Identify the Lewis acid in this balanced equation: Central N is bonded above, left, and below to C H 3 and has 2 electron dots t

notsponge [240]

A chemical substance that gains or accepts electrons from others is called lewis acids. The Lewis acid in the reaction is Trihydridoboron $(\rm BH_{3}).$

<h3>What are lewis acids and bases?</h3>

For the formation of the covalent bonds the molecule or the atoms that accept or gain an electron from the other species present in the reaction are called lewis acids. The species formed after accepting electrons are called a conjugate base.

The species that donates electrons to the other species are called lewis base and the species formed after the electron donation is called a conjugate acid.

Therefore, option B. $\rm BH_{3}$ is the lewis acid as it gains an electron.

30. The density of an unknown gas at 27°C and 2 atm pressure is equal with density of N2 gas at

Zanzabum

Answer:

Molar mass of the unknown gas is 64.6 g/mol

Explanation:

Let's think this excersise with the Ideal Gases Law.

We start from the N₂. At STP conditions we know that 1 mol of anything occupies 22.4L.

We apply: P . V = n . R . T

5 atm . V = 1 mol . 0.082 . 325K

V = (1 mol . 0.082 . 325K) / 5 atm = 5.33 L

It is reasonable to say that, if we have more pressure, we may have less volume.

As this is the volume for 1 mol of N₂, our mass is 28 g. Then, the density of the nitrogen and the unknown gas is 28 g/5.33L = 5.25 g/L

Our unknown gas has, this density at 27°C and 2 atm.

If we star from this, again: 1 mol of any gas occupy 22.4L at STP, we can calculate the volume for 1 mol at those conditions:

P₁ . V₁ / T₁ = P₂ . V₂ / T₂

1 atm . 22,4L / 273K = 2 atm . V₂ / 300K

Remember that the value for T° is Absolute (T°C + 273)

[ (1 atm . 22.4L / 273K) . 300K] / 2 atm = V₂ → 12.3L

This is the volume for 1 mol of the unknown gas at 2 atm and 27°C

We use density to determine the mass: 12.3 L . 5.25 g/L = 64.6 g

That's the molar mass: 64.6 g/mol

What does it mean to be in the path of totality science

defon

Answer:

The track of the Moon's shadow across Earth's surface is called the Path of Totality. This path is typically 16,000 kilometers (about 10,000 miles) long but only 160 kilometers (100 miles) or so wide. In order to see the Sun totally eclipsed by the Moon you must be in the path of totality.
