Histidine has three ionizable functional groups. write the equilibrium equations for its three ionizations and assign the proper pka for each ionization. draw the structure of histi- dine in each ionization state. what is the net charge on the his- tidine molecule in each ionization state?

since electrons are negative the answer is neagtaive

i dont know the answe

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
