Suzy's science class is studying changes in particle motion during phase changes. suzy is asked to add a few pieces of dry ice to a flask and cover it with a balloon. after a few minutes she observed the balloon starting to inflate. how can she explain this?

Smog is the term used to describe the combination of fog and smoke

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)

Scientist think that animals with remarkably similar embryo development probably shared a common ancestor
