Two 20.0 g ice cubes at −15.0 ∘C are placed into 255 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

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

Answeropposite;

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
