代数方程式是初中数学的重要内容．它在化学计算中运用广泛、下面举例说明它在混合物计算中的运用。题目100于克石灰石经高温充分煅烧后，可得到生石灰60千克，求此生石灰的纯度（假设杂质不发生反应仍留在生石灰中）。1．运用一元一次方程法求解。解法1根据石灰石中含的杂质与
Algebraic equation is an important part of junior high school mathematics. It is widely used in chemical calculations. Here is an example of its use in mixture calculations. Topic 100 After calcining limestone at high temperatures, 60 kg of quick lime can be obtained, and the purity of the quicklime is assumed (assuming impurities do not react yet remain in the quicklime). 1. Use one-dimensional equation method to solve. Solution 1 based on impurities in limestone
