What’s the conclusion

Why are the trends and exceptions to the trends in ionization energy observed?

How many moles of carbon dioxide will form if 2.5 moles of c3h8 is burned

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.
