Two 20.0 g ice cubes at −12.0 ∘C are placed into 295 g of water at 25.0 ∘C. Assuming no energy is transferred to or from the surroundings, calculate the final temperature, f, of the water after all the ice melts. heat capacity of H2O(s) 37.7 J/(mol⋅K)
heat capacity of H2O(l) 75.3 J/(mol⋅K)
enthalpy of fusion of H2O 6.01 kJ/mol

In which layer of earth do most earthauakes occur a_ inner core b_outer core c_mantle d_crust

According to each substances heat of fusion, which of the items below requires more heat to be added per gram of substance to go from solid to liquid? silver sulfur water lead

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
