Silver nitrate, AgNO₃ is a compound which is a type of matter as it is made up of more than one type of element.
What is a compound?
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.

Aluminum has metallic bonds between its atoms. Which statement BEST describes the
valence electrons in aluminum?
are exchanged with nonmetal atoms
are exchanged with other metal atoms
are localized and stay between metal atoms
are delocalized and move between metal atoms
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
are delocalized and move between metal atoms
Explanation:
As the problem says, aluminum has metallic bonds. The main characteristic of metallic bonds is that the electrons are free to move between the metal ions (they are delocalized), thus being responsible for the good electrical conductivity of metals.

Describe the relationship between heat and the vibration of atoms (kinetic energy)
Answer:
As heat increases, kinetic energy will also increase.
Explanation:
As we heat a substance, the temperature will rise. The higher the temperature, the faster the molecules are moving.
why does the second row of the periodic table have 8 elements
short asnwer:
here are 8 elements in period 2 because all those elements have electrons in the second shell and no electrons in the third shell.
Explanation:
There are certain rules for arranging atoms in shells 1) Maximum number of electrons in a shell is given by the formula 2n^2. 2) The outermost ( valence) shell can accomodate only 8 electrons.

How does density affect the organization of earth?
A : The densest material is closest to the center
B : The density material is farthest from the center.
C : The densest material is near the center
D : Density differences allow Earth materials to mix freely. ( science by the way )
Answer:
Earth has layers because of density. Dense materials such as iron sank to the middle of the Earth, the center of its gravity. Less dense materials stayed at the top.
Explanation:
hope this help:)
The answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center
The earth is made up of different layers namely,
The crustThe upper mantleThe lower mantleThe outer core andThe inner core.Each layer goes from topmost to inner most and the density of each layer increases as we moves closer to the center of the earth.
So, the densest material is closest to the center.
So, the answer to the question, How does density affect the organization of earth is A : The densest material is closest to the center

Answer:
When you look only at the “before” and “after” of a change, you are considering it as static change. In this perspective, you look at change as a one-dimensional shift. A situation or object was one way, and now it is different because some outside force acted on it to make it change.

Which compounds can be made with the reaction benzene via electrophilic aromatic substitution using isopropyl chloride and AlCl3 as reagents (1 equivalent or excess).
Answer:
isopropyl benzene (cumene)
Explanation:
The reaction of isopropyl chloride and AlCl3 and benzene belongs to the class of organic reactions known as the Friedel Kraft alkylation.
The mechanism of the reaction involves the formation of a tetrahedral complex [AlCl4]^-.
The electrophile now is the isopropyl group which attacks the benzene to yield the product.

How many moles of silver would precipitate out when 3.6 x 10^23 atoms of zinc are combined in silver nitrate according to the following unbalanced equation? (Balance equation first!)
Zn + AgNO3 → Zn(NO3)2 +Ag
A: 1.67 moles
B: 1.2 moles
C: 3.34 moles
D: 0.6 moles
Can someone please help me with this I don’t get it at all.
Answer:
D: 0.6 moles
Explanation:
First we balance the equation:
Zn + AgNO₃ → Zn(NO₃)₂ + AgThere are two NO₃ species on the right side, so we put a two before AgNO₃:
Zn + 2AgNO₃ → Zn(NO₃)₂ + AgNow we put a two before Ag on the right, to balance the Ag atoms:
Zn + 2AgNO₃ → Zn(NO₃)₂ + 2AgThe equation is now balanced.
Now we convert 3.6x10²³ atoms of zinc to moles, using Avogadro's number:
3.6x10²³ atoms ÷ 6.023x10²³ atoms/mol = 0.6 molesThen we convert 0.6 moles of zinc into moles of silver, using the stoichiometric coefficients of the balanced equation:
0.6 mol Zn * [tex]\frac{1molAg}{1molZn}[/tex] = 0.6 mol AgThus the answer is option D.
