Question

Precycling means making environmentally sound decisions (5.0 points)

Answer 1

Answer:

Q1 - at the store before taking the product home, because "pre" in precycling stands for making environmentally sound decisions BEFORE buying a product.

Q2 -  in many household products, such as cleaning products, the ones that are used for doing laundry, medicine, etc.

Q3 - Environmental Protection Agency, which aims to protect and conservate the natural resources in the U.S.

Q4- the highest recycled content, because then you'd be contributing for the recycling cicle avoiding unnecessary waste of other materials.

Q5 - corrosive, since they destroy other materials (or cause corrosion).

Q6 - lower grade of recycling, because the result of this process are material that are less valuable than the former one.

Q7 - taking it to your local Household Hazardous waste station, since this place will dispose of your waste in a safe way, and give it a correct destination.

Q8- 100% recyclable and not expensive to do so, also it's very common to recycle it since this process is not complex or expensive.

Q9 - computer paper, because the wax in fast food wrapers make it difficult for it to be recycled, as well as the wax in juice boxes and the pet food bags that contain plastic and aluminium layers below the paper layer.

Q10-  waxed milk/juice cartons, plastic laminated packages, since the layers in those papers and the wax in it can't be removed properly in simple recycling processes.

Q11- reduce, reuse and recycle, to optimize and diminish the use of some materials and then reduce pollution and waste volume.

Q12 - fertilizer, as long as it has natural components. Industrial fertilizers are also very hazardous because they might contain toxic products in it that can pollute water and soil.

Q13- Letter R, for recycle! This is a strategy to stimulate recycling processes and the correct disposal of such materials.

Q14 - toxins, since they are toxic for an organism and might cause death after long exposure.

Q15 - recycle would be the most efficient way to eliminate waste, since we transform all the material used in other materials or in simpler compounds, therefore not letting waste accumulate.

Q16 - baking soda, lemon oil, and borax, since those household items can be decomposed naturally and won't pollute the environment.

Q17 - not poisionous to humans, since toxic products are considered to have the potential to harm human beings.

Q18 - toxins, because they are capable of harming living beings.

Q19 - all of the above, since they are all highly alkaline and can, therefore, cause corrosion.

Q20 - Ammonia, which causes an exothermic reaction liberating chemical fumes.

Answer 2

Q1)2 precycling means pre-recycling; it is the act of deciding which products to acquire or discard to avoid excessive waste while shopping at the store. Q2)3 the other answers use the word "only", with an exclusive meaning, which is wrong, because toxic chemicals are present in many places and products. Q3)4 The Environmental Protection Agency is the official Federal agency protecting the environment and related human health issues. Q4)4 The other answers aren't good enough criteria to improve recycling. Q5)4 Corrosives "eat away" at other material. Toxins are poisonous substances which do not have effect on every kind of material (more likely to react with organisms), reactives are substances which give response to a stimulus or another chemical, without compulsorily "eating" it away, flammables are prone to be burnt when in contact with certain substances. Q6)1 Downcycling is the process of recycling, producing products with lower quality than its originals. Q7)1 The other answers are what actually would lead to poisonous and dangerous pollution, in fact they are strongly advised not to be done. Q8)1 Aluminum is actually a competitive material for its full recyclable properties, which don't lose quality. Q9)1 All kinds of office paper can be recycled, including computer paper. Q10)1 All kinds of hybrid/mixed paper cannot be recycled. Q11)2 The other answers are wrong as they are neither the right order or the right terms. Q12)4 Fertilizer is not hazardous waste as long as it is natural. Q13)1 Q14)1 All these can harm human health, but toxins are mainly the chemicals producing poisonous vapors. Q15)4 All these methods are efficient in their own way, but reducing the use or acquirement of products is what starts the chain to have less waste. Q16)1 The other answers are not at all natural substances, on the contrary of answer 1. Q17)1 Nontoxic implies that it won't directly harm human's health, but there is actually no specific appliable definition to this adjective. Q18)1 Toxins are poisonous products per se, so it is the most correct answer. Q19)4 All of the choices are highly alkaline chemicals, therefore corrosive. Q20)2 Ammonia mixed with bleach creates deathly vapors.
