3-COOCH3 + H2O
CH3-COOH + Na2CO3 ⇒ CH3-COONa + NaHCO3
Если ν H2O - это молярная масса воды, то <span>ν = 49,5 / 2,75 = 18 г/моль</span>
Ag2O + H2O → 2 Ag + H2O + O2
<span>4KOH + 2SiO2 K2SiO3 + K2Si4O5 + 2H2O</span><span>CO2 + H2O ⇄ H2CO<span>3
</span></span><span>2KOH + SO2 → K2SO3 + H2O
</span><span><span>P2O5</span> + <span>3 <span>Mg<span>(OH)</span>2</span></span> → <span>Mg3<span>(PO4)</span>2</span> + <span>3 <span>H2<span>O</span></span></span></span>
