Answer:
pH = 8.1
Explanation:
Assuming that we are at 25 degrees Celsius, pH + pOH = 14.
We can then plug in the given pOH and solve for pH:
pH + pOH = 14
pH + 5.9 = 14
pH = 14 - 5.9 = 8.1

The spherical object will float and the square object will sink to the bottom of the fluid as it has greater density. :)
Answer:
of the reaction is -6313 kJ/mol
of the reaction is -6312 kJ/mol
Explanation:





Therefore,
of the reaction is -6313 kJ/mol.
The chemical reaction in bomb calorimeter is as follows.




Therefore,
of the reaction is -6312 kJ/mol.
Carbon has 4 valence electrons so to gain a noble gas electron configuration, which has 8 valence electrons and is the most electrically stable, carbon needs 4 more electrons.
