In the lewis formula for sulfur dioxide, so2, the number of lone pairs of electrons around the sulfur atom is?
Nastasia [14]

The molecule of sulfur dioxide has two pi and two sigma bonds and one lone pair of electrons.

<h3>What is lone pair?</h3>
  • A lone pair, also known as an unshared pair or a non-bonding pair, is an unshared pair of valence electrons that are not shared with another atom in a covalent connection in chemistry.
  • Atom's outermost electron shell contains lone pairs. The Lewis structure can be used to locate them.
  • Due to the high electric charge of a lone pair, which results in strong electron repulsion, the bond angle between the bonding pair of electrons reduces.
  • They participate in the creation of a dative relationship as well.

What happens to Kinetic?<br> energy during gas particles collision
Vitek1552 [10]

Answer:

Gas particles are in a constant state of the  random motion and move in straight lines until they collide with another body. The collisions exhibited by gas particles are completely elastic; when the two molecules collide, total kinetic energy is conserved.

Hope it helps!

Hydrogen gas is produced when zinc reacts with hydrochloric acid. If the actual yield of this reaction is 85%?
solong [7]

Answer:

d. 380g

Explanation:

The reaction of production of hydrogen from zinc and HCl is:

Zn + 2HCl → ZnCl₂ + H₂(g)

At STP (1atm of pressure and 273.15K), 112L are:

n = PV /RT

n = 1atm×112L / 0.082atmL/molK×273.15K

<em>n = 5.00 moles </em>

That means you need to produce 5.00 moles of hydrogen. Based on the reaction, 1 mole of Zn produce 1 mole of H₂(g), as yield of reaction is 85%:

5.00 moles H₂(g) ≡ 5.00 moles of Zn / 85% = <em>5.88 moles of Zn you need</em>

As molar mass of Zn is 65.38 g/mol:

5.88 moles Zn × (65.38g /mol) = 384 g of Zn ≡ <em>d. 380g</em>

<em></em>

I hope it helps!

What is the best name for the following compound? CCl4
Nitella [24]

Answer:

The answer is b. Carbon Tetrachloride

Explanation:

Let's discard the other options:

a. It couldn't be carbon chloride because there are four (4) chloride ions in the molecular formula. The molecular formula for the carbon chloride must be CCI. So, this answer is wrong

c. It could be monocarbon tetrachloride because there are 4 chloride ions and 1 carbon ion, but it's not necessary to use the prefix "mono" because there is just one carbon ion in the formula. In that way, when we mention carbon in the name, there is implicit that there is just one carbon atom in the formula. So, this answer could be ok, but isn't the best.

d. It couldn't be calcium chloride because there isn't any calcium ion or atom in the formula. The molecular formula for the calcium chloride must be CaCI. So, this answer is wrong
