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>.
Answer:
Volume of acid in the solution, 53.87 mL
Explanation:
This can be solved with a simple formula
(Volume of solution which is acid / Total volume) . 100 = % acid
(Volume of solution which is acid / 341 mL) . 100 = 15.8
Volume of solution which is acid / 341 mL = 0.158
Volume of solution which is acid = 0.158 . 341 mL
Volume of solution which is acid = 53.87 mL
No of moles= mass/atomic mass
no moles of potassium= 65g/39.8= 1.6moles
