rank the following diatomic species of boron in order of bond length and bond strength. ..... a. b2 ..... b. b2 ..... c. b2−

Answers

Answer 1

Ranking the diatomic species of boron in order of bond length and bond strength is as follows:

Boron is an interesting element because it exists as diatomic molecules in different forms. To rank the following diatomic species of boron in order of bond length and bond strength, we need to consider their molecular structure and electron configuration.

Firstly, let's look at b2, which is the most common form of boron molecule. The bond length of b2 is around 1.33 Å, and its bond strength is relatively weak due to the low number of electrons shared between the two atoms.

Secondly, b2+ is the ionized form of b2, which means it has lost one electron. This loss of electron results in a shorter bond length, around 1.2 Å, and a stronger bond compared to b2.

Lastly, b2− is the anion form of b2, which has gained one electron. The additional electron causes repulsion between the two atoms, resulting in a longer bond length of around 1.45 Å, and a weaker bond than b2.

Therefore, the order of bond length and bond strength for the diatomic species of boron is b2+ > b2 > b2−.

Answer 2

The diatomic species of boron in order of bond length and bond strength cab be ranked as: In terms of bond length, the order is:B2− > B2 > B2+, whereas, For bond strength, the order is: B2 > B2+ > B2−.

1. Bond length: As you go from B2 to B2+ to B2−, the number of electrons in the bond increases.

More electrons lead to greater electron-electron repulsion, resulting in a longer bond length.

2. Bond strength: B2 has the strongest bond because it has the optimal balance of electron sharing between the two boron atoms.

In B2+, one electron is removed, weakening the bond. In B2−, one electron is added, increasing electron-electron repulsion and also weakening the bond.

The yellow light given off by a sodium vapor lamp has a wavelength of 589nm. What is the frequency of this radiation? Please show all work.

Answers

Answer:

5.09 x 10⁶ s⁻¹ = 5.09 x 10⁶ Hz

Explanation:

The relation between frequency (ν) and wavelength (λ) is given by:

λ = c/ν

where c is the speed of light (2.998 m/s) and it is a constant.

So, we first convert the wavelength from nanometers (nm) to meters (m) (1 nm = 1 x 10⁻⁹):

λ= 589 nm x (10⁻⁹ nm/1 m) = 5.89 x 10⁻⁷ m

Then, we calculate the frequency from the equation:

λ = c/ν ⇒ ν = c/λ = (2.998 m/s)/(5.89 x 10⁻⁷ m) = 5.09 x 10⁶s⁻¹ = 5.09 x 10⁶ Hz

a.) atomic mass
b.) atomic number
c.) protons
d.)neutrons
e.)electrons
f.) ion
g.)neutral

Answers

changing the number of NEUTRONS makes an atom stable or unstable and creates different isotopes of the same element with a different ATOMIC MASS

The neutrons are the neutral sub-atomic particles present in the nucleus. The variation in the number of neutrons produces isotopes that have different atomic mass. Thus, options 1. d and 2. a are correct.

What is an isotope?

An isotope is said to be an atom of an element that have a different atomic mass but the same atomic number due to the variation in the neutrons in the nucleus. The neutrons have a neutral charge that makes the atom stable.

When a neutron is added or lost it makes the nucleus of the atom unstable leading to radioactive decay. The isotopes have the same constant number of protons in their nucleus.

The atomic number of the atom remains the same due to the stable proton number but varies the atomic mass due to the change in the number of neutrons.

Therefore, options d and a. neutrons and atomic mass are the correct blanks.

For the rxn CaCo3(s)+2Hcl(aq)_CaCl(aq)+Ca2(g)+H2O(l)68.1 g solid CaCo3 is mixed with 51.6Hcl what number of grams of Co2 will be produced

Answers

Answer:

29.9 g of CO₂ will be produced by the reaction.

Explanation:

This is the reaction:

CaCO₃(s)  + 2HCl (aq)  →  CaCl₂(aq)  + CO₂(g) +  H₂O(l)

First of all, we state the moles of each reactant:

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

The solid salt is the limiting reactant. Ratio is 2:1

2 moles of acid can react to 1 mol of salt

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

As we only have 0.680 moles of salt, we do not have enough.

Let's work at the product side. Ratio is 1:1

1 mo of salt can produce 1 mol of gas

0.680 moles will produce 0.680 moles of gas

We convert the moles to mass → 0.680 mol . 44g / 1mol = 29.9 g of CO₂

The number of grams of Co2 should be produced is 29.9 g.

Calculation of the number of grams:

Since

CaCO₃(s)  + 2HCl (aq)  →  CaCl₂(aq)  + CO₂(g) +  H₂O(l)

So,

68.1 g . 1mol/ 100.08g = 0.680 mol of carbonate

51.6 g . 1 mol/36.45g = 1.46 mol of acid.

Now the ratio should be 2:1 for the solid salt

And, there is 2 moles of acid can react to 1 mol of salt

So,

1.46 mol of acid may react with (1.46 . 1)/2 = 0.727 moles

Now the product side the ratio is 1:1

So, that means

1 mo of salt can produce 1 mol of gas

So, the no of grams should be

= 0.680 mol . 44g / 1mol

= 29.9 g of CO₂
