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

it is reliable if two scientists recorded it

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
