Lead is malleable, so it can be pounded into flat sheets without breaking. How does the bonding within lead help to explain this

property?
Metallic bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.
Covalent bonds involve valence electrons that are shared between two metal atoms, so the bonds are strong enough to resist the pounding.
Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded.
Covalent bonds involve valence electrons that are removed from one atom and given to another, so the pounding helps the electrons move.

The answer is Metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded. The metallic bond structure of lead forms a cubic crystal structure and the atoms can roll over one another without breaking the metallic bonds. This is especially because the p orbital electrons of lead can be delocalized and the electrons can be shared with other lead ions in the cubic structure of lead.

Answer: Option (c) is the correct answer.

Explanation:

In metallic bonding, the valence electrons are involved in bonding with many atoms.

As a result, valence electrons dissociate within their atomic core and form a sea of electrons which helps in binding the positively charged ions.

Thus, we can conclude that the bonding within lead help to explain this property as metallic bonds involve many valence electrons shared by many atoms, so the bonds can move around as the metal is pounded.

A sample of gaseous methyl ether has a mass of 8.12g and occupies a volume of 3.96L at STP. What is the molecular weight of meth
Naya [18.7K]
Molar volume is when 1 mol of any gas occupies 22.4 L at STP.
Methyl ether has a mass of 8.12 g,
Volume occupied - 3.96 L
If 22.4 L occupied by 1 mol of gas
Then 3.96 L occupied by 1/22.4 x 3.96 = 0.176 mol of gas
The mass of 0.176 mol = 8.12 g
Molar mass is mass of 1 mol
Therefore mass of 1 mol = 8.12/0.176 = 46.1
Molecular weight is 46.1 g/mol

Are the following solutions acidic, basic, ot neutral.
Slav-nsk [51]

Answer:

1) Basic

2) Basic

3) Acidic

Explanation:

pH of a solution is a measure of the H3O+ ions in the solution and hence reflects its acidity.

pH = -log[H3O+]

Solutions are classified as acidic, basic or neutral based on the pH range

-pH < 7, acidic

- pH = 7, neutral

- pH > 7, basic

1) [H3O+] = 2.5*10^-9M

pH = -log[H3O+]=-log[2.5*10^{-9}]=8.60

Since pH > 7, solution is basic

2)[OH-] = 1.6*10^-2M

pOH = -log[OH-]=-log[1.6*10^{-2}]=1.80

pH = 14 - pOH = 14 - 1.80 =12.2

Since pH > 7, solution is basic

3) [H3O+] = 7.9*10^-3M

pH = -log[H3O+]=-log[7.9*10^{-3}]=2.10

Since pH < 7, solution is acidic

Relate metallic bonds to the properties of metals.
loris [4]
Metallic bonds can conduct electricity. It depends on what type of metal you use because everything has a different chemical make up and different bond. Metallic bonds make it easy for some metals to be ductile meaning that they can be stretched into thin wires and they can also be malleable which means they can be pound into thin sheets. Also certain atoms will react with water to make rust.
