(a) lonic bonding
Explanation:
The Strongest chemical bond is the ionic bond ,
Because ionic bond is bound by strong electrostatic interactions ,

Hence , ionic bond is stronger than covalent bond .
Answer:
The density of the copper is higher than aluminium. Hence it is heavier compared to aluminium conductors it requires strong structures and hardware to bear the weight. More ductile and has high tensile strength.
...
Aluminium & Copper properties.
Property Copper (Cu) Aluminium (Al)
Density (g/cm3) 8.96 2.70
Answer:
<h2>The Invention of the Internal Combustion Engine (ICE)</h2>
Explanation:
The internal combustion engine is an engine in which ignition and combustion take place in the engine(in one place), the invention of the ICE was an integral part of the industrial revolution, as there was increasing demand for power, and manual labor could not suffice, especially during the mid 19 century.
The ICE made it possible for tasks that demand intensive power consumption to come through to reality, it was as a result of the invention of the ICE that road transportation was made easier for mankind, as the means of transport then was the use of beast of burden, now we have cars, airplanes ship, etc, essentially the invention of ICE reduced the tedious task man would have to engage in for his daily needs
