Answer:
Well, acutally it shouldnt..but why it should be recycled is because 1. you can use it for many nessactities such as cars and blades, and bikes
You should also recycle it for, scrap parts! so just in case if you need recycled steel ya know where to get it
Lastly, you should recycle steel because of its value. If you recycle steel then melt it, and make well i dont know, a blade out it, you might have just made something, and then think, "Well that was fun and easy, i wanna use more recycled items to build or forge things
Explanation:
Hope this helps and pls mark brainlest!
Answer:
i think because its cause pollution
Explanation:
when making steel a lot of pollution goes in the atmosphere so if you recyle the the steel we may less pollution [ im only 12 so im sorry if this was wrong]
A teacher asks students to design an activity to study the formation of inherited traits. Which activity should the students design?
Answer:
The students should create a project in which they each look at a unique trait that each have (for example, detached ear lobes) and look at their parents to see if they too have this trait. To take it a step further, look at their grandparents for this trait, and ask them about their parents and if they have this trait, this could tell them whether the trait has always, been apparent within the family, if it skipped a generation, or the genetics of one parents were more dominant then the other.
how many atoms are in 0.340 moles of sodium
The number of atoms that are in 0.340 moles of sodium is 2.047×10²³ atoms.
What is Avogadro's number?Avogadro's number is equal to 6.022×10²³ which gives idea about the number of atoms present in one mole of any substance.
i.e. In 1 mole = 6.022×10²³ atoms
Given moles of sodium = 0.34 mol
Number of atoms of sodium in given moles will be calculated as:
No. of Na atoms = 0.34mol × 6.022×10²³ atoms/mol = 2.047×10²³ atoms
Hence required number of atoms are 2.047×10²³ atoms.

When scientists create a representation of a complex process, they are

c. classifying
b. predicting
d making models.
a.
Please select the best answer from the choices provided
А.
B
D
Answer:
d making models.
Explanation:
When scientists create a representation of a complex process, they are inferring that they are making models.
A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.
The models allow a part of a body to be simply studied. Through this simple abstraction, extrapolations to other parts of the system can be deduced. This can give very useful insights into the other parts of the system. The heterogeneity of complex processes is a huge limitation to understanding them. A homogenous part can be modelled and used to understand the system.Answer:
D. making models.

What type of plate boundary (divergent, convergent, or transform) is typically
associated with sliding or shear forces?
convergent
transform
divergent
Answer:
transform
Explanation:
The type of plate boundary associated with sliding or shear forces is a transform plate boundary.
Two or more plates slides laterally past one another due to presence of shear forces acting on them.
In this margin, there is often an occurrence of earthquake. For a divergent margin, plates move apart and away from one another. This leads to the creation or formation of new crusts. At a convergent margin, two plates collides, a plate can subduct under another or both can become uplifted. Tectonic margins are known for their various activities.Answer:
convergent

Dinitrogen pentoxide is used in the preparation of explosives. If 7.93 mol of
dinitrogen pentoxide undergoes simple decomposition, what volume of Oz(9) is
produced at 48.0 °C and 125 kPa?
The volume of O₂ produced: 84.6 L
Further explanationGiven
7.93 mol of dinitrogen pentoxide
T = 48 + 273 = 321 K
P = 125 kPa = 1,23365 atm
Required
Volume of O₂
Solution
Decomposition reaction of dinitrogen pentoxide
2N₂O₅(g)→4NO₂(g)+O₂ (g)
From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :
= 0.5 x mol N₂O₅
= 0.5 x 7.93
= 3.965 moles
The volume of O₂ :
[tex]\tt V=\dfrac{nRT}{P}\\\\V=\dfrac{3.965\times 0.082\times 321}{1.23365}\\\\V=84.6~L[/tex]

Sodium Chloride is an ionic compound. Its molar mass is 58.44g. One formula unit of NaCl consists of one____, whose chemical symbol is___ and one___whose chemical symbol is___. Please help me to fill in the gaps :)
Answer: One formula unit of NaCl consists of one cation, whose chemical symbol is [tex]Na^+[/tex] and one anion whose chemical symbol is [tex]Cl^-[/tex]
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The cation is formed by the metal sodium which forms [tex]Na^+[/tex] and the anion is formed by non metal chlorine which forms [tex]Cl^-[/tex].
For a formula unit of sodium chloride, the charges have to be balanced , thus the valencies of ions are exchanged and the neutral compound result. Thus
[tex]Na^+[/tex] and [tex]Cl^-[/tex] combine to form neutral [tex]NaCl[/tex]

D. chemical composition
The question is incomplete, the complete question is;
An alcohol thermometer makes use of alcohol's changing _______ in order to measure temperature. As the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
A.

C.
chemical composition
D.
density
Answer:
D.
density
Explanation:
Every kind of thermometer makes use of a change in a particular physical property of a substance as a measure of temperature. It must be a property that changes with temperature.
Density of a substance changes with temperature. Even though the mass of alcohol in glass remains constant, but its volume increases or decreases with change in temperature leading to a change in volume and consequently a change in density of the alcohol in glass. This change is used as a measure of the change in temperature.

what are some similarities between polar and nonpolar molecules
Answer:
Explanation:
Polar bonds also often contribute to a net dipole moment of a molecule. This basically means that there are partial charges that make a molecule overall polar. One example might be water: in H20, oxygen is very electronegative, and hydrogen is less so. This means that oxygen is more negative and hydrogen is more positive. This is why water is cohesive (can stick together): The positive ends stick to the negative ends.
To solve this we must be knowing each and every concept related to polar molecule. Therefore, polar and nonpolar molecules are covalent compound.
What is polar molecule?A polar molecule is a type of chemical compound where there is an uneven distribution of electrons among the covalently bound atoms.
The term "polarity" refers to how unlike two molecules' electrical poles are from one another. If they are quite dissimilar, the species is said to be an extremely polar molecule.
Because of the more symmetrical distribution of the electrons, non-polar molecules do not have a lot of charges on their opposing sides. The fees are all offset by one another. Polar and nonpolar molecules are covalent compound.
Therefore, polar and nonpolar molecules are covalent compound.
