ic system because two-thirds of the ngaged in the cultivation of land. Agriculture not only helps to feed the large population, but it also supports the principal manufacturing industries with raw materials.
Answer:
Metals are good conductors of electricity, therefore, they are used for making immersion rods. 3. Copper is less reactive than zinc. Therefore, it cannot displace zinc from its salt solution.
1.A)Metals are also malleable, which means that they can be hammered into very thin sheets without breaking. They are ductile, which means that they can be drawn into wires.
B)GRAPHITE is the only non-metal that conduct heat and electricity . :)
2)When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide. A compound is a material in which atoms of different elements are bonded to one another. Oxygen and magnesium combine in a chemical reaction to form this compound.
