I'm doing a virtual lab in which I'm trying to separate tin, aluminum, and steel. Does the order in which I heat them at 300 degrees and observe their magnetism matter? The lab says the three are isolated when they are heated to 300 degrees and then placed under a magnet, but not in the other way around.
Suppose you are given 150 mg of an unknown mixture that contains three compounds, and you are told to separate the compounds using column chromatography
-an experiment was done using NaCl and KCl for solubilty purposes, would the results be different if Nacl and LiCl were used instead?
determine how many grams of CaH 2 are required to generate 145 Litres of hydrogen gas if the pressure of hydrogen is 825 mm Hg at temperature of twenty one degree Celsius? .
One mole of an ideal gas undergoes an isothermal reversible expansion, doing 1 kJ of work and doubling the volume. What is its final temperature? How much heat was added to the gas
water in order to raise the boiling point of the solution by 0.5 C? Assume the ideal van't Hoff factor for NaCl.
Problem- The work function of an element is the energy required to remove an electron from the surface of the solid. The work function for palladium is 503.7 kJ/mol (that is, it takes 503.7 kJ of energy to remove 1 mole of electrons from 1 mole of..
