na2o2+co2电荷配平
English Answer:
Sodium peroxide (Na2O2) reacts with carbon dioxide (CO2)
to form sodium carbonate (Na2CO3) and oxygen (O2). The
chemical equation for this reaction is:
2Na2O2 + 2CO2 → 2Na2CO3 + O2。
To balance the equation, we need to make sure that the
number of atoms of each element is the same on both sides
of the equation. We can do this by multiplying the
coefficients in front of each chemical formula by the
appropriate numbers.
First, we balance the sodium atoms. There are four
sodium atoms on the left side of the equation, so we need
four sodium atoms on the right side. We can do this by
multiplying the coefficient in front of Na2CO3 by 2:
2Na2O2 + 2CO2 → 4Na2CO3 + O2。
Now, we balance the oxygen atoms. There are eight
oxygen atoms on the left side of the equation, so we need
eight oxygen atoms on the right side. We can do this by
multiplying the coefficient in front of Na2CO3 by 2 and the
coefficient in front of O2 by 2:
2Na2O2 + 2CO2 → 4Na2CO3 + 2O2。
Finally, we balance the carbon atoms. There are two
carbon atoms on the left side of the equation, so we need
two carbon atoms on the right side. We can do this by
multiplying the coefficient in front of CO2 by 2:
2Na2O2 + 4CO2 → 4Na2CO3 + 2O2。
The equation is now balanced.
中文回答:
过氧化钠 (Na2O2) 与二氧化碳 (CO2) 反应生成碳酸钠
(Na2CO3) 和氧气 (O2)。此反应的化学方程式为:
2Na2O2 + 2CO2 → 2Na2CO3 + O2。
为了配平方程式,我们需要确保等式两边每个元素的原子数目
相同。我们可以通过将每个化学式前的系数乘以适当的数字来做到
这一点。
首先,我们配平钠原子。方程式左侧有四个钠原子,因此右侧
需要有四个钠原子。我们可以将 Na2CO3 前面的系数乘以 2 来做到
这一点:
2Na2O2 + 2CO2 → 4Na2CO3 + O2。
现在,我们配平氧原子。方程式左侧有八个氧原子,因此右侧
需要有八个氧原子。我们可以将 Na2CO3 前面的系数乘以 2,将 O2
前面的系数乘以 2 来做到这一点:
2Na2O2 + 2CO2 → 4Na2CO3 + 2O2。
最后,我们配平碳原子。方程式左侧有两个碳原子,因此右侧
需要有两个碳原子。我们可以将 CO2 前面的系数乘以 2 来做到这
一点:
2Na2O2 + 4CO2 → 4Na2CO3 + 2O2。
现在方程式配平了。
