Answer:
A. Elastic
Explanation:
an elastic collision is one which there is no overall loss of kinetic energy
Answer:
Explanation:
Since 1 mole of Fe reacted and 1 mole of Cu is produced.
Mass = molar mass × number of moles
Molar mass of Fe = 56 g/mol
Molar mass of Cu = 63.5 g/mol
Mass of Fe = 56 × 1
= 56 g
Mass of Cu = 63.5 × 1
= 63.5 g
Therefore, the statement is not correct.
8 electrons makes a full shell in an atom
Answer:
electric balance, goggles, beaker
Explanation:
I did it and got it right
Explanation:
First I'm going to draw the structure of the neutral calcium atom and the structure of the chlorine atom.
Now I'm going to draw only the valence shells of ions that participate in ionic bonding:
So Ca2+ will donate 2 electrons for both 2 atoms of Chlorine, forming CaCl2.
