A barometer is used to measure atmospheric pressure contains mercury with a density of 13,590 kg/m^3 . If the local atmospheric pressure is 101 kPa and acceleration due to gravity, g is 9.81 m/s^2 , determine the height of the mercury column in a barometer, L in "mm Hg" and in "inch Hg".
Use this equation to calculate the wavelength of the photon emitted in units of nanometers for the following transitions.
A student takes a mixture of sugar (C6H12O6), diamond powder (C) and BaCO3, separates the mixtures and recovers 1.75g sugar, 0.86g diamond powder and 2.29g BaCO3(s). Student % recovery was 96.46%, less than the initial amount of mixture they start..
