In a reaction, 34.6 g of chromium(III) oxide reacts with 12.3 g of aluminum to produce chromium and aluminum oxide. If 23.7 g of chromium is produced, what mass of aluminum oxide is produced
Please explain why the Miller & Urey experiment was so important? What did that experiment tell us, How did it relate to the origin of life
suppose that a student performing an experiment mistakenly calibrated the pH meter using pH 6 instead of a pH 7 buffer. As a result all pH meter readings were too low.
Calculate the pH of a buffer solution prepared by dissolving 0.20 mole of sodium cyanate (NaCNO) and 1.0 mole of cyanic acid (HCNO) in enough water to make 1.0 liter of solution. [Ka(HCNO) = 2.0 &time
