Ionic bond:
A bond resulting from the attraction between oppositely charged ions; one atom gives another electrons.
Covalent Bond:
A bond resulting from the shaing of pairs of electrons between two atoms.
(+1) + (-1) = 0
Carbon and Hydrogen are present in all organic compounds !
Answer:
0.13 g
Explanation:
mass of aluminum required = ( Dislocation length) / ( Dislocation density) × (density of metal)
3000 miles to cm ( 1 mile = 160934 cm) = 3000 miles × 160934 cm / 1 mile = 482802000 cm
density of Aluminium = 2.7 g /cm³
dislocation density of aluminum = 10¹⁰ cm³
mass of aluminum required = (482802000 cm × 2.7 g/cm³) / 10¹⁰ cm³ = 0.13 g
