Answer:
B.The potential energy decreases while the kinetic energy increases.
2.-> At the equivalence point, the pH = 7.00 for strong acid- strong base titrations.
3.-> A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions.
All atoms of a single element have the same mass
Answer:
24.5 moles of mercury are produced
Explanation:
The descomposition of mercury(II) oxide, occurs as follows:
2HgO → 2Hg + O₂
<em>Where 2 moles of HgO produce 2 moles of Hg</em>
<em />
In other words, the ratio of descomposition of HgO/Hg is 2/2 = 1:1
That means, if 24.5 moles of mercury(II) oxide descompose:
<h3>24.5 moles of mercury are produced</h3>
Answer:
it is 1,4
