Ice at 0.0°c is placed in a styrofoam cup containing 352 g of a soft drink at 20.0°c. the specific heat of the drink is about the same as that of water. some ice remains after the ice and soft drink reach an equilibrium temperature of 0.0°c. determine the mass of ice that has melted. ignore the heat capacity of the cup. (hint: it takes 334 j to melt 1 g of ice at 0.0°c.)

Drag the tiles to the correct locations. each tile can be used more than once, but not all tiles will be used. one or more locations will remain empty. nitrosyl fluoride has the chemical formula nof nitrogen has five valence electrons, oxygen has six, and fluorine has seven. complete the lewis structure for this covalent compound. f n = = = . : : 0 : reset next um. all rights reserved us 2
