Formic acid, hcooh, occurs naturally in the venom of bee and ant stings. it was originally isolated by the distillation of ant bodies. what are the changes in free energy, enthalpy and entropy and the sign of work for the following process carried out at 120.0o c. the boiling point of hcooh is 100.8o c. hcooh (g) → hcooh (l)

What is the difference between a substance "getting wet" and "being dissolved" in a liquid at the particulate level?

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
