Which of the alkaline earth metal hydroxides, M(OH)2, would you expect to be most soluble in water? Least soluable?
The activation energy for the isomerization of methyl isonitrile (see figure below) is 160 kJ/mol. Calculate the fraction of methyl isonitrile molecules that has an energy of 160.0 kJ or greater at 499 K.
When a 2.00-g sample of KSCN is dissolved in water in a calorimeter that has a total heat capacity of 1.083 kJ·K-1, the temperature decreases by 0.460 K.
A tightly sealed 5.0 L flask contains argon at 69.0 deg. C and 781 mm Hg. The flask is heated until the pressure is doubled. What it the temperature of the gas.
the gas sample weighs 2.62grams then computes the molecular weight and determines the identity of the gas.
Write the structure of a different product that could have been formed if you used ethanol containing substantial amount of water instead of the absolute ethanol
Calculate the Total Cell Number, You are given a 500ml culture of Euglena from which a 1 ml sample is taken and put in 49 ml of water. Absorbance was measured on this sample but the reading was off the scale
