Question

the treatment of water involves several steps such as screening, word 1, precipitation, and filtration. the word 2 of this lab is to perform a word 3 reaction, creating a word 4 that will be filtered out of the solution. the word 5 of water can then be calculated using word 6. word 1 choose word 2 choose precipitate double displacement hardness sedimentation stoichiometry objective word 3 word 4 word 5 word 6 choose

Explanation:

Water treatment steps include screening, sedimentation before precipitation and filtration. The objective of a lab could be to perform a double - displacement reaction which creates a precipitate to be filtered out. Then, using stoichiometry, the hardness of water can be calculated.

Answer:

[word 1]: Sedimentation
[word 2]: Objective
[word 3]: Double displacement
[word 4]: Precipitate
[word 5]: Hardness
[word 6]: Stoichiometry
