Chemistry is a very hard subject in my opinion
Absolute zero is measured in kelvin and kelvin is -324 degree celsius witch turns most elements turn solid
There will be a maximum of 2 electrons that can <span>occupy a single molecular orbital. They will have opposite spins. Hope this answers the question. Have a nice day. Feel free to ask more questions. Have a nice day.</span>
Answer:
Ka2 values should be used in obtaining pKa2 in the Henderson–Hasselbalch equation
Explanation:
During first dissociation from H3PO4 to H2PO4-, ka1 will be used, and from H2PO4-to HPO4-, ka2 values will be used, hence a buffer solution containing H2PO4-and HPO4-will use ka2 in obtaining pKa2 in the Henderson–Hasselbalch equation.
