0.157 moles of Hg will be produced from 34.0 g of HgO.
<u>Explanation:</u>
2HgO → 2Hg + O2
Molar mass of HgO = 216.59 g / mol
34.0 g / (216.59 g / mol) = 0.156979 mol HgO
1: HgO: Hg = 1 coefficient ratio ( mol defense ) because ,
0.156979 mol HgO = 0.156979 mol Hg
= 0.157 mol of Hg.

Answer:The answer is 8-14
Explanation:It can range from 9-10 or
or above to 14 depending on the amount of leached wood ash(lye) a.k.a potassium carbonate which is an alkalline compound
A spontaneous reaction favours the product formation and increases the entropy of the isolated system. The sign of the entropy change will be negative as the product formation is less random.
<h3>What is entropy?</h3>
Entropy is the degree of the disorder or randomness that occurs in the system that lacks available energy and cannot convert the mechanical energy or work.
The entropy of the reaction will be negative as the reactants are present in the gaseous state and the product formed is solid. The product formation was spontaneous and less random.
Therefore, option a. entropy will be negative as product formation is less random.

Answer:
²³⁵₉₂U
Explanation:
The nuclear symbol of the nuclei is ²³⁵₉₂U.
The uranium nuclei has;
mass number = 235
atomic number = 92
To write the structure of the atom;
The subscript before the symbol of the atom is the atomic number
The superscript is the mass number
So;
²³⁵₉₂U is the symbol of the nuclei.
Answer:
the mass is m ' a so yes a and m
Explanation: first off ' m
