The cis-1,4-di-t-butylcyclohexane [cis-1,4-di(1,1-dimethylethyl)cyclohexane] and trans-1,4-di-t-butylcyclohexane stereoisomers can both be drawn but only one of them can easily be synthesized. Draw both conformers and suggest which of them is stable. Suggest a reason why the unstable conformer is unstable.
Assume that no heat is lost to the surroundings or to the coffee cup itself. Assume that the mass of the solution is equal to the mass of the water.
A stainless steel spoon weighs 25.2 g and is at a temperature of 18.5 oC. It is immersed in 81.7 mL of hot coffee (T = 84.0 oC) in a Thermos flask.
A volume of water was delivered using a buret and experimentally determined to have a mass of 2.00-g. What was the final volume of water on the buret if the inital was 0.44-mL? [assume the density of water is 1.00g/mL]
If I add 1.65 L of water to 112 grams of sodium acetate...What is the molality of NaC2H3O2 in this solution?
