An ionic bond will most likely form
covalent bonds form when an electron is shared and ionic bonds form when an electron is transferred
Answer:
Melting point is the temperature at which solid and liquid phases of a substance are in equilibrium.
Boiling point is the temperature at which its vapour pressure is equal to the external pressure.
Answer:
lets set the ratio -A/HA as R:
pH = pKa + log(R,10) => pKa + log10(R)
pH = 5.5
pKa = 4.76
R => 10^(pH - 4.76)
10^(pH - 4.76) => 5.4954
Given R (-A/HA) a number bigger than 1, then the concentration of -A is bigger than HA
Explanation:
If iron atom looses 3 electrons, it forms Fe+3 (ferric) and if iron looses 2 electrons, it forms Fe+2(ferrous). Hope this helps!
The formula of chromium fluoride is CFr2.
