Simply look at the periodic table and fill in what you know based on the table
The number of protons = atomic number
The number of electrons, Which is the same as the atomic number for atoms.
The number of valence electrons that is given by the group that the element is in, the top number of each column in the periodic table.
Answer:
Hydrogen bonds are totally different to both covalent bonds and ionic bonds. Hydrogen bonds are intermolecular bonds, that means they occur in between two molecules. ... When H atom is close to O,F, N atoms those atoms can attract H atoms electrons temporarily, thus making a weak bond.
Explanation:
W=0.360
p=1.18g/mL
pH=2.12
v=14.0 L
M(HCl)=36.46 g/mol
v₀-?
1) pH=-lg[H⁺]
[H⁺]=c(HCl)=10^(-pH)
n(HCl)=v[H⁺]=v*10^(-pH)
2) n(HCl)=m(HCl)/M(HCl)=wv₀p/M(HCl)
3) v*10^(-pH)=wv₀p/M(HCl)
v₀=v*10^(-pH)M(HCl)/(wp)
v₀=14.0*10^(2.12)*36.46/(0.360*1.18)=9.115 mL
Approximately 9.1 mL of concentrated solution required.
Answer:
Prior to his death, Mufasa explains to Simba that “when we die, our bodies become the grass, and the antelope eat the grass, and so we are all connected in the great circle of life” . This is an ecological metaphor that goes beyond the human experience, intertwining the supernatural and physical world.
