What information does a phase diagram give

How many electrons does oxygen need to complete its octet? a) 1 b) 2 c) 3 d) 4 e) 6

You slide the copper bar to the right and at time t = 0 you release the bar when it is a distance x from the right end of the apparatus. at that instant the bar is moving to the right with a speed v.

Write the proper charges so that an alkali metal, a noble gas and a halogen have the same electron configurations.

What type of nuclear decay is shown by the reaction below? 238/92 U - - > 4/2 HE + 234/90 TH

Determine which change of state is being described in this passage. As the temperature decreases, the atoms lose energy. The atoms begin to move slower. They are held together by attractive forces, but are still able to slide past each other.
