写出下列反应的方程式。金属钠与H2O﹑Na2O2﹑NH3﹑C2H5OH﹑TiCl4﹑KCl﹑MgO﹑NaNO2的反应。
正确答案:
2Na+2H2O=2NaOH+H2↑
2Na+Na2O2=2Na2O
2Na+2NH3=2NaNH2+3H2↑
2Na+2C2H5OH=2NaOC2H5+H2↑
Na+TiCl4=4NaCl+Ti
Na+KCl=K↑+NaCl
2Na+MgO=Mg+Na2O
6Na+2NaNO2=Na2O+N2↑
2Na+Na2O2=2Na2O
2Na+2NH3=2NaNH2+3H2↑
2Na+2C2H5OH=2NaOC2H5+H2↑
Na+TiCl4=4NaCl+Ti
Na+KCl=K↑+NaCl
2Na+MgO=Mg+Na2O
6Na+2NaNO2=Na2O+N2↑
