You first need to write the balanced chemical reaction for what is going on.
Ca(OH)₂+2HCl→2H₂O+CaCl₂
After you make the balanced chemical reaction, First you find the moles of HCl used. To do this multiply 0.0375L by 0.124M to get 0.00465mol HCl. Then you multiply 0.00465mol HCl by (1mol Ca(OH)₂)/(2mol HCl) to get 0.002325mol Ca(OH)₂. Finally to find concentration of Ca(OH)₂ used you divide 0.002325mol by 0.020L to get 0.116M Ca(OH)₂.
Therefore the concentration of the unknown solution of Ca(OH)₂ was 0.116M.
I hope this helps. Let me know if anything is unclear.
Answer:
i have no clue
Explanation:
umm cause i have no clue sorry lol but good luck
A, milligrams because rice is very small therefore you'd need to use a very small unit of measurement.
I am pretty sure it is density
Bronsted base means proton or hydrogen ion acceptor.
The more negative the compound is the more is the chance of accepting hydrogen ion.
B, C and D are negatiave
While is A is neutral. SO it is the weakest
