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:
Option B. 6 atoms of carbon
Explanation:
In <u><em>any chemical reaction</em></u>, atoms from reactant side and product side must be the same.
This is photosynthesis reaction:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
The 3% mass/volume H₂O₂ means 3 g of H₂O₂ in 100 ml of water.
Now, Molarity (M) = No. of moles of H₂O₂ / Volume of solution in liter
No. of moles of H₂O₂ = Mass / Molar mass = 3 g / 34 g/mol = 0.088 mol
So, molarity = 0.088 × 1000 ml / 100 ml = 0.88 M
In case of 2.25 % H₂O₂,
No of moles = 2.25 g / 34 g/mol = 0.066 mol
Molarity = 0.066 mol / 0.100 L = 0.66 M.
People who work with radioactive materials often wear a film badge to reveal how much radiation they have been exposed to. The film badge dosimeter or the film badge is a dosimeter worn by these people working with materials that are radioactive for the purpose of monitoring cumulative radiation dose due to ionizing radiation. The badge has two parts; the photographic film, and a holder.
Here is your answer
Since, carbon atoms are triple bonded.
So functional group present in the compound is ALKYNE
