Question

1. What are elements?How are they different from mixtures?

2. Aluminium is used in making utensils used for cooking food? Which property of Aluminium is being used here?

3. Can we use Carbon to make wires for household usage? Why or why not? Explain

4. Define malleability and Ductility?​

Answer 1

Answer:

1. The individual components of a mixture can be physically separated from each other. Chemical compounds are very different from mixtures: The elements in a chemical compound can only be separated by destroying the compound.
2. Good thermal conductivity, malleability, light weight and high melting point are the properties of aluminium due to which it is used for making cooking utensils.

4.A malleable material is one in which a thin sheet can be easily formed by hammering or rolling. ... In contrast, ductility is the ability of a solid material to deform under tensile stress. Practically, a ductile material is a material that can easily be stretched into a wire

Answer 2

Answer:

Element is defined as the substance which cannot be broken into simple substances by any physical or chemical change .It was defined by Robert Boyle in the year 1661
