The answer ispotassium (K)
Answer:
CaF2
Explanation:
Because HF is a weak acid, fluoride salts behave as bases in aqueous solution. As a Lewis base, F– accepts a proton from hydronium, which is transformed into a water. Picture is attached.
Answer:
The answer to your question is: letter C
Explanation:
a. the sharing of electrons between a hydrogen atom and another atom. This description is not for hydrogen bonding, in hydrogen bonding atoms do not share electrons, to form this bond.
b. the electrostatic interaction between an atom that has lost an electron and an atom that has gained an electron. This definition is describing an ionic bonding, not a hydrogen bonding.
c. the interaction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. This is the right definition of hydrogen bonding, because is mentioning the interaction between a hydrogen and an electronegative atom.
The appropriate answer is d. the high specific heat capacity of water. This unique quality of water makes it suitable as an organic solvent. Specific heat capacity is the energy required to change one gram of a substance by one degree. Organic processes need to be carried out at a specific temperature. The high specific heat capacity of water ensures that environmental changes in temperature.
