Answer:
Jewelry
Explanation:
Gold and silver are metals which are malleable, ductile, and lustrous. Also they are noble metals. since they are noble metals they are not affected by acid, oxygen, atmosphere and etc. hence gold and silver are used or suitable for making jewlery.
It's the second one. Their body activity decreases, mostly because they're sleeping and they conserve the food in their bodies for long periods of time.

A
The number of electrons/protons is the one that determines the atomic number of an element.
Metals are to the left of the zig-zag, nonmetals are to the right, and metalloids lie on/beside the line.
Answer:
Molarity = 0.5 M
Osmolarity = 0.5 x 2 = 1 Osmpl.
Molecules of Cl2 = 6.02 x 
/ 4= 1.505 x no. of molecules
Explanation:
If we add half mole in 1L volume than molarity will obviously be 0.5 M.
The osmolarity is molarity multiplies by number of dissociates of solute that for CaCl2 are 2. So, 2 x 0.5 = 1
Half will be molecules of Ca and half will be of Cl2 for 0.5M.
