41.6g/cm3 would be the density of the bread
Hello, Ginamuhs2!
The oxidizing agent in 2H2S + 3O2 → 2SO2 + 2H2O is the oxygen.
I hope this helps;)
PH + pOH = 14
pH
= 14 - pOH
= 14 - 11
= 3
pH = 3
- lg [H+] = 3
[H+]
= 0.001
= [HNO3]
= 1 x 10-3 M
Answer:
The central atom has 3 electron domains.
Explanation:
According to the Valence Shell electron pair repulsion theory (VSEPR) put forward by Gillespie and Nyholm in 1957, the shape of a molecule is determined by repulsion between all the electron pairs (electron domains) present in the valence shell.
The electron pairs or electron domains are known to position themselves as far apart in space as possible in order to minimize repulsions.
Hence, when the central atom of a molecule contains three electron domains, they are positioned at an angle of 120° from each other to minimize repulsions. Hence the answer.
