No, they do not. Carbon dioxide has a linear geometry because the lone pair and bond pair repulsion cancels out; however, water has a bent structure because only the oxygen atom possesses a lone pair which brings the bonding electron pairs closer.
        
             
        
        
        
Answer:
Ag has atomic number 47 = 47 protons and 47 electrons. mass number is 108, neutrons = 108 - 47 protons = 61 neutrons.

Non-polar covalent
Explanation:
Propane is made up of non-polar covalent bonds and it can be expected to dissolve in hexane and to not dissolve in water. 
Propane is an hydrocarbon gas. 
It forms by sharing of electrons between two atoms with very low electronegativity differences. 
This differences results in equal sharing of the shared electron. Therefore they form a non-polar covalent bond. 
Water is a polar covalent compound and cannot dissolve compounds that are not polar like propane. 
Propane will only dissolve in a like substance like hexane which is equally non-polar.
