What is the change in heat (NOT change in temperature) for a 35.0 g sample of aluminum that cools from 70.0°C to 25.0°C if aluminum has a specific heat capacity of 0.900 J/g°C? (answer is in joules with 2-3 sig figs) (MAKE SURE you check the sign of your answer, is the aluminum gaining or losing heat?)

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
