What are the lanthanide & actinide series?

The lanthanides and actinides together are sometimes called the inner transition elements.

Explanation:

They are called this because they come up in the periodic table after actinium

Hope this helps :)

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.

the answer is b. dilution
