Hydronium ions are H30+, and pH = -log10[H+]
<span>As H+ ions in solution exist as H3O+ ions, the lower the pH, the higher the concentration of H30+</span>
Answer:
the energy required to do work
Answer:
Just under 1 tsp
Explanation:
This is a situation where dimensional analysis is helpful....
156 mg / (80 mg / 2.5 ml * 5 ml / tsp ) =
156 mg / ( 160 mg/tsp) = .975 tsp ~~~ 1 tsp
Answer:
2HCr2O7(aq) + Ca(OH)2(aq) --> 2H2O(l) + Ca(Cr2O7)2
Explanation:
A neutralization reaction produces water and a salt. Since Ca(OH)2 has two hydroxides, two water molecules are produced, which means you also need two molecules of the acid. Having two molecules of the acid also ensures that you have two dichromates on both sides.
