Why are the molecules of hydrocarbons nonpolar?
laiz [17]
<span>This is not the case in the hydrocarbon tail. The electronegativity of hydrogen and carbon are very similar, so the electron cloud is distributed evenly over the two atoms. Carbon-hydrogen bonds are said to be non-polar because they do not have positive and negative poles within themselves. Hope this helps. </span>

How many molecules in 9.18 moles of C11H12O22
Setler [38]

Answer:

55.3 × 10²³ molecules

Explanation:

Given data:

Number of moles of C₁₁H₁₂O₂₂ = 9.18 mol

Number of molecules = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

For given data:

9.18 mol × 6.022 × 10²³ molecules /1 mol

55.3 × 10²³ molecules

What volume of chlorine gas measured at StP will be liberated by a current of 2.5 A flowing for a period of 1.8 hours through an
Oliga [24]

The volume of chlorine gas measured at STP will be liberated by a current of 2.5  A flowing for a period of 1.8 hours through an aqueous solution of AgCl is 1.88 litre.

<h3>What is Faraday's law ?</h3>

According to Faraday's Law , During Electrolysis , The amount of substance liberated at the cathode or anode is directly proportional to the electricity that is passed through the cell.

The reaction taking place at anode is:

2Cl → Cl₂ +2e −

The total charge is calculated as

Q=I×t= 2.5×1.8×60×60 coulomb

Q = 16200 coulomb

The amount of chlorine liberated by passing 16200 coulomb of electric charge

= 16200/(2*96500)

= 0.084 mole

Volume of Cl₂ at STP is

​1 mole at STP has 22.4 L of Gas

0.084 mole of Cl₂ at STP will be equal to 22.4 *0.084 = 1.88 litre of Cl₂
