How many liters of the antifreeze ethylene glycol [CH2(OH)CH2(OH)] would you add to a car radiator containing 6.50 L of water if the coldest winter temperature in your area is -37°C? (The density of ethylene glycol is 1.11 g/mL. Assume the density of water at -37°C is 1.00 g/mL.) L Calculate the boiling point of this water-ethylene glycol mixture. °C
In the Hofmann Degradation of amines an amine is exhaustively methylated with Methyl Iodide and the resultant compound treated with Silver Hydroxide and heated. An alkene is formed which is not the Saytzeff product.
Hydrangeas are flowers that retain blue coloration when grown in acidic soil and pink when grown in neutral or alkaline soil
Sodium sulfate is slowly added to a solution containing 0.0500 M Ca2 (aq) and .0280 M Ag (aq). What will be the concentration of Ca2 (aq) when Ag2SO4(s) begins to precipitate
During a lab experiment, we were to determine the relative level of saturation by adding, drop by drop, a solution of bromine in cyclohexane to oil and a fat, individually. However, the color that is supposed to be retained due to unreacted bromin..
