Answer:
A
Explanation:
particles are frozen and hence will vibrate in their fixed positions
An element is all the same thing. Pure, if you will.
The first one is definitely an element. The second would be a compound (it's atoms are different colors). I would say the last one is an element, since it has ll the same color of atoms.
I hope this helped you! If you have anymore questions, feel free to ask me.
Answer:
Cu^2+ (aq) + S^2- (aq) --> CuS (s)
Explanation:
Break up all the soluble compounds into their constituent ions to get the complete ionic equation, and cross off the ones that appear the same on both sides:
Cu (aq) + 2Cl(aq) + 2Na (aq) + S (aq) --> CuS (s) + 2Na (aq) + 2Cl (aq)
2Cl and 2Na appear on both sides of the arrow, so cross those out to get the net ionic equation.
Answer:
Explanation:
silicon has highest ionization energy ionization energy increases from left to right in a period because electron are added to same shell and increase in added electron shield each other poorly from the nuclear attraction
