John Dalton’s atomic model described atoms as the smallest indivisible part of an element.

<h3>What are atomic models?</h3>

Atomic models are models which are used to represent the structure of the atom.

Different scientists put forward different models to represent the atom.

One of the scientists was John Dalton.

The features of Dalton's atomic model includes:

  • atoms are the smallest particle of elements
  • atoms are indivisible
  • atoms of the same element were the same and atoms if different elements differed in all aspects

Therefore, John Dalton’s atomic model described atoms as the smallest indivisible part of an element.

How many moles of KCl are contained in this solution?<br><br>0.486 L of a 2.0 M KCl solution
Vika [28.1K]

Answer:

0.972mol

Explanation:

Given parameters:

Volume of Solution of KCl = 0.486L

Molarity = 2.0M

Unknown:

Number of moles of KCl in solution = ?

Solution:

To find the number of moles of KCl in this solution, use the expression below;

  Number of moles  = molarity x volume

Insert the parameters and solve;

  Number of moles  = 0.486 x 2  = 0.972mol

A sample of a gas has a pressure of 248mm Hg when the volume is 1.05L. What is the pressure of the gas when the volume is 3.98L?
ozzi
P1V1 = P2V2
Convert 248mm Hg to atm
248/760 = 0.326 atm
(0.326 atm • 1.05L) / 3.98L = 0.0861 atm

Sodium borodeuteride is a commercially available reducing reagent that can convert aldehydes and ketones to the corresponding al
kupik [55]

Here we have to draw the mechanism of the reduction reaction between benzaldehyde and sodium borodeuteride to form the corresponding alcohol.

The reducing agent sodium borodeuteride can reduce the aldehydes to its corresponding alcohol. The reaction mechanism is shown in the attached image.

The reaction mechanism can be explained as-

The sodium borodeuteride is highly ionic in nature thus it remains as Na⁺ and BD₄⁻ The deuterium atom of BD₄⁻ attack the carbonyl carbon atom and substitute one of its deuterium as shown in the figure.

One molecule of sodium borodeuteride can reduce four molecules of benzaldehyde. The polar solvent like alcohol donates the proton as shown in the mechanism.

The converted alcohol contains the deuterium atom at the -C center. Thus benzaldehyde is converted to deuteroted benzyl alcohol.
