Butane (C4H10) is burned to completion in air. How many moles of air are used for each mole of butane if 18% excess oxygen is used
The product in the 3rd step of this multi-step synthesis, p-aminobenzoic acid (PABA), was a common ingredient in sunscreen lotions. PABA is such an effective sunscreen due to the many resonance structures that can be drawn for this molecule.
what color will the solution appear? If 0.100 M NaOH is slowly added to the HCl sample, in what pH range will the indicator change color?
