Answer:
it's 4 or fish and I think
This would create a convergent boundary
Answer with Explanation:
Density of copper(Cu)=
Density of zinc(Zn)=
Atomic mass of copper=
Atomic mass of zinc=65.38 g
We know that
Volume=
Using the formula
Volume of copper=
Volume of zinc=
Volume is inversely proportional to the density.
Pre -1982 penny made by copper and post-1982 penny made by zinc.
Therefore, volume of post-1982 penny is greater than the volume of pre-1982 penny because density of zinc is less than the density of copper.
Molecular is existent due to being made out of molecules, and thus taking up space until a container cannot hold more.
Ionic substances are a little different they are made out of energy, thus taking up only the amount of energy a certain area can handle. Ionic substances also will show motion of energy as well.
