Pentane is a flammable and volatile liquid. If 2 mol of pentane is burned in 8 moles of O2.) based on the following chemical equation What reactant is limiting?

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

Calculate the expected ph values of the buffer systems from the experiments (a,b,c,d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

Which of the following is true for the actual yield of a reaction? it is always calculated as a ratio. it is the yield from the excess reactant. it is the yield from the limiting reactant. it is always less than the theoretical yield.
