Answer:
The answer to your question is 8,32 L
Explanation:
Data
Pressure 1 = 104.5 kPa
Volume 1 = 3.4 L
Pressure 2 = 42.7 kPa
Volume 2 = ?
Formula
- To solve this problem use the Boyle's law.
P1V1 = P2V2
- Solve for V2
V2 = P1V1 / P2
- Substitution
V2 = (104.5)(3.4) / 42.7
-Simplification
V2 = 355.3 / 42.7
- Result
V2 = 8.32 L
Answer: hydrogen atom of a polarized molecule bonds with an electro negative atom.
Explanation:
Hydrogen bonds are special type of dipole dipole forces which are formed when hydrogen bonds with an electro negative element. Hydrogen bonds are strongest type of bonds .Example: Bond between Oxygen of one water molecule to the hydrogen of another water molecule as shown in the image below.
Covalent bonds are formed by sharing of electrons among non metals.
Ionic bond is formed by transfer of electrons between metals and non metals.
Dimethyl amine is Base. The basic character of it is due to the presence of lone pair of electron on nitrogen atom. The strength of amines is basically due to the presence of alkyl group attached to nitrogen atom. These alkyl groups donates electron to nitrogen atom hence increasing electron density on nitrogen and increasing its basic character.
When dimethylamine ( Kb = 5.9 × 10⁻⁴) is reacted with water it abstracts proton from water molecule convertion it into Hydroxide Ion (i.e ⁻OH). The reaction is as follow,
(CH₃)₂N + H₂O → (CH₃)₂N⁺H + ⁻OH
Answer:On these combined scales of pH and pH it can be shown that because for water when pH = pH = 7 that pH + pH = 14. This relationship is useful in the inter conversion of values. For example, the pH at a 0.01 M solution of sodium hydroxide is 2, the pH of the same solution must be 14-2 = 12.
