Calculate the number of molecules of Al2O3, that are produced when 5.5 mol of Fe is produced in the following reaction. 2Al(s) + 3FeO(s) + 3Fe(s) + Al2O3(5) 2.4 x 1023 molecules 1.1 x 1024 molecules b. 1.2 x 1023 molecules d. 3.6 x 1023 molecules ​

How many moles of gas are present if p=11 atm, v=12l, t=185k?

Compare and contrast the bohr model and the electron cloud models of the atom.

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.
