Assume every breath a person took is 0.5L of air, figure out how many grams of Oxygen you consume at every breath. Now assume that you breathe 30 times per second, figure out how long it took for you to consume all the oxygen in a sealed room of 1..
Before developing the dead-weight gauge, he worked in a mine shaft, and used a mercury manometer for measurements of pressure to more than 400 bar. Estimate the height of the manometer required.
Analysis of a 1.000 g of the oral hypoglycemic agent metformin yielded 0.3720 g of carbon, 0.0858 g of hydrogen, and 0.5422 g of nitrogen.
A student allowed several air bubbles to enter his eudiometer tube. He ignored the error and proceeded with the experiment. What effect will this error have on his final result? Explain your rationale.
For equilibrium calculations involving metal complexes with EDTA, it is convenient to calculate the fraction of EDTA that is in the completely unprotonated form, Y4- (see the figure). This fraction is designated ?Y4-. Calculate ?Y4- at the followi..
