A unknown liquid is insoluble in water and soluble in cyclohexane and alcohol with a boiling point of 110 C What is the substance?
Calculate ΔH and ΔStotal when two iron blocks each with mass of 1.00kg, one at 25'C and one at 250'C are placed in contact with each other in an isolated container.
Calculate the mass of AgNO3(s) that must be added to 0.500 L of a solution of 0.154 M NaClsolution to precipitate ‘all' of the chloride ion. The ‘all' means that we want to add the same number of moles of silver ion.
Consider a glass of 262 mL of water at 28°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
Magnesium reacts with iron(III) chloride to form magnesium chloride and iron. 3Mg(s) + 2FeCl3(s) => 3MgCl2(s) + 2Fe(s)
