Reaction: 1 C3Hg + 502 ---> 3 CO2 + 4H20 (propane & oxygen makes carbon dioxide & water)
If you have 0.5 moles of propane (C3H3) & react it with oxygen, how many moles of
CO2 are made?

For ai it's atomic number is 13 and it's mass number is 27 how many neutrons does it have

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.

In the experiment you asked to react hydrochloric acid and with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision.
