An aqueous solution has a hydroxide-ion concentration of 1.0x10^-3M. What is the pH of the solution? a.11
b.3
c.-3
d.7

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.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

you need to have a picture of the atom that way we can answer it
