How can you maximize the use of useful materials that you have identified? empty bottles, fruits peeling,old news paper
The way to maximize the use of materials identified is by identifying the 3 R's of waste management which are Reduce, Recycle and reuse .
Explanation:
For example, when we check through the materialsempty bottles, fruits peeling,old news paper them can be Reduce, Recycle and reuse.
The plastic bottles can be recycled i.e converting the waste plastic materials into another useful materials like fabric, shoes, mats.
Fruits peeling can be reuse as composts for plants. These can be allow to be decompose which serve as plant compost to release nutrients for plants growth.
Old newspapers can be reduced by been sold to junks shop and some cash can be earned from it.
You can maximize the useful materials that are being identified by recycling, reusing, and reducing them.
Let assume that the unknown materials in question are:
empty bottles, fruit peel, and old papersThe materials in question are called waste materials but they should not be discarded since they have many other purposes.
Recycling is an act or a process of changing waste materials into reusable products. For example, empty bottles can be recycled to produce varieties of products such as birdfeeders, pencil cases, T-shirts, etc.
Fruit peel can be reused on farmlands as compost manure. They can be used to increase the fertility of farm crops.
To reduce a material means to bring smaller in size. Old papers can be reduced in making paper mache arts. This can add creativity and beauty to the world of art.
In conclusion, you can maximize the useful materials that are being identified by recycling, reusing, and reducing them.

12. Which of these elements would most likely be a shiny, gray-colored
solid at room temperature, conduct electricity, and dent when hit with a
hammer? *
Answer:
Metal.
Explanation:
If there are more specific options choose the one that is classified as a metal on the periodic table :)
The grey-colored shiny element that conducts electricity has been Aluminum metal.
The periodic table has been consisted of metals, metalloids, and nonmetals.
The metals have the properties of conducting electricity, as well as they are the shiny compound that existed to be solid at room temperature. The metals have been lustrous and ductile and malleable.
Thus. metals have been the compound that has been dented with the hammer, conducts electricity, and is shiny. The grey-colored metal has been Aluminum.
Thus, the grey-colored shiny element that conducts electricity has been Aluminum metal.

okay another question from my test I’m almost done sorry for spamming I just gave up on that class because I’m pretty sure it can’t get worst :D
Answer:
The Answer is C.
Explanation:
The Mass number is the total number of nuetrons and protons in the nuclues. So there are 84 particles in the nuclues because the mass number is 84. Also because the atomic number is 36 that means that there are 36 protons. It also happens to mean that there are 36 electrons because the amount of the protons is equal to electrons unless stated otherwise. Because electrons reside outside of the nuclues there are 36 particles outside the nueclues.

A wooden block has a mass of 562 g and a volume of 72 cm 3 . What is the density?
The density of the wooden block is 7.81 g/cm³
Density is related to mass and volume by the following equation:
Density = mass / volumeWith the above formula, we can obtain the density of the wooden block as follow:
Mass of wooden block = 562 g
Volume of wooden block = 72 cm³
Density of wooden block =?Density = mass / volume
Density = 562 / 72
Density = 7.81 g/cm³Therefore, the density of the wooden block is 7.81 g/cm³

Using a ruler to measure the length of a stick is an example of
1) extending the sense of sight by using an instrument
2) calculating the percent of error by using a proportion
3) measuring the rate of change of the stick by making inferences
4) predicting the length of the stick by guessing
Answer:
The answer would be 1) extending the sense of sight by using an instrument.
This is because you are using a ruler (your instrument) to see how long the stick is. It can't be 2) calculating the percent of error by using a proportion, because you aren't calculating the percent of error from the stick. It also can't be 3) measuring the rate of change of the stick by making inferences, because you are using a ruler, making it the exact measurement, not making an inference. It can't be 4) predicting the length of the stick by guessing, because again, you're using a ruler to see the exact measurement of the stick.
