After decades of lithium-ion batteries dominating the market, a new option has emerged: batteries made with sodium ions. Scientists have been researching alternatives to lithium for years. Much of ...
例如:Na2O2+Na2S+2H2O=4 NaOH+S↓ 同理,如果反应物都是酸性物质,若不发生复分解反应,仅发生氧化还原反应。只需要依据氧化还原反应的规律就可以完成方程式的书写。 在高中涉及的反应中,难度较大的是以下两类反应:①既有酸性又有氧化性的物质与既有 ...
