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:
The mouth uses both mechanical and chemical digestion. Mechanical digestion involves physically breaking down the food into smaller pieces (using the jaw/teeth). However, chemical digestion then takes over and starts breaking down the food into simpler nutrients that can be used by the cells using saliva, which is naturally made within the mouth.

Ground is used for agriculture, sink water, hose water, and even drinking water (from the aqueducts).
After reacting, place a red moist litmus paper into the final solution and the litmus paper will turn blue. This indicates that the solution is alkaline.
Alternative methods
Using universal indicator
using phenophtalein
using bromothyl blue
using methyl orange
use pH probe connected to a data logger
The answer is it tends to be more negative down a group. This is because as you go down the periodic table, the elements have more electron shells in their atoms. This makes the outermost shells less attracted to the nucleus due to their greater distances from the nucleus. Therefore, these shells are less likely to attract electrons (hence lower electron affinity) and are even more likely to lose electrons from their outer electron orbits.
