Explain how the structure and bonding in bromine account for it's relatively low melting point. [3]

2 answers:

Bromine molecules have covalent bonding. Bromine molecule is stabilized by weak intermolecular forces of attraction such as van der Waals forces of attraction. van der Waals forces are result of creation of instantaneous dipoles caused by the uneven distribution of the electron cloud. The weak intermolecular forces of attraction account for the lower melting point of bromine.

Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure the intermolecular bonds of bromine are weak bcz they are weak vandervaal forces thats why Bromines melting point is low..In short when intermolecular bomds are weak the M.P is lower

Based only on the distance between the valence electron and the nucleus, which atom has a stronger attraction between its nucleu

nirvana33 [79]

Answer:

The atom having less atomic size.

Explanation:

Because the atom having less atomic size means having less atomic number are more close to nucleus so it having more attraction with respect to having large atomic size as it is far from the nucleus.

How does technology limit the future of space exploration? A. Scientists are able to work both with current and future technolog

GREYUIT [131]

The answer is most likely that the answer is B. Because Space is a dangerous place in which you need certain things to explore it. If you want to go to to Jupiter, for example you need lots of Oxygen, fuel, a good rocket, willing people and many more things, but there is a way technology can skip all that. the technology we have now is not capable of doing that though.

A compound is found to contain 63.65 % nitrogen and 36.35 % oxygen by mass. what is the empirical formula for this compound?

kodGreya [7K]

Let the total mass of the compound is 100 g.

Mass of N = 63.65 % = 63.65 g

Mass of O = 36.35 % = 36.35 g

Molar mass of N = 14.01 g/mol

Molar mass of O = 16.00 g/mol

Number of moles (mol) = mass (g) / molar mass(g/mol)

Number of Moles of N = 63.65 g / 14.01 g/mol = 4.54 mol

Number of Moles of O = 36.35 g / 16.00 g/mol = 2.27 mol

Divide the Number of moles of each element with the lowest number of moles, here lowest number of moles is 2.27 .

Dividing number of the moles of each element by lowest number of moles to get the mole ratio between elements.

N = 4.54 mol / 2.27 mol = 2

O = 2.27 mol / 2.27 mol = 1

So, Empirical formula = N₂O₁ = N₂O

How was it first discovered that hot air could rise?

Sunny_sXe [5.5K]

The history of balloon flight dates to 1783, when two French brothers, Joseph and Etienne Montgolfier, discovered that filling a bag with hot air would cause it to rise. They demonstrated their principle at Annonay, France, on June 4, 1783, with an unmanned balloon made of linen and pape

A3B8 + C2 ---> AC2 +

AURORKA [14]

Answer:

A₃B₈ + 5C₂ –> 3AC₂ + 4B₂C

Explanation:

A₃B₈ + C₂ –> AC₂ + B₂C

The equation can be balance as illustrated below:

A₃B₈ + C₂ –> AC₂ + B₂C

There are 3 atoms of A on the left side and 1 atom on the right side. It can be balance by writing 3 before AC₂ as shown below:

A₃B₈ + C₂ –> 3AC₂ + B₂C

There are 8 atoms of B on the left side and 2 atoms on the right side. It can be balance by writing 4 before B₂C as shown below:

A₃B₈ + C₂ –> 3AC₂ + 4B₂C

There are 2 atoms of C on the left side and a total of 10 atoms on the right side. It can be balance by writing 5 before C₂ as shown below:

A₃B₈ + 5C₂ –> 3AC₂ + 4B₂C

Now, the equation is balanced.
