Assuming that the total pressure of the gases is 1.68 atm and that their mole ratio is 94 : 4.0 : 1.5 : 0.50, calculate the partial pressure (in atmospheres) of each gas. Express your answer using two significant figures. Enter your answers numerically separated by commas.
After you filter off the component that does not dissolve in dichloromethane, you will transfer the dichloromethane to a separatory funnel and wash with aqueous 1 M sodium hydroxide. Which layer is the dichloromethane layer
Adenosine monophosphate (AMP) is a regulatory molecule in metabolic processes such as glycolysis and gluconeogenesis. For example, it stimulates the glycolytic enzyme phosphofructokinase, and therefore ATP production, and it inhibits the gluconeog..
upon catalytic hydrogenation unknown Z gives cyclooctane. Oxonolysis of Z followed by reduction with dimethyl sulfide, gives a three0carbon dialdehyde and a five-carbon dialdehyde. Draw the stucture of Z.
When determining the pressure of dry hydrogen gas, explain how the measured atmospheric pressure is corrected for the presence
