2. The type of dynamic equilibrium between different physical states of a pure substance in a closed system is called: A) Solubility Equilibrium B) Phase Equilibrium C) Chemical Equilibrium D) Homogeneous Equilibrium

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

fe 55.85 g/mol and h2o 18.02 g/mol.

that's what i got you can count the number of atoms
