The balanced chemical equation for the reaction is as follows;
Ca(OH)2 + 2HCl —> CaCl2 + 2H2O
The stoichiometry of Ca(OH)2 to HCl is 1:2.
Number of Ca(OH)2 moles reacted = 0.00100 mol
Therefore number of HCl moles that should react with base is double the amount of moles of base reacted.
Number of acid moles in 25.00 ml
= 0.00100 mol x2 = 0.00200 mol
Correct answer is 0.002 mol
Answer:
All atoms and ions of iron have 26 protons. Iron's atomic number is 26. Atoms don't gain or lose protons. The atomic mass of this ion is 56, which is the sum of its protons and neutrons.
Answer:
the basic unit of a chemical element.
Explanation:
Kind of this is probably wrong Mass weight of solid, volume weight of liquid?
