(10) 9. You have a container of liquid nitrogen (N2) from the LN2 plant in the Reichardt building, and you want to take this container (called a dewar) to the kitchens down at Hutchinson to make liquid-nitrogen ice cream. The dewar contains 6.0 L of liquid nitrogen. Liquid nitrogen is-196 °C. You put the dewar on the back seat of your Toyota Corolla...

A liquid-phase mixture of 450 mL of acetic acid, 300 mL of ethanol, 2.00 mL of water, and 2.00 mL ethyl acetate are mixed together at 298 K, where the following reaction will occur: CH3COOCH2CH3 +H2O CH3COOH +CH3CH2OH, Kc = 3440 Will the reaction occur from left-to-right or right-to-left (as written)? Please support your answer. (Hints: Can you calculate concentrations of the chemical species initially in appropriate units. Starting with the densities, i.e., specific gravities, and volumes, molar amounts...

Can the two drugs furosemide and midazolam be mixed in the same IV bag? explain the reasoning for your answer using chemical compatibility from molecular structure and an acid-base assessment. Also, consider the bulkiness of both drugs and the fact that low molecular weight salts have better solubility.
