Explanation:
Covalent compounds (solid, liquid, solution) do not conduct electricity. Metal elements and carbon (graphite) are conductors of electricity but non-metal elements are insulators of electricity. Ionic bonds are the electrostatic attraction between positive and negative ions.

The weak base carbonate reacts with the water forming bicarbonate and the hydroxide ion.
<h3>What is a weak base?</h3>
The weak bases are given as the compounds that have the inability to get completely dissociated in water.
The carbonate is given as the weak base, as in water it remains constituted in the form of a bond with oxygen.
The reaction of water with the carbonate ion is given as:

Answer:
Proper waste management allows for separation at the source and subsequent recycling, which allows materials that required energy and raw materials to be reincorporated into the production cycle, as the finished material is incorporated back into the production cycle, the amount of energy required for the production of <u>the final product is less than if it were made from the start</u>.
Explanation:
A very useful example of energy conservation through waste management is the following: suppose that in your school they do proper waste management, therefore materials such as cardboard, paper and plastic are separated appropriately and are subsequently donate or sell to a company that is dedicated to recycling these materials, plastic is a material that requires a lot of energy, first for its elaboration and later for the creation of the final product such as the packaging of a shampoo or a chair, however, as the recycled plastic is already manufactured, <u>the recycling company saves said energy, which only requires crushing the obtained plastic and selling it to a company that produces the final product</u>.
