已知NaCl中混有混有Na2CO3固体，请用简要的语言说明除去Na2CO3的方法，并写出有关反应的离子方式：______
碳酸钠与盐酸反应生成氯化钠、水和二氧化碳，要除去NaCO，可选用适量的盐酸到不再产生气体，故化学方程式为：2HCl+NaCO=2NaCl+HO+CO↑，故答案为：将混合物溶解，加入足量的盐酸，反应后将溶液加热至干；2HCl+NaCO=2NaCl+HO+CO↑．
一句描写一个老太太的话：“The nose, which was of some black co
一个黑古隆冬的鼻子，不怎么牢靠地挂在她脸上。
有个药片上写的是D/CO，这个是什么药品啊
主要有什么作用。
谢谢
是一种医用拉丁文的简写,d是指每天,co是指复方制剂,相应的还有比如h是指每小时等等.
