Refer to the measurements taken by a student below. Using these numbers, the calculated density of the aluminum bar is 3.55 g/cm3 and the calculated density of the aluminum cube is 2.79 g/cm3. How did the density calculated compare to the actual density of Aluminum on the periodic table? Give 2 reasons that might explain the difference. (10 points)

Aluminum bar:
Volume = length = 7.5 cm, width = 2.5 cm, height = 0.5 cm = 9.375 cm3
Mass = 33.27g
Aluminum cube: Volume = Aluminum cube: 8 cm3
Mass = 22.39 g

Why does asexual reproduction result in offspring with identicle genetic variation

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
