某碳酸钙和生石灰组成的样品中含碳元素的质量分数
2014年1月7日 解：设碳酸钙和生石灰组成的样品质量为100克，则所含碳元素的质量=100克×6%=6克， 因为样品中的生石灰中不含碳元素，只有碳酸钙中含有碳元素，因此可根据碳元 【题目】 某石灰厂需要测定产品生石灰中杂质（杂质只含CaCO 3 ）的质量分数．小刚进行了如图实验．请计算： （1）生成CO 2 气体的质量； （2）样品中CaCO 3 的质量分数．[题目]某石灰厂需要测定产品生石灰中杂质(杂质只含 某石灰厂需要测定产品生石灰中杂质（杂质只含caco 3 ）的质量分数。小刚进行了如图实验。请计算： （1）生成co 2 气体的质量； （2）样品中caco 3 的质量分数。某石灰厂需要测定产品生石灰中杂质(杂质只含CaCO3)的 2021年3月11日 【作出猜想】生石灰样品的成分可能是CaO、Ca (OH)2和CaCO3中的一种或几种。 【实验探究】小华同学设计如下实验进行探究。 (1)同学们经过讨论，发现通过实验②不能 2021年中考化学二轮题型突破四 实验探究题（含答案）
某碳酸钙和生石灰组成的样品中含碳元素的质量分数
某碳酸钙和生石灰组成的样品,测得其中碳元素的含量为百分之六,经充分高温煅烧后得到纯净的生石灰,则样品煅烧后新生成的生石灰占最终所得的纯净生石灰的质量分数约为 ? 解析看不懂？ 为了测定某石灰石中碳酸钙的质量分数．取石灰石样品，与足量质量分数为73%的稀盐酸在烧杯（烧杯质量为20g）中充分反应（假设石灰石样品中杂质不与稀盐酸反应也不溶于水）．有关 为了测定某石灰石中碳酸钙的质量分数．取石灰石 答：（1）2克石灰石样品中，有杂质03克； （2）石灰石样品的纯度是85%； （3）100千克这种纯度的石灰石充分煅烧后，可得到固体626千克．有一种石灰石样品其中含有的杂质是二氧化硅．某 某石灰厂需要测定产品生石灰中杂质(杂质只含CaCO3)的质量分数。 小刚进行了如图实验。 请计算:(1)生成CO2气体的质量(假设气体全部逸出,不考虑水蒸气的影响);(2)样某石灰厂需要测定产品生石灰中杂质(杂质只含CaCO3)的
