<span>Answer:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.</span>
Answer:
butan-2-ol
Explanation:
The reaction is of an alkene with water in acidic medium. This will give addition product where water will add on the alkene according to Markovnikov's rule.
However, as alkene is symmetrical,w we will get single addition product.
The steps will be
a) There will be protonation of alkene with the acid (the catatlyst), resulting in formation of carbocation.
b) the carbocation formed will be attacked by water molecule, following by deprotonation to give alcohol.
The reaction is shown in the figure.
Answer:
alkyl halide + 2 (ammonia) → alkyl amine + ammonium halide
Explanation:
In this type of preparation of alkyl amine this process works through substitution nucleophilic second order reaction and the nucleophile in this case is the ammonia and the leaving group will be the chloride ion
When ammonia attacks opposite to the way in which leaving group leaves, the chloride ion will be leaved and the nitrogen attains positive charge
So one of the hydrogen attached to the nitrogen will be removed and as there is another mole of ammonia and as ammonia is a base, it takes that hydrogen and it will form ammonium ion and to this ion chloride ion will get attracted as both have opposite charges and at last alkyl amine and ammonium halide will be formed
Answer:
<em>The pH of the solution is 7.8</em>
Explanation:
The concentration of the solution is 0.001M and the dye could be in its protonated and deprotonated forms. If the concentration of the protonated form [HA] is 0.0002 M the concentration of the deprotonated form will be the subtraction between the concentration of the bye and the concentration of the protonated form:
[A-] = 0.001M - 0.0002M = 0.0008M
Also, the Henderson-Hasselbalch equation is
this equation shows the dependency between the pH of the solution, the pKa and the concentration of the protonated and deprotonated forms. Thus, replacing in the equation
Actually, I think you meant :A path that electric current follows is a circuit..
Hope this answer helps!
