Calculate the ph of 100 ml of a buffer solution that is 0.063 M in phenol C6H5OH (Ka =1.3x 10^-10) and 0.13 M in NaC6H5 after (a) 0 ml and (b) 10 ml of 0.75M HCL is added

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

the correct option is c.

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
