HELPPP ASAP Part 1: Name the type of chemical reaction that occurs when calcium hydroxide (Ca(OH)2) reacts with nitric acid (HNO3). Part 2: Explain why zinc (Zn) would react with lead nitrate (PbNO3) but not with calcium chloride (CaCl2). (10 points)

it is an acid base reaction. the salt formed is calcium nitrate why zinc wont react with lead is that it is more reactive than calcium

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
