False you should never taste something if you don’t know what it is
H and Br are both non-metals which means the bond that comes in between them is covalent. If the composing elements are non-metal and metal, then the bond should be ionic. In this case, HBR is considered polar because the Br atom pulls on the electron much harder than the H atom. Answer is C.
Answer with Explanation:
Ionic bond:It is that type of bond which formed between negative and positive ions.
Hydrogen bonding:Hydrogen bonding formed between hydrogen and high electronegative elements.
Dispersion force:It is weakest intermolecular force.It is temporary attractive force.When electrons of two adjacent atoms occupy positions that make the atoms temporary dipoles.
NaCl: In which Na is positive ion and Cl is negative ion.
Therefore, NaCl is ionic.
HF:F is highest electronegativ elements.
HF:Hydrogen bonding
HCl: Hydrogen bonding
:Dispersion
Answer:
the significant of carbon.A compound found mainly in living things is known as an organic compound make up the cells and other structures of organism and carry out life processes.Carbon is the main element in organic compound,so carbon is essential to life on earth
