99 закончи уравнения реакций: naoh+h2so4 naoh+co2 naoh+cuso4 naoh+cl2 naoh+p2o5 составь молекулярные и ионные (там, где возможно) уравнения реакций

Answer 1

$\begin{array}{l} 2NaOH + H_{2}SO_{4} = Na_{2}SO_{4} + 2H_{2}O \\ 2Na^{+} + 2OH^{-} + 2H^{+} + SO_{4}^{2-} = 2Na^{+} + SO_{4}^{2-} + H_{2}O \\ OH^{-} + H^{+} = H_{2}O \end{array}$

$\begin{array}{l} 2NaOH + CO_{2} = Na_{2}CO_{3} + H_{2}O \\ 2Na^{+} + 2OH^{-} + CO_{2} = 2Na^{+} + CO_{3}^{2-} + H_{2}O \\ 2OH^{-} + CO_{2} = CO_{3}^{2-} + H_{2}O \end{array}$

$\begin{array}{l} 2NaOH + CuSO_{4} = Na_{2}SO_{4} + Cu(OH)_{2} \\ 2Na^{+} + 2OH^{-} + Cu^{2+} + SO_{4}^{2-} = 2Na^{+} + SO_{4}^{2-} + Cu(OH)_{2} \\ 2OH^{-} + Cu^{2+} = Cu(OH)_{2} \end{array}$

$\begin{array}{l} 2NaOH + Cl_{2} = NaCl + NaClO + H_{2}O \\ 2Na^{+} + 2OH^{-} + Cl_{2} = Na^{+} + Cl^{-} + Na^{+} + ClO^{-} + H_{2}O \\ 2OH^{-} + Cl_{2} = Cl^{-} + ClO^{-} + H_{2}O \end{array}$

$\begin{array}{l} 6NaOH + P_{2}O_{5} = 2Na_{3}PO_{4} + 3H_{2}O \\ 6Na^{+} + 6OH^{-} + P_{2}O_{5} = 6Na^{+} + 2PO_{4}^{3-} + 3H_{2}O \\ 6OH^{-} + P_{2}O_{5} = 2PO_{4}^{3-} + 3H_{2}O \end{array}$
